| + | ====== More hints ====== | ||
| + | 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. | ||
