STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Good morning when compiling a project to which I added files (.h and.cpp) returns the error of "undefined reference" on a function that is in these files. I also add that I added other files (always .c and.h) of which I called a function without havi...
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
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 ...
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...
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...
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...
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 ...
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...
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....
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...
