Hello,I'm trying to port a library written for STM32F413 to another device of the family, the STM32F407. The library depends heavily on the Flash HAL module driver, which I have never used before in any of my projects. The driver for the STM32F4...
Hi guys, does anyone draw a circuit to get the stm32F4 MCU with USB connector working properly . Thanks
I'm still very new to STM32 processors, and using CubeMX to generate my basic code structure (for TrueStudio). In the code below, if I uncomment code section A, the yellow LED blinks, but not evenly... At low values such HAL_Delay(100), the high time...
I'm still trying to get FatFs to work with 4 wires. My PCB has been properly traced, each line is within a few mm of all others, and has a 33K pull-up. Internal pull-ups are off.This setup works fine at full-speed (45 MHz) when using only 1 wire, b...
