I was having problems, without DMA worked but using DMA no, on the cubeide, the problem was the missing "HAL_SPI_MspInit(&hspi1);", it wasn't done on the build! It may help someone so here it is! Cheers!

Hi I had the same fucking problem, I spent 4 days trying to understand what was wrong... Is that a bug in STM32CUBEIDE? We must report this issue. Thank you!

Oh man, you absolute lifesaver, it wasn't working for me either until I added that line of code. Must be a bug in CUBEIDE. Thank you!

Hello julio can you please tell us where should we put "HAL_SPI_MspInit(&hspi1);"

We have IRQ handlers from DMA interrrupts, however we implement the callback from SPI interrupt? A bit confusing...

How is the SPI CS handled?

@bennguyen1313 4 жыл бұрын

If a SPI port has multiple SS pins that can be used (PE4, PE11, etc), the main.c's MX_SPI4_Init() enables /disables the SS: hspi4.Init.NSS = SPI_NSS_HARD_OUTPUT; hspi4.Init.NSS = SPI_NSS_SOFT; However it's in the stm32h7xx_hal_msp.c file (HAL_SPI_MspInit()) that defines *WHICH* SSN pin to use!! But is it possible to enable SS (SPI_NSS_HARD_OUTPUT), but *IN-ADDITION* manually take control of the pin like HAL_GPIO_WritePin (SPI4_NSS_GPIO_Port, SPI4_NSS_Pin, 0);

I try to use HAL_SPI function with the IC74HC165 but i can not receive the data. if you have experience about the CubeMX or example the source code, could you please share?

@sarpdaltaban 4 жыл бұрын

Could you give an example with separate RX and TX callbacks? Like: HAL_SPI_Receive_DMA(&hspi1, &receivedData, 1);

The NSS Pin need not set?

@LouisChouraki 5 жыл бұрын

Personnally, if I reset it before HAL_Transmit_DMA and set it after, I have a wrong value. If I don't do this I have shifted-bytes value (the shift change when I reset), that's usually a problem when you don't set NSS pin. So... I think you have to but I don't know where to set and reset the pin. If you find it out, please let me know

Curious as to why you don't open the project after you generate code....

In case you had installed few different Eclipse based toolchains there were issues in older versions of STM32cubeMX to properly opening the proper IDE.

I am not receiving the data in STM32 cube id by using STM32H750B-DK board

@hossamalzomor3311 3 жыл бұрын

Thanks for the lab, but I think SPI DMA example will not be complete without HW controlled NSS. in order for this lab to be useful , kindly consider repeating it with HW controlled NSS

tried on stm32cube ide on 19/9/20 and it worked on a nucleo f091rc.. be careful to connect on pin declared on .ioc pinout configuration listed on spi1 gpio settings and change SPI_DATASIZE_4BIT default to SPI_DATASIZE_8BIT

it would be better if they showed how to do it with CMSIS

STM, i'm not sure how much u work with microcontroller (u remark the sarcasm) but in my opinion you have 2 major bugs in your structure. Why did you designed the interrupt of UART and SPI to de deinit after it received the data?? Because that's what you do, you set the pointer to NULL. Why?? Also the second problem, why it is nessesary to receive a specific amount of bytes? If you communicate with uC via PC you don't know how many bytes you will receive, but that's what you have to know to make this interrupt work. Otherwise it won't call the callback untill you send the correct amount of bytes. After every com you have to reinit UART/SPI and set the correct amount of bytes beeing received. Thats not efficient neither usefull. It would be much better if you just reset the array number after the buffer end has reached and start from 0. Also an option for a message end command would be nice too. I can do all this on my own, but for the ppl out there without expirience it would be very helpfull.
