I am learning bare-metal programming on STM32F411RE (Nucleo board). I am trying to implement a SPI driver.Reference manualEven though I have set the Data Frame Format to 8-bit, My SCK consists of 16 clock cycles. Sending 8 bit data on this has weird ...
MCU is STM32H743ZI. When QUADSPI working in AutoPolling mode,Setting the ABORT bit in the QUADSPI_CR, Why SR.BUSY bit stall high? BUSY don't goes low forever!But according to referrence manual,"In automatic-polling mode, BUSY goes low only after the ...
What kind of reason would the DR register read the same on subsequent calls in release build?If I don't add __NOP()'s in there, the registers read the same and the FIFO doesn't get emptied.Micro is STM32F769NIstatic uint32_t drvInit(void) { uint32...

I’m designing a motor control PCB with two STM32G432RBs (situated close to each other on the PCB) driving a boatload of H-Bridges, encoders, servos, and other I/O. I’m planning a dedicated (synchronous) USART connection between the two STM32G4s to ke...
Hi,On the Disco board with STM23F4x there is a STM32F1003.What is it there for, and how do I access it?Thanks,Johannes
I use circular DMA with a buffer of size n (on a G431) to create bursts that are not necessarily equal to a multiple of n in size. This works fine, I start and stop a timer and end up somewhere in the DMA buffer array (say, at buffer[m] where 0<=m<n)...
Hi there,I use an STM32L433 and have to evaluate a quadrature encoder in a battery device.For this I want to use the LPTIM1 in encoder mode.My problem is that the 16 bit of the timer is not enough to save the desired position.As soon as there is an o...
As I understand it TI mode consists of high polarity clock, 1st edge phase and nss after every frame. I think the problem I have is the clock is running even with NSS high. This causes the bits to be shifted out of the ADS7953. It will be great if an...
I'm trying to code IR remote which uses NEC protocol using STM32f030 .I'm able to do the code under while(1) as as a GPIO input But i'm not able to implement it as an interrupt . Kindly help me regarding the same
