# Development Setup
|
|
|
|
|
The development setup is using a LattePanda 3. It is an Intel
|
|
|
|
|
based board with an Arduino Leonardo built on board.
|
|
|
|
|
|
|
|
|
|
This should be similar to using other Arduino devices plugged
|
|
|
|
|
into USB ports.

# Pins

|
|
|
Not all cables have the same color pin out. In fact, most have different
|
|
|
|
|
pinouts, so each cable should be tested.
|
|
|
|
|
|
2023-03-25 11:02:38 -06:00
|
|
|
Note: colors may be different on different cables!
|
|
|
|
|
Each cable pinout needs to be tested or the MP101 can get fried.

# Wire Harness
|
|
|
|
|
I made a quick and dirty wire harness that works.
|
|
|
|
|
My MP101 kit came with two extension cables.
|
|
|
|
|
I used one of those to use the male headed to plug
|
|
|
|
|
into the MP101, and the newly cut wires to connect
|
|
|
|
|
to pins to plug into the Panda Arduino.
|
|
|
|
|
I had short jumper wires with pin headers on each end.
|
|
|
|
|
For the Panda male/male wire with headers is needed.
|
|
|
|
|
If the board being used has pins not headers, a male/female
|
|
|
|
|
wire jumper will be needed.
|
|
|
|
|
In lieu of connecting the pins to the wires via soldering,
|
|
|
|
|
WAGO crimpers were used. They work great and easy++.

# Misc
|
|
|
|
|
Notes.
|
|
|
|
|
|
|
|
|
|
* LattePanda3 docs say their Arduino Leonardo files are needed.
|
|
|
|
|
|
|
|
|
|
* The LattePanda3 Arduino Leonardo files are old.
|
|
|
|
|
|
|
|
|
|
* I can't get the LattePanda3 Arduino Leonardo files to work.
|
|
|
|
|
|
|
|
|
|
* The Arduino Leonardo files in Arduino 2.0.4 appear to work fine
|
|
|
|
|
with the LattePanda3 Leonardo. XXX

# Status
|
|
|
|
|
Early alpha. It moves in four directions, but doesn't stop or
|
|
|
|
|
have regular controls yet. Just mapped out the pins to
|
|
|
|
|
Arduino software.
