datasheets
known issues
- EEPROM lacks pull up on EECS
- Need 10K resistor pack for RE2 (has 1k)
- the ISP select should switch the power supply also. eg the ISP is connected to PORT1 power and gnd, but if there is nothing connected - the realice thinks that nothing is connected.
- will need a way to latch the present ISP selection as when the SERIAL port is close, the value can't be changed.
- also want an LED to indicate which port is selected.
ECO
- cut trace to RE2, pin3
- run wire from RE2.3 to UE1.1
serial numbers
- 1 - assembled 10-15-09; tested both isolated serial port; ISP not programed.
- has 1 ISP connector and uses ISP switch
- after addition of EEPROM - doesn't enumerate
- need to re-assembly to use 2 ISP connectors.
- 2 - assembled 10-16-09;
- has 2 ISP connectors.
- after addition of EEPROM - doesn't enumerate
assembly mods
- RE2 will be 10k not 1k
- 4.7uF replaced w/10uF
