I want to communicate with STM32f427 processor and 3 sensors via SPI. I want to use only SPI1 line. I need 3 chip select pins. There are 2 SPI1_NSS pins on the datasheet of the processor. What can I use as 3 CS pins? Is any GPIO pin suitable?
Can any one confirm that STM32G030k8 MCUs can be implemented for DALI-2 lighting.Is the memory works.
Hello, I'm trying to use the stm32u5 585 and I'm having a bad time trying to figure out what I am doing wrong. I am getting about 1.2mA in stop mode 2 when I should be getting around 8.95+ uA.I've disabled all SRAM and everything else in the PWR sect...
I'm looking to know what is the best ST microcontroller that works best for ultra low temprature -80c and liquid nitrogen ?I understand that full functionality is not guaranteed as per the specs. Note: external oscilator will be used as HSE that will...
I'm getting Hard Fault Exception at -40c while using STM32F0412VET. Any idea how to avoid such exception ? setting certain registers or disabling certain peripherals?As well is there sample implementation to return to previous context before the exce...
