Good morning,I am working with a board mounting a STM32L0x3 microcontroller. My SystemCoreClock is 32 MHz and TIM12 is clocked at 4 MHz. TIM12 has been configured in order to work in Capture Mode on Channel 1 (falling edge).The ISR does what is liste...

I am experimenting with PWM DMA on STM32F407VET6. The code creates pulses of increasing width.If I enable the output compare preload, the number of pulses is 2 instead of 6.The first pulse at startup is the default setting from the configuration in M...
Hello, I am using an STM32L462 microcontroller with a crystal from Wurth: 830 016 178This crystal has a load capacitance of 6 pFI calculated the two load capacitors CL1 and CL2 to be 4.3 pFNow, everything is working OK, and the RTC is running fine......
I have a B-L475E-IOT01A2 board. I'm trying to use the onboard microphones to record audio, using the DFSDM peripheral, and then send the data over UART to my PC to play it back. The thing is, the data I get is basically just static.Here is how I conf...
For a project, I need to find a stm32 that has a minimum of 5 timers that can read encoders, and it has to have a CAN-bus peripheral.Is there a way to do this in the part selectors? I can select the minimum number of 16bit timers, but not all 16bit c...
We need to make a master PWM that vary duty cycle from 1 to 35% and have a phase shift with two other pwm (this two other pwm are in phase and duty cycle 50%, but one starts with one and other starts wiht zero.). The phase shift should vary from 1 to...
Hello, I have some trouble with FDCAN.Please let me know what is wrong with my settings. 1. Current problem: My STM32H7 transmit only error. (Logic Analyzer) (PCAN View)Same error signal repeat endless and if I connect PCAN, many other error and stuf...
Hi all,I want to drive Humidity and Temperature Sensor SHT4x(address is 0x44).I finished the driver code in STM32F103C8 with HAL lib, but when I used the same driver code in STM32F429IG with HAL lib, the HAL_I2C_Master_Transmit() always returned HAL_...
Hi, Regard I Problemed with stm32h747xi mcu. #Setting - Power mode control is direct smps supply mode - clock 480MHz - VScale0 Setting i saw stm32h7 user manual direct smps supply mode doesn't setting with 480MHzSo now I Know.But I don't know wh...
