Finished the Housing of the B-sample and testet the whole machine. The B-Sample is thus completed and will be disassembled to reuse the parts on the C-Sample.Also made test for the chamfered housing Parts for the C-Sample.
Rev B cage assembled.I'm very happy with how the mechanical integration came together. There are a couple of screw holes that don't line up with the PC case, but the cage is still held firm.Tell me it doesn't look like it came out of a factory.
Wrote a very basic command interface with three commands:W - Write the EEPROMR - Read the EEPROMB - Bounce an LED across the RPP-UIO-16 cardThe result looks like this:Write to the EEPROM Read from the EEPROM 0000 00 01 02 03 04 05 06 07 08 09 0a 0b 0c...
