Getting real time ADC data out of STPM32

Apart from the V_RMS, I_RMS, power and energy (all aggregated), is it possible to output the ADC readings real time over SPI? I am looking to get 8k samples of I and V out of it. As of it was a pure ADC, with the filtering, but without the calculatio...

Resolved! What should I do with STPMIC1 unused pins ?

Hello,I'm designing a board based on STM32MP1 and we decided to use the STPMIC1A to manage the power. The board is really simple and so we use only the bucks (1 for core, 2 for ddr, 3 for vdd and 4 for extra 3.3). All others (LDOs; boost and switches...

How can avoid overlapping of pwm from different channels?

I am writing a simple 6 step bldc motor control using Hall sensor(Complementary PWM).When I try to switch the pwm(example when HALL input changes from 110 to 101) channel 1 and channel 2 gets over lap.I have inserted Deadtime.One in red is channel 1...

Modifying the voltage setting for one of the voltage regulators in the PMIC entry in the device tree causes the boot up to fail.

hi,we are going to use the STPMIC1E in our design but bc the part is not available we are going to use the STPMIC1B for the initial boards we produce and then change to the desired part.however, the buck4 regulator needs to be changed to 1.2 volts fr...
