Resolved! How to read byte from SPI?
There is some way to read directly the byte that are send via SPI and not the int8 that is generate by the function?int8_t buffer[BUFFER_SIZE] HAL_SPI_RECEIVE_DMA(...,(uint8_t*)buffer,...,...)

Resolved! Can STM32L4S9AII6 MCU SPI1 be configured as slave and accept 8-60MHz clock from master?
Can the STM32L4S9AII6 MCU SPI1 be configured as slave and accept a 8-60MHz clock from master? Section 52.2 (page 1852) of the STM32L4S9AII6 reference manual says "Slave mode frequency up to fPCLK/2.", but with the system clock configured in MxCube as...
Resolved! Memory issue
Dear community membersWe are using Quad SPI in stm32l476 while having a memory to read data but we are facing an issue. Garbage values when entering memory mapped mode.why is that?Thank you.
Resolved! While sending data on to USART1, I always get FEIF DMA errors. Why?
So I am setting up the DMA for USART1 tx on a STM32F4 on each transfer, and busy wait for it to be done (no interrupt) by polling TC. DMA2_Stream7->NDTR = len; DMA2_Stream7->PAR = (uint32_t)&(USART1->DR); DMA2_Stream7->M0AR = (uint32_t)str...
Resolved! FOTA/FUOTA Delta firmware with STM32
I'm new to the STM32 and I wanna know how can I make a Delta firmware ? If anyone have an idea or have already worked on it, please share it with me.Otherwise, is it possible to make a program that take the initial firmware and only update the addres...

SWV working on Nucleo-F446ZE but not on Nucleo-F767ZI or STM32F769-Disco
I've created three (nearly) identical test projects, one for a Nucleo-446Ze, one for Nucleo-767Ze and one for a STM32F769-Disco. They are all nearly identical: 1) Trace Asynchronous SW 2) FreeRTOS 3) A single task created for each user LED to blink t...
Resolved! DMA transfer is completed before transmitting all the data to SRAM (or data is corrupted)
I am currently working on a touch screen for one of our products. I built an LCD intel 8080 driver with the FMC and it's not working with DMA.The image is only partially flushed to the screen. It seems that there is some kind of limits to the transfe...
Proper way to send 16 bit SPI data
I need to send 8 bit and 16 bit data with my 32f769. I found a register modification routine to change the bits from 8 to 16 and back. I checked the SFRs and it works (changing the bits that is),When I transmit 8 bit data, all is fine. I can send ...
