I want to use crc hardware peripheral in STM32U535 for checking some modbus and I copied a code from this community thanks to @Tesla DeLorean . But in my case this code seems to work only for a buffer lenght multiple of four bytes. I can't found my e...
Hi team, We have our own customized USBPD board (STM32L562CET6) which support both SPR(100W) and EPR(140W). SPR is working great, now we want to work on 140W using EPR mode. So that initially we have tried to enter EPR mode by following method #defi...
Below is my main.c file. I'm wanting to scan analog pins PA0 and PA1. They work individually when not using DMA, but when I try to use DMA, the analog values are read once and then never updated after that. Any ideas? /* USER CODE BEGIN Header */ /*...
i'm interfacing ADT7420 with STM32F411. As per datasheet of ADT7420 the i2c specifications are as follows: Table 2. SCL Frequency 0 - 400 kHz SCL High Pulse Width, tHIGH 0.6 μs SCL Low Pulse Width, tLOW 1.3 μs Therefore as per my understanding the ...
I am trying since a couple of days to implement a CAN Bus communication for my above mentioned board without success. I wish to do this using the Registers only. Can someone give some hints on how I should proceed? or a link?. Thanks in advance.

I am using Half-Duplex to network 3 "BluePills" (STM32F103C8). There is one master, and two slaves. The master sends out a request with a slave identifier prefix.The slaves receive all messages from master and all responses from the other slave, an...
I am trying to upload a firmware on an stm32uf board with the CLion IDE. I keep getting the following errors: Info : clock speed 500 kHzInfo : STLINK V2J29S7 (API v2) VID:PID 0483:3748Info : Target voltage: 3.234031Info : [stm32u5x.cpu] Cortex-M33 r0...
I've been trying to connect to multiple OV5640 camera sensors from different brands and even STM32's official board B-CAMS-OMV on the STM32-H7A3ZI-Q nucleo board and have had no luck with it whatsoever. Does ST have any projects that are built off t...
Hello,the reference manual of the STM32G4 Series states, concerning the arbitration of mem2mem transfers:When a channel x is programmed for a block transfer in memory-to-memory mode,re arbitration is considered between each single DMA transfer of thi...
