Hello, I am working with my custom PCB with STM32L053R8T6. My code works just fine when I run it in debug without any stop mode (deep sleep). It enters to the RTC and button interrupts perfectly. However, when I want to make the MCU enter to sleep mo...
Hello,at the moment i try to verify the conversion time of the ADC that is described in the datasheet.I measure one channel in regular conversion mode without interrupt. To calculate the conversion time i used the equation in the datasheet.Tconversio...
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...
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...
