Hi all!,I have 2 STM32F103C8T6 connected by CAN bus.Each STM32F103C8T6 has the same firmware.This firmware starts sending a message "RequestID" by the CAN bus.Is there a way to avoid send the "RequestID" in case another "RequestID" were detected on t...
Hello,I am currently working to get CAN transmission to work on a STM32F072B-DISCO. I am continuously getting a BIT_DOMINANT_ERROR in the LEC of the CAN_ESR when attempting to transmit. I am using a TCAN1044 (https://www.ti.com/lit/ds/symlink/tcan104...
I lost debug messages from my LoraWAN end device. I made some changes using MX on my project, and this way, I lost debug messages displayed on a serial wire monitor (for example, on Arduino serial monitor). I think it was the cause of this problem. N...
I've taken a look at AN5105 (Getting started with touch sensing control on STM32 microcontrollers) where they present a list with microcontrollers that support capsense:STM32F0 seriesSTM32F3 seriesSTM32L0 seriesSTM32L1 seriesSTM32L4 seriesSTM32L4+ se...
Hi,The RTC block was driven by LSI (internal RC osillator), we just found few boards failed to initialize the RTC block and the program was stuck there. What could be the possible reason? Is it due to the floating pin of Tamper?thanks,Qi
hello I today trying can communication loopback mode working but normal mode bit LEC register showing timing error.
We just found few boards failed UART communication. The debug process for this issue points to the LSI and RTC block inside the MCU STM32F401RET6. The RTC block was driven by LSI (internal RC oscillator), these boards failed to initialize the RTC blo...
Hello, I am trying to establish standard CAN communication between the sn65hvd230 IC and the stm32f4 discovery and stm32f103. While the loopback mode works fine, when it sends data to the normal mode, the output goes to 0 and then back to 1. I still ...
I'm using a STM32L432KC Nucleo board, and reading a voltage with the 12-bit ADC. On this board the ADC Vref is connected to the board 3.3V, which in this case actually measures 3.315 V. With a 12-bit resolution, I would expect that 4095 ADC counts =...
Hello everyone! BackgroundWe are working on STM32G474VET6 based custom board for some specific motor control application. Project demands to have a custom bootloader on FD-CAN with 500kbit/s arbitration baudrate and data rate with 2Mbit/s with BRS op...
