PWM generation TIM1 CH1N
I am trying to generate a regular PWM signal using TIM1 CH1N on the STM32-F411RE (pin PA7). I've seen a few posts on generating PWM using the advanced timers but nothing has seemed to work. The code below is the automatically generated code called in...
STM32F405 GPIO pin
As shown above picture, I got my STM32F405 configured as open drain to drive the led that is connected.Also, the same pin connected to via hex inverted (74HCS04D) to invert it and connected to OR gate. But when the GPIO pin in reset (low) state volta...
STM32H743IIx DMA from AXI SRAM to external SDRAM not writing all SDRAM addresses correctly.
I wrote a test that uses the DMA2D to transfer 64kB of data from AXI SRAM to an external SDRAM. I set the source data to be all 0xFF and started the DMA. Using the Memory viewer in STM32CubeIDE I see that the SDRAM is getting filled, but there are ...
Resolved! Timer synchronization
Hello Everyone i am using stm32G031J6 Microcontroller. I want to generate a PWM signal from Timer 1 working as slave in gated mode, that has a pulse width = 10us and pulse period = 44us In this microcontroller i am using Timer 3 as a Master which ha...
Ping not work on STM32L475 ETH
Hi, I'm trying to get the ethernet interface to work on an STM32H745. After fixing various hardware problems, now I don't just have software problems.I created a simple project with CubeMX, basically I did these things:- Enabled ethrmnet interfaces- ...
