Can the STM32G0 SPI peripheral be configured for 3-wire SPI instead of 4-wire SPI for bidirectional data flow? Thanks!

The reset source identification register (RCC->RSR) of the STM32H7 is zero after a watchdog reset.

After causing a watchdog reset RCC->RSR is showing as 0. I didn't think that was a valid value unless a jump was performed. I check RSR first thing so nothing should be clearing the bits by setting RMVF bit. Other types of reset seem to work. I haven...

losing some isr

Hello dear experts,I am using the TIMER2 on stm32F446Re with TI1_ED as reset mode input and TIM2_CH4 as timer value capture input. I inserted code to toggle a gpio in the HAL_TIM_IC_callback. On the scope I am capturating the TIM2_IC4 signal and the ...

ADC DMA with TIM21 TRGO conversion source on STM32L010

I've got an application where I'm performing an ADC DMA transfer where the ADC conversions are triggered by the TIM2 TRGO. Everything was running smoothly until a PCB respin forced me to switch over to TIM21 to trigger the conversion. I didn't see a ...

Can we capture image from camera in RGB888 format using STM32F4DIS-CAM on STM32F746NG target board?

I am using STM32F746NG(DISCO_F746NG) with camera(STM32F4DIS-CAM) to capture images by using https://os.mbed.com/teams/ST/code/BSP_DISCO_F746NG//file/85dbcff443aa/ this driver.Currently this camera gives image in RGB565 format ans we are converting it...

Storing small data in internal flash

HI, we are working on STM32H750. in our program, we need to store 5 bytes in the internal flash. this data will be read everytime the device is powered on. the data will be changed whenever the settings are changed by the user. i.e. once in a while.M...
