the above connector is actually numbered so it should be easier to determine
|
||
where the needed connections are.
|
||
|
||
to connect to the teensy, the following are pins are needed (if you should choose not set your own):
|
||
* PB0 -> PB6 are connected to D0 -> D6
|
||
* +5V is connected to the corresponding teensy pin
|
||
* gnd is as well, only one of the gnd pins needs to be connected though.
|
||
* strobe is connected to pin PD1
|
||
* data is connected to PD0
|
||
* PE does not need to be connected to anything, but it could also be connected to gnd
