In HAL_UART_RECEIVE_Dma ( 11) Suppose I am expecting multiple strings of size 5 byte 6 byte 11 byte What size should I mention then , In this receive dma function ?

Hi when i try to load the keil coding, it says that "No ST-LINK detected" and i cannot enter debug mode. I'm pretty sure it's connected using LAN.

@mutexembedded2206 2 жыл бұрын

Not sure, you probably need to check Debugger Settings, I normally use USB ST-Link.

how many bytes u want to send send that size of bytes it will receive ..otherwise u won't get ..and add carriage return and line feed if u want to send some bytes in provided bytes..i also faced same prob now it is working

@nicolasmosqueraseligmann4904 6 жыл бұрын

Hi, you sent "Hello World ", that it's exactly 11 characters, i know if you send less DMA interrupt won´t be called, but what happen if you send more, or even if you dont know how many bytes you would receive per stream???

@mutexembedded2206 6 жыл бұрын

Hi, I usually write a basic handshaking packet, something like this: 1. DMA expects 4 bytes = '*', 0x00, 0x08, '#', where 0x0008 is the size of data will be sent. 2. When this start packet is received, UART DMA is started again to wait for 8 bytes. Then, the cycle is repeated. [You can do your own handshaking protocol] Hope this helps

@nicolasmosqueraseligmann4904 6 жыл бұрын

thanks, that's a good idea, by chance do you know any way to re-target TX UART to printf through DMA and using a circular buffer

TheSolderingGuy007 Hi, Are you still having this issue? Did you use HAL_Delay in the Uart rx callback?

@TheSolderingGuy007 6 жыл бұрын

yes. still having the issue. no I dont have HAL_Delay in my callback. I tried making the callback as small as possible. I just have one statement in it (z++;) to increment a global variable.

@epiendless1128 4 жыл бұрын

The HAL designers seem to have a fetish for writing receive functions that require an exact number of bytes, for interfaces that are inherently for variable-length data. They do the same thing for SPI slave.

Hi thank you for this tutorial, can you please explain how to use HAL_UART_Transmit_IT function , i didn't understand its behaviour and it doesn't seem to be working like the HAL_UART_Transmit function

@armincal9834 3 жыл бұрын

It uses interrupt instead of polling method so you have to allow global Interrupts for your desired UART/USART pin for it to work

@robertmcvickers5975 4 жыл бұрын

This was 7 months ago so my memory on the exact terminology is a bit hazy, but I can give you a general description of the solution I found. You can access the UART by going to the /dev folder. Use ls, there are a lot of entities in here so you have to go slow and find the correct one. I think it is called ST-LINK. You can open that using netcat tool via the netcat command. Failing that I think I also just used cat on the port / file. I believe they are ports but are treated as files, they being tty1, stderr, stdin.
