SUMP protocol implementation for Arduino.
Hardware
- Main chip: Atmel ATmega168/328/2560
- Input pins: With optional internal pullups (currently has to be modified at compile-time)
- 3.3V and 5V output: 3.3V, 5V
- 16MHz crystal: 16.000
Note that some older arduino designs and arduino clones feature FTDI usb-serial chip, which might be used as logic analyzer as well: [FTDI-LA]

Protocol
- This uses the extended SUMP protocol as implemented by sigrok in ols driver.
