Why I2C pins are always low in STM32F0?
Hello, I have a SMT32F042, i'm trying to use I2C. I used STM32 CubeMX to generale a new blank project with only i2c (see attached). I2C on non standard pins. The problem is that they always stay low, it does not transfer anything.This is what I captu...
Resolved! STM32G070 Startup file
I created a Keil project for STM32G070 without using Cube. It compiles but the link fails with error L6236E which seems to indicate there is no startup file. Can anyone send me a file that will work? In case it matters, the board that I am using is a...
Resolved! IWDG not stopping on debug when CAN Receive interrupt triggered
I'm having a significant problem debugging my board with CAN traffic. Whenever the debugger is paused, and a CAN message is received via interrupt, the independent watchdog is being reset. As far as I can tell, I'm disabling that peripheral on debug ...
Resolved! Why is ADC + DMA not triggered?
Hi! I'm using STM32 F301C8T for my LLC converter project. I have two MOSFETs switching at variable frequencies ranging from 80kHz to 400 kHz. Due to significant noise caused by switching, I need to time the output voltage measurement between the swit...
Resolved! STM32H743ZIT6 random startup problems when D-Cache enabled
Hello,I am about to improve the execution speed of an existing code base on a NUCLEO-H743ZI2 board.So far, I have the following memory setup:Instruction Memory:ITCM for time-critical functionsFLASH (+ I-Cache) for remaining instructionsData Memory:AX...
Resolved! switch from stm32f407 to H753 PWM period halved
Hi,i had a programm running on the stm32f407 and PWM output via Tim2 The timer is configured with clock 84MHz and PWM Counter Period 5040 which gives me a period time of 60us. The timer is clocked via APB1. this works finenow i use an h753 with the ...
