Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I'm creating a CANopen protocol, but I'm having a problem with the code. I used two while loops, and as far as I understand, this is preventing me from seeing the data I'm getting from the sensor in the 'live expression' section. Do you have any sugg...
Hello,I'm working on a project where, per SPI channel, I need to:Read voltage from four AD4630, 2x6 bytes read and 2x3 bytes read.Calculate outputSet 4 MAX5719 DAC output 4x3 bytes transferEach of them use separate cs pinI need to handle 3 channels l...
I'm using STM32F429 and trying to read the internal temperature sensor and convert it to a degree C value. Absolute accuracy is not important right now, I just want to make sure a reasonable representation of temperature is being produced. The ADC is...
Hi, I'm have a trouble with UART Interrupt when using FreeRTOS.I want to receive a string buffer send from Serial Terminal ( Hercules Software ) using UART interrupt mode. But when I send data, I just receive 2 character. Ex: When I send "Resume", I ...
Many small format LCD displays do not provide parallel RGB interfaces but instead rely on high-speed serial interfaces such as QSPI. To support this class of display is it possible to use the XSPI peripheral in QSPI mode to drive them? An example LCD...

Hello, I saw the thread below and now a bit confusedhttps://community.st.com/t5/stm32-mcus-embedded-software/update-about-usb-pd-stack-to-support-epr-mode/td-p/829168It says EPR is supported with a TCPP package but the TCPP-M18 itself - rated to 100W...
I want to calculate the resistance/power of an AC heating element by measuring voltage (via a voltage divider) and current (using an ACS71240 current sensor). The hardware setup is fine. I get the expected values. I checked this when using Arduino Fr...
This example work perfectly using non interrupt driven UART HAL library, HAL_UART_Receive and HAL_UART_TransmitAny idea on changing to HAL_UART_Receive_IT and HAL_UART_Transmit_IT?Many thanks https://forum.digikey.com/t/easily-use-scanf-on-stm32/2110...
I'm trying to make audio equipment using stm32f446re board and pcm5102 module. When I used the audio equipment, when I sent music using i2s communication, the output came out well, but when I finished DMA setting after selecting i2s protocol in sai, ...
