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
Hi, Thanks for sharing the experience and timely support.I am new to STM32 controller and OTA programming. Kindly share the suggestion for the below queries.Environment - STM32F205ZGT7, IAR workbench, ST-Link V21) Which executable file(.hex,.out,.bin...
I am trying to use the ADC_Read block from the simulink support package. I am able to use the ADC1 from a STM32F4 MCU but when I try to use the ADC from STM32F0 MCU it doesn't work. All the configurations should be fine since many other blocks work (...
