I faced strange behavior on STM32L431CC. I was trying to sequentially add data to archive and at some point the CPU failed to program 8 bytes at address 0x8032018 (8 byte aligned) and at address 0x8034100. I read data from the memory and it is clear ...
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,...,...)
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...
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.
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...
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...
It keep saying that I can't have links in my post because I am new. There are no links in my post.And because I am new, of course I have questions :(Garrett
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...
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...
