RTC not working on STM32L073RZ
We have made 500 PCB's with STM32L073RZ and 150 have issue in starting the RTC.We have used the recommended 32.768Khz but its not working for the 150.We have tried changing the recommended 32.768Khz with the cylindrical crystal it worked but when I t...
Resolved! Pin-compatible layout for STM32F7 and STM32H7 possible?
Hi to all,I am planning a basic STM32 platform PCB for industrial HMI for different customers. At the moment is is not quite clear which microcontroller from STM32F7 or STM32H7 series will be used. It depends on firmware developed by customer. But ha...

Load Capacitance for RTC and Primary oscillator for STM32G474QET6U
Hi all,I was looking at STM32G474E-EVAL's schematic and upon inspection of the load capacitance of the RTC and Primary oscillators it seems that the capacitor values chosen were 4.3pF and 1.8pF respectively. However the datasheet for the crystals sh...
Serial programming STM32F446 using ESP32-Wroom
The question gives away most of what I am trying to accomplish. I got a project for which I need to update the code/firmware and to test what I do. I have a device (PCB with peripherals).How things are connected?I have an ESP32-Wroom which is like th...
Creating custom STM32L072 board and need advice on the SWO pin
I have a custom STM32L072 board I developed and I'm trying to understand the ST-Link/SWD pin layout. Looking at the Discovery board schematics I was able to determine which pins to use for the SWCLK, and SWDIO pins, but there is some confusion on the...
STLINK-V3 bridge driver
Hi there,Is it possible to get the sources of libSTLinkUSBDriver.so ?I would like to build a FreeBSD native binary.This is the only missing element in the bridge code sample.Thanks.
Resolved! Can't get the ST-Link-routed USART communication to work on the STM32F767ZI
I'm trying to print output to the console in the STM32 work bench, but I can't seem to get anything out, and with my lack of a logic analyzer the best I can do is confirm my calls to HAL_UART_Transmit return HAL_OK. Below is the minimal example I'm a...
