Hello,recently I was testing HTTP webserver project on a NUCLEO-F429ZI board and it works ok. I have created a driver for LAN9303 (dual port PHY) tested it using shield based on this https://github.com/ATM-HSW/MbedOS-with-LAN9303After it worked, I su...
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...
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...
