uint8_t my_buffer[ 1B_LEN_PREFIX + 24B_LEN_DATA + nB_LEN_SUFFIX ] = {0};
(void) HAL_SPI_TRANSMIT_DMA(&hspi2, &my_buffer[0], sizeof(my_buffer)); I'm using the SPI TX line only to drive an addressable LED, making a custom waveform from SPI bits to...
Lines 19 and 26 are repeated. Mode is set to normal (0x0000) twice. The structure is already initialized to `={0};` it doesn't need to be overwritten once, let alone twice.Initialized for STM32H563.usart.c /* GPDMA1_REQUEST_USART1_TX Init */

I'm trying to set up a DMA transfer from UART1 periheral to memory. Using LL drivers. Using STM32Cube for "convenient" setup. It puts the all the USART peripheral init in usart.c. Where for GPDMA it does something like: /* GPDMA1_REQUEST_USART1_R...
It's a niche application. STM32H5 QFNI need SPI2_MOSI to make a specifically shaped wave. SPI is works well for this. I do not need the SPI_CLK pin/function. I set Cube MX to SPI2 Transmit Only Master, and of course it applies the CLK pin because alm...
Here is my attempt at background as I understand it... iROT is a ROM program in the STM32H563. It contains a P256 EC algorithm, and checks some section of FLASH that you define as a program for a signature, then jumps to it. The definition of the pro...
It's not an issue of leading. I'm ok with that padding, and it's fine. The issue is the number of bytes held low, doesn't matter until it does. It's not the value I'm ending on. It's not an amount of time I'm holding for the LED data line low. It's a...
UPDATE: Confirmed does not work.At least the STM32H63 will not allow SPI to transmit at least in TX ONLY MODE unless a TX pin and a CLK pin are set to alternate function mode.
The GP1DMA UART for U5/H5 works using linked lists for chaining transfers. Many (most) of the time you would want one transfer repeated over and over. Like UART downloading to a single circular buffer over and over.The default instance for MX setup ...
Thanks for the time it took to answer but that is not helpful. If I could easily test this, I would. It will be a couple weeks until I can get a development unit in hand, and I'd like to try and make plans for the layout. Perhaps someone else can ans...
First I'm not answering depending on the number of parts you buy. I just try to help on my spare time.Secondly, STiROT is supposed to be used with 2 slots, and was certified in this configuration.I appreciate your help. It was more the ridiculous not...
