Im still using the Portenta H7 as well. I need the Portenta for driving an actuator and sense its response in acoustic frequency domain. so i need to use the DAC and ADC in relativly high Sample rates. and send the data via Ethernet to a PC (LabView) to process the data. One channel reading is working fine i achieve a Sampling time of about 6µs per writing DAC and reading ADC.
so far im struggling with DMA for ADC fast multichannel reading. if anyone has a nice little (working) example (at least for 2 channels) i would be very happy
I actuealy like Portenta (very powerfull device), but sometimes the lag of support drives me crazy.
(i mainly use HAL in my Arduino sketch)
