Hi , I m a student starting to learn STM32 for your final year project i would like to learn more about how to use FreeRTOS, using STM32CUBEIDE GUI to configure FreeRTOS and if anyone can advise any website, code , tutorial I can learn from? thx.
Resolved! External DAC with SPI + DMA
HiI am trying to make an analog synthesizer, and for this is using a STM32G431 with some 8-channel DAC’s (connected via SPI) for generating control-voltages for the VCA’s and other circuits.I would like to use the SPI with DMA, and have looked at the...
Resolved! Input signal when MCU is powered off
Hello,I will make some probes for reading electrical values (AC, Analog, digital,...), but I'm not sure what happens if I insert a signal to a GPIO when MCU is powered off.I read time ago that all GPIOs are in high impedance state when MCU is not pow...
