I think this is off-topic, but I was thinking in the following configuration for some projects:
- Raspberry PI computer - A custom made SPI card with 4 DAC and 4 encoder input DAC: http://ww1.microchip.com/downloads/en/devicedoc/21897a.pdf Encoder: http://www.anaheimautomation.com/products/ics/lsi-csi-item.php?sID=270&serID=17&pt=i&tID=159&cID=55 - Four analog motor driver, maybe: www.logosolinc.com I hope some electronics guru encouraged to build the configuration B card, and its HAL driver.
