Resolved! STM32 custom board with stlink binary
Hi, We want to incorporate the STLink firmware binary provided by STMicroelectronics here onto our custom STM32 board with stlink circuit. However, we would like to seek clarification on whether this usage would allow us to sell our custom board comm...
Determine GPIO State: PWM or High or Low - changing state
Hi, forgive the newby question, but I'm a newby to STM and micros in general. I'm a hardware engineer and have not really ventured too far into the code world until now.I need to monitor 4 GPIOs. They could be any of 3 states: PWM (~50% duty, 1 secon...
STM32H7 and openbootloader
Hi I'm implementing Openbootloader to my project, using an STM32H743, and is having a hard time finding the correct start addresses and size for "Option bytes registers". This is needed to in the "openbootloader_conf.h" file in the Openbootloader mid...
STM32L151VE ADC
"The ADC of STM32L151VE is not functioning properly. The output values of the ADC appear to be random. Does anyone know how to resolve this issue?
STM32F4. Transfert data from SPI3 to SPI1 and DMA ?
Hello,I need with STM32F4 to read datas (multiple bytes) from a sensor connected to SPI3 and transfert the bytes i read from this SPI3 to an external memory connected to SPI1.I would like to use DMA (if possible). Seemingly SPI1 can only be connected...
Resolved! How to measure power supply internally on STM32F107?
Hello community, I'm working on a STM32F107VCT6 where I have practically (by means of very basic filtering) shorted on the PCB VDD/VDDA/VREF+/VBAT and VSS/VSSA/VREF-. I've runned out of pins so I was wondering if there were a way to measure the pow...
Resolved! Help in selecting a dev board
I have over 25 years in embedded design but I am new to ST and ARM cores. I am looking at the STM32 MCU's to replace a 32bit MCU I am already using, the only feature I don't need is the graphics system as we have our own GUI hardware and firmware. I ...
Resolved! FLASH ECC Codes Cause Bus Fault on STM32H743
Hello,For a few months now I have been having issues with writing data to flash memory on the STM32H743ZIT6. Most of the time, everything works great and I am able to read the data from flash successfully, but every now and again, the flash memory ge...
STM32L4R9I_EVAL and TouchGFX EEPROM issue
I'm using the STM32L4R9I_Eval board with the STM32 Cube IDE (v 1.12.1) and the TouchGFX interface (v 4.21.3). I'm having an issue with EEPROM... I grabbed the STM32 provided BSP EEPROM code and am basically reading/writing a structure that contains ...
