- | I use an [[http://www.fischl.de/usbasp/|USBasp programmer] which I highly recommend. Since the fuses are not set initially, you need to set the SCK jumper (or use avrdude's -B 3 option). I also power the board over the programmer during programming.

+ | What are the LEDs for? | ||
+ | * red: operation | ||
+ | * blue: tx for FTDI | ||
+ | * yellow: rx for FTDI | ||
+ | * green: signal an incoming S0 pluse or "writing to eeprom has finished" (see [[https://github.com/comsound/flukso/blob/master/software/main.c#L160|remark]] in source) | ||
+ | |||
+ | What inputs are there? | ||
+ | * INPUT0: analog input for one split core transducer mentioned above | ||
+ | * INPUT1: analog input for three split core transducers in series | ||
+ | * INPUT2 + INPUT3 + INPUT4: S0 inputs | ||
+ | |||
+ | What about a case? | ||
+ | * The board fits nice into a TEKO A2 case, cutouts for the conectors can be made by cutting two slots into the cover on each side, then the remaining metal is bend to the inner, leaving a stable structure. |
