mspgcc compiler will assume a size of one if this declaration is used on global scope and refuses tho compiler if used locally. With the 'extern' keyword on global scope., mspgcc accepts it but then it needs to be defined elsewhere or the linker will complain.

Doing it in plain C is also possible, but much slower as it requires a division or a loop of subtractions. Still faster than sprintf:

The answer is inconclusive. Both IPS and PLS monitor types certainly have their advantages. Although PLS is slightly better in terms of backlighting and faster response times, the margins for improvement are fairly tight. It really just depends on what your preferences are as well as the applications that the monitors are being used for.

IPS vsLED

I’m trying to transmit data from MSP430FG4618 to a PC via RS232. The baud rate setting is 115200bps with 8 data bits and 1 stop bit (no parity bit and no flow control). In the other words, if I’m correct, each character (byte) I send from MSP430 to PC is 9 bits. Therefore, at 115200bps, I can send a maximum of 115200/9=12800 characters/sec. As shown in my following code, I’m sending 128000 characters and it takes 11 seconds to complete. It takes 110 seconds to send 1280000 characters. In the other words, it’s about 10% slower. I think there might be one of the following possibilities:

Second parameter to the function is a pointer to the destination (as used in sprintf as the first). So you need to pass a pointer.

I have a numerical data that is to be sent to PC via RS232 at 115200 bps.  In order to do that, I need to convert the numerical data into ASCII text before transmission.  However, the conversion is very slow in MSP430 with sprintf command.  As shown in the following, if I remove the first line, it sends as fast as I expected.  Once the first line is there, it slows the transmission at least 10x slower.   Any better way of transmitting numerical data via RS232?  (by the way, the numerical data is continuous on the fly - From an ADC.  Therefore, I can't store it into buffer before transmitting.)

PLS stands for plane to line switching. Also referred to as Super PLS Panel, this technology boasts superior technological advancements such as a multitude of brightness setting options, crystal-clear image quality, and adjustable viewing angles without breaking the bank.

You already have a trusted clock (from which you get your baudrate), so please us it in conjunction with a timer for making a delay.

I thought about doing that, but don't know how to send the data to PC without converting the numerical value to ASCII characters.  Would you please give me a hint on this?  See my previous code.

If "your_data_16" is 16-bit wide, you need to send it in 2 installments. Do a TXBUF=(char)(your_data_16 & 0xFF); first, and a TXBUF=(char)(your_data_16 >> 8); the next time in two consecutive opportunities to do so.

PLS monitors offer superior viewing angles when compared to IPS displays. Unlike IPS displays, PLS monitors don’t have any noticeable colour distortions and they have significantly lower production costs.

If using [] to define an array, the name of the array may be used as pointer too, but it is not a pointer variable (no memory location that holds the address of the data) but rather a label whose value is known to the compiler and directly used as immediate value.

Actually, the easiest and fastest way to send data over UART is to send them as is without any conversion. Assuming the UART format is 115200,8N1, you can send 8-bit worth of data in 10/115200 seconds. That is 80% efficient. If you convert that data into hex digits, you can only send 4-bit worth of data in the same amount of time and is only 40% efficient. If you convert to decimal digits, aside from the time you spent for conversion, you can only send ~3.3 bits worth of information and is only ~33% efficient. The PC has Meg bytes of memory and GHz CPU, why not let the PC to do the conversion?

void SendData(unsigned char c){        while(!(IFG2 & UCA0TXIFG));   //Wait until transmit buffer is empty        UCA0TXBUF = c;                 //Send character}

Alternatively, you can define an array, but then it must be initialized (not its content, but its destination). Thechar mystring[];you used does not allocate memory for the array. You need to define how large this array has to be. It is only allowed to use this kind of 'undefine dsize array' in an extern declaration, trusting that the 'real' array is properly defined in a different code file.

From an aesthetic and logistical standpoint, PLS panel types are also thinner than IPS due to the fact that the glass sheets that hold the liquid crystals in place are positioned much lower in the screen configuration.

Note, that directly typed this code for this thread. I never tried to compile it myself. I'm surprised that there weren't more typos. ;)

There are two different ways to convert integers. The fastest and easiest would be to send hexadecimal numbers. It allows masking of 4 bit groups and avoids slow divisions.

Colour contrast and brightness is a central concern when purchasing a new commercial or industrial display. Whether you’re a gamer or graphic designer, your best option in this regard is to stick to IPS displays. They offer far more consistent image quality, colour contrast, and brightness that’s perfect for applications that rely heavily on high-quality image production.

It's not much optimized, but should produce the desired result without leading zeroes (if you want them, remove the IF cases, or add an else case if you want leading spaces instead). Best of all, it just uses subtractions but no divisions which are slooooooow on the MSP.

If your data is still too fast for hte PC, then the PC is too slow to receive the data. Well, 115200 shouldn't be a problem normally. I sometimes have 2 or 3 terminal windows open with 115200Bd data coming in. Plus some network connections. And I never had  a problem despite the fact that my PC is an old Athlon Xp. In fact I can compile in th e background and don't notice any character loss. But then, my connections are real RS232 connections, not routed through USB. Maybe there's a bottleneck.

FOR loops are not suitable for delays. Depending on th eproject settings and the compiler used, this kidn of loops can be optimized down to an empty function. A good compiler will notice that nobody except the local function can possibly know the location of the loop variables, their value is never used except for limiting the loop and therefore the whole loop has no effect and can be eliminated.And if your MCLK speed changes for some reason (maybe in a different project on an MSP with a faster crystal), the delay changes its duration even if the compiler does not optimize this code. And all you will see is that the previously working code is suddenly broken.

I used your updated convert() and the conversion seems to work for the first 99 numbers, after that, it skips by 10 at 100.  There are also some numbers not displaying correctly (middle of the 3 digit numbers).  Same thing happens at numbers more than 999.

When it comes to choosing the right panel type of your LCD monitor, the options are seemingly endless. We’ve discussed the differences between AMOLED and LCD displays as well as the different types of touchscreen monitors that are commonly used for various devices and their benefits. Now it’s time to learn about the different features and specifications of PLS and IPS panels so you can decide which one is the most suitable choice for your specific personal or professional applications.

PLS panels for LCD monitors have been on the market for over a decade and have proven to be a worthy adversary for their IPS predecessors. Although the technology is the same for the most part, IPS does offer some minor improvements. The main difference is that IPS panels offer more optimized liquid molecular alignment, which makes for a slightly better viewing experience. Hence, PLS screens offer 15% more brightness than IPS panel types.

If you define char * mystring, then mystring is a pointer to char(s). *mystring is the value of the location mystring points to, a char value. To have it work, mystring needs to poitn to a reserved memory location, such as one located with malloc(). So if you need 5 bytes for the buffer, you'll have to use

PLS panel types have been proven to have superior colour distribution and accuracy compared to IPS panel types. PLS displays have a far more expansive colour gamut that’s ideal for users who require the most natural-looking images and colour options.

Originally, the code was just an example stub with the 1000 while, then I thought I could as well extend it to cover the other digits as well. But I forgot to re-initialize the digit count when hopping to the next digit. This gives the following digits a 'head start' ;) (and of course once it reaches a value >9 it will start showing non-number values).

hey, as a side effect, it makes calculations of throughput against baudrate much easier - just drop the last zero of the baudrate :)

Unfortunately, PLS and IPS monitors both have a fairly slow response time (the amount of time it takes for liquid crystals to shift from one colour or shade to another). For this reason, neither one is the ideal choice for gaming purposes, but they’re both suitable for graphic design projects that focus more on colour distribution and accuracy than response time.

It is very fast now.  Perhaps too fast?  It works only if I put some kind of delay before transmitting to PC.  The PC indeed receives the spaghetti characters as expected.

The delay before sending to the PC shouldn't be necessary - normally. 1ms (if it is 1ms) is 10 bytes! so you're dropping your effective throughput down to 1/6 of the 115200 Bd. And even much less, since you don't send to the PC and to the display simultaneously. But this would require asynchroneous handling with a send/receive buffer and ISRs.

As mentioned, IPS LCD monitors contain hundreds of liquid crystals that are situated between two glass sheets in a parallel formation. As electric currents run through the liquid crystals when the screen is turned on, they become animated and move in different directions and backlighting passes through them. This is what produces the crystal-clear and instantaneous images you see on the screen. The excellent viewing angles are the result of the horizontal movements of the liquid crystals inside the panel.

If "your_data_8" is 8-bit wide (that is, if it is of type "char", "unsigned char", "signed char", "u8", "s8", or whatever you call it) you can simply do a TXBUF=your_data_8 whenever TX is ready for data.

When it comes to comparing and contrasting the differences between IPS and PLS LCD monitor panel types, the competition is pretty stiff. Both monitors are fairly similar with the exception that PLS is meant to be an improvement on the previous technology. Here are the key factors that should be considered when deciding which one is the best monitor panel for LCD industrial displays.

If you want normal decimal, you can use the BCD assembly commands like DADC to convert the number (in the range of 0..9999) to a binary coded decimal (one decimal digit per 4 bits) and then do a simplified hexadecimal conversion (the 'A..F' value won't happen) of the 4*4 bits.It is MUCH faster than sprintf, but it requires usage of assembly language.

void convert (unsigned int value, unsigned char * dest){  unsigned char digit = 0;  unsigned char flag = 0;  while (value => 1000){    digit++;    value -=1000;  }  if(digit || flag){    *dest = digit+48;    dest++;    flag=1;  } while (value => 100){     digit++;     value -=100;   }   if(digit || flag){     *dest = digit+48;     dest++;     flag=1;   } while (value => 10){     digit++;     value -=10;   }   if(digit || flag){    *dest = digit+48;    dest++;    flag=1;  }  *dest= value+48;  *dest++;   *dest=0;  return}

Can anyone answer my question? Thanks.//Sending 128000 characters to PC at baud rate of 115200bps.  It should take about 10 seconds to send//each character has 9 bits (8 data bits + 1 stop bit)

Backlight bleed occurs when the lights from the back of the screen leak through the edges, which results in uneven lighting or glow. This is a fairly common shortcoming of IPS screens when the brightness is adjusted to a particularly high level and can make for a poor viewing experience. PLS panel types don’t have this problem and offer even lighting regardless of the brightness settings.

IPS stands for in-plane switching. It’s one of the most commonly used monitors for LCD displays and it consists of two glass panels that hold a layer of liquid crystals in between them. The liquid crystals become animated and perform predetermined actions such as moving in a specific direction or displaying certain colours when they’re charged with an electric current. These actions result in the high-quality images that appear on your television, laptop, or smartphone screen.

Both LCD monitor panel types have their advantages and disadvantages for various types of applications. Finding out how they work will help you determine which one is the best choice for your needs.
