Is it OK to tie NRST lines together for 2 or moreSTM32F042 processors ?

Is it OK to tie NRST lines together for 2 or more processors ?In this case, they are STM32F042C6T6I would think so but just thought I'd ask.boB

Resolved! Strange behaviour with STM32G474QE pin PB4

I use pin PB4 on STM32G474QE as normal GPIO output. The external load is ~20kOhm to GND.There is a strange behaviour after reset without any further initialization:1. It seems to be an internal pullup <10kOhm that drives the output to high2. Another ...

STM32H7x3I-EVAL2 board: free pins on the I/O extender (MFX)?

I need to hook few external signals to STM32H7x3I-EVAL rev. E, if possible without soldering or losing access to FMC, QSPI memories.This board is much busier than Nucleo, I can find only few free pins on the default pinout.The user manual (UM2198 rev...

Resolved! STM32H750VBT6 & CubeMX & IAR

Hi everyone ;I am having a strange issue with IAR . I configured the mcu via cubemx and generated it then I build all the files but I got the errors in the attached files when I try to download the code into the MCU . But I don't get any issuse with...

Possible bug in HAL quadrature encoder implementation

HIWe bought a AMT102-V encoder from CUI devices. It is a 1024 pulses per rev encoder.We are using a STM32H745 nucleo board and the HAL library with inbuilt pulse detection for quadrature encoders. Code is being run on the CM7 core.Every pulse increm...

STM32F105RCT6 vs GD32F105RCT6

HiDue to a shortage of STM32F105RCT6 we need to use the GD32F105RCT6. So a firmware that is running on the ST MCU needs now to run on the GD MCU. Does anyone know if the GD32F105RCT6 is fully compatible with the STM32F105RCT6?Not just the pinout but ...

PWM Output on STM32F031C6TX

HI all,Does anyone know how to configure the One Pulse mode on this chip using the HAL library?I tried producing a constantly on-pulse on a timer by setting the CCR value to be greater than the ARR value. And it produced no outputP.S: I accounted for...

STM32F767GTx custom board with webserver (LWIP and HTTPD): webpage don't refresh

Hi,I'm a french embedded developer.At my office, i use a STM32F767GTx custom board with a N25Q128A QSPI Flash memory. I have some CSV files on my flash memory, generated by the software.I've coded a WebServer using LWIP and HTTPD with multiple pages....

STM32F756ZGY6TR GPIO READ ERROR on PORT A Pin11 But Same Code Works fine on STM32F746IGT6

Hi, We had to change to a new MCU from the same family due to the great chip shortage of 2021.But on the new MCU STM32F756ZGY6TR.PORT A PIN11 does not read its state propertyPORT A PIN10 works fine thoughPIn11 will read low (correct) but then on ne...

QSPI becomes endless busy after programming 1 page of external memory

Hi everyone!My goal is to program big-sized data into external memory (MICRON). But I have very annoying problem. I can program only 1 page of ext. memory (256 bytes), I use DMA (mem to periph) to read data from buffer and send it to QSPI data regist...
