[beagleboard] RE: Analog input sampling rate

Hello, Using libpruio, may I ask if there is any support for reading an I2C sensor via the PRU – or any suggestion on how this can be done? The idea is to read an I2C accelerometer in determined intevals, using the PRU, at 1kHz +. Thanks a lot! Best regards, Istvan

Hi Istvan! There's no I2C support in libpruio and it isn't planed to get implemented, sorry. 1 kHz should be possible to realize on ARM. (For hard real-time requirements use the second PRU.) Regards Am Montag, 14. August 2017 11:36:07 UTC+2 schrieb Biro Istvan: > >Hello, > > > > Using l

Only 7 input pins (AIN-[0-6]) are connected to header pins. AIN-7 is hard connected to the power supply on the board. I don't know what you mean by analogRead command. The TSC_ADC_SS can sample 8 channels at 200 kHz. You can sample at that speed by using libpruio
