Hello everyone i am building project which is use to monitor the room temperature and humidity and CO2 level but i want send this data into JSON format to web server but i didn't find the any library that generate and parse data for stm32 micro cont...
I have a project that makes use of the two external wakeup pins, and need to know which pin woke up the device. After flashing, with a JLink, the board can enter/exit shutdown, and will set the correct wakeup flag in the PWR_SR1 register.If I power c...
I'm lerning Cortex-M7 (stm32f722) and I don't fully understand how DMA1 works. On the one side DMA1 not connected with AHB therefore PORTs and SRAM not available. On the other side in datasheet didn't type that Peripheral-to-memory and Memory-to-peri...
The setup currently is a connection to a lithium cell and the other is to a solar charger output.
Hello,I'm trying to send data to STM32 from NodeMCU. My project is simply controlling WS2812B LEDs by using SPI from STM32 and receiving commands by using UART to STM32 from NodeMCU. LED's working fine by SPI but I can only receive data once at start...
Hello,I am working on STM32h7 controller. I configure the AD9106 DAC to SPI. When I tried to write read the configuration register some some registers are get read write and some not why these happening I check the register they are read write able ...
Hello everyone,I work on a project with STM32L072CBT6.I want to use a DMA RX on LPUART1, after reading differents ressources i have setup my LPUART and my DMA.I want to receive an interrupt from my DMA when transmit IDLE (end of transmit).My problem ...
Hi!I'm new to embedded programming and I'm trying to write a minimal program using I2C to read data from a pressure sensor.I'm using the STM32F429 board and the Sen-16476 Sparkfun pressure sensor.I'm unsure about which pins I need to connect between ...
Hello folks,I have an issue with STM32L051C8T6 - processor halt always on HAL_RCC_ClockConfig verification and have no idea where it's coming from.I made a simple blink project with only two lines of code as a new CubeIDE project (all defaults) with ...
Hello,Would you please double check are those low power types STM32Lxx affected by PCN# MDG/22/1364 as attached?In PCN only general purpose types STM32G070xx, STM32G071xx and STM32G081xx listed:In attachment “Public Product List�? low power types hav...
