STM320L0 I2C timing issue?

I'm working on a board with a STM32L010K.For some reason, I can't get the I2C code to work properly. I mean it works (data gets read from the slave) but not if a lot of things are done in succession, then a hard fault is thrown.Below is the block rea...

The strange GPIO pullup output voltage

I tried 3 boards F407vet6 x2 and F427 x1.I found both pullup and pulldown gpio output in PP and OD will put a low voltage. 20mV in down and 50 mv in up.This situation is based on the stdperiph-LibHowever, use the Hal-Lib to implement the gpio output,...

STM32H7 USB Audio as USB device class

Hi everyone,in my latest PRJ, i had to run some arbitrary waveforms. The idea was to connect my STM32H7 to the host and configure it as USB audio device. As far as good...the problem is that i had to drive 60kSps (16Bit). So since i've read on the X-...

Internal JTAG on STM32

Hello all together! Does anybody know if an internal JTAG device is integrated on the STM32H562 oder STM32H563?In my case, I need to implement the functionality to flash an external microcontroller over the STM32 chip itself.That would mean, I have a...

Low power on STM32L4 series using RTOS

I've been trying to implement low power modes on an STM32 L496 (Nucleo board) while using RTOS. I've tried with both freeRTOS and ThreadX. I followed official ST articles/tutorials and the lowest I got so far has been ~250 uA.  So, has anyone been ab...
