But typically only 8 bit resolution which probably won't work here. I would be tempted to try an ADS1256 board. https://www.ebay.co.uk/itm/194241659854 I have one of those hooked up to the SPI of an AdaFruit Feather M0 as part of a stalled Faro Arm project. It _should_ be possible to read the SPI data in a HAL component. Somehow. You could use a Mesa firmware with BSPI if the onboard SPI is hard to interface. It looks easy in Python if you don't need realtime. https://raspberrypi-aa.github.io/session3/spi.html -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
