I sample a 1000Hz periodic signal twice each period. At 50us after the start of the period for samples A and after 850us for samples B with a single ADC and a single channel. I trigger the ADC with a delayed PWM (Combined PWM1 on a G431) and the res...

I see G4 as successor of L4 for demanding applications, but I noticed DFSDM that is available on many L4s is not available on G4. Out of curiosity: is there a reason for it? Is there a replacement technique I might not be aware of?thanks!

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...

I thought I ran into a bug when CubeMX could not configure oversampling for an F767 after I had used it on the less powerful L4. Read the reference manual and understand it is not there. Could not find which non-L families DO have oversampling. Hence...

2D buffer works. Thanks!

AScha.3, thanks, that helps me in my thinking of part of the problem. I will refrain from stopping DMA. And you are right: Stopping/stopping the PWM trigger doesn’t matter: rising and falling edges will always alternate perfectly. Hence the DMA will ...

Interesting and hadn’t thought that that is possible of course. Makes coding easier. But still I want it to be super explicit that A’s are rising edge and B falling edge samples. I stop and start the PWM triggers now and then and do not want to risk ...

Anybody?

@Vkamm.1I had no problem at the end. I successfully connected. But not sure what was the “break thru�?. The root CA, AWS policy, correct date on the IOTA boarde (certificates do not work with random dates), string format of the keys in the C code?Adv...

Two DMA buffers for alternate ADC samples on the same pin

Is there a reason DFSDM (sigma delta interface) is on L4 but not G4

Getting real time ADC data out of STPM32

What families have oversampling on the ADC(s)?
