I am trying to configure STM32 Nucleo-64 G070RB Board as Modbus RTU Master to send commands to a slave and receive response. I have connected MAX485 - TTL to RS485 board. Powered with 5V, DE and RE connected to USART1 DE Pin. Board's A and B are conn...
Hi, I’m Lalin Prasad. I’m currently learning bare-metal programming using he STM32L433 MCU (STM32L433RCT6PU).While working with I²C communication, I interfaced a sensor successfully, but I’m not getting the correct output values.This is the UART term...
Hi all i have been working with LTDC module inside stm32 MCUs to drive an external parallel 24 bit RGB display , i integrated an LVGL UI inside this project but my output is kinda look like this i dont know what is causing it , . display is running...
Hi all,I am trying to understand the relationship between CCRDY and CHSELR. Unfortunately, there is a bit of bad grammar in the Reference Manual on this subject, which is not helping...The manual seems to say (and some examples support this) the sequ...
Hi,I changed the MCU on my design from STM32 L031 to L051 & L052 to have more flash then have a DAC output.I kept exactly the same ST supplied libraries / APIs for the RFID part, and command them in the exact same way with all MCUs.SPI to RFID chip r...
Hello,We are using STM32U375xx/85xx MCUs and want to implement firmware update over UART using another MCU (ESP32-S3) in out application.The ESP32 will send the .bin firmware to the STM32 without using any ST utility (e.g., CubeProgrammer).From the S...
Hi,I am trying to add FreeRTOS to my project.Board = Nucleo-U5A5ZJ-QTrustzone = enabledFreeRTOS = in non-secure project I have Trustzone enabled, therefore a secure and a non-secure project is generated by CubeMX. I added FreeRTOS in the non-secure ...
Hello All,I am working on STM32H747I-EVAL for one of the application development where I am using the uart for communication. I am using UART2 with below pins for my commands and response communication with interrupt mode on 115200 baudrate. PA2 ...
I am trying to implement peak current mode using STM32G474. I implemented the code using direct register manipulation for high-speed interrupt operation. I confirmed that a sawtooth wave is generated using the following code, and that variables can b...
I am developing I2S on the NUCLEO-L433RC-P development board using a BT401 bluetooth audio receiver and MAX98357A I2S amplifier.I need to pass the I2S audio data through the STM32L4333 (refer to diagram below). I have done this before using a Microc...
