Need help with example code. I'm trying to do simultaneous ADC sampling on 3 analog inputs at 80KHz for 80 samples. Like to kickoff sampling on trigger from analog comparator. DMA samples to buffer and interrupt when buffer is full.
Thinking STM32G7474xx wound be a good fit but not sure. Need M4 CPU with FPU and low power modes. Like to have MCU in low power mode until buffer full. Any help would be greatly appreciated! I am new to ST MCU tools and not sure even where to begin....
which JSON library is good for generating and parsing for ST Micro controllers
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...
STM32L476 wakeup flag not set when exit from shutdown after JLink removed
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...
Can I use DMA1 in Memory-to-peripheral mode to transfer a data over USART2?
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...
How do I connect the STM32blue pill to two independent power sources?
The setup currently is a connection to a lithium cell and the other is to a solar charger output.
Resolved! STM32F030 Receiving UART Data Only Once
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...
SPI write read is not done properly
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 ...
Resolved! DMA LPUART work only once when power on
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 ...
Need help in reading data from a pressure sensor
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 ...
