Step 2: Make USB connections
The Wireless ARMmite can be connected to SparkFun's USB breakout board. The minimal connection uses a 4 pin 0.1" header. This connection gives a hardwired serial connection for configuration and debugging, which can be useful during the initial setup of the tools and software, or for monitoring serial traffic during program debugging.
Minimal USB connections. The pin diagram is shown below (pin names to match the USB breakout board)
Additional pins may be wired up to the USB breakout board, so that it will work identically with the original ARMmite. In this case 5V from the USB will power the board. But when that connection is made a power supply should NOT be connected.
Below is the schematic with the names representing the perspective of the ARM processor (RXD0 on the ARM connnects to TXD on the USB breakout board).
Shown below is the orientation with the USB breakout board mounted on the ARMmite, using a 4 pin receptacle soldered into the breakout board-
BASICtools Configuration
While you are not using a wireless connection, if you are using just the 4 pin connection to the USB breakout board, the Wireless ARMmite is functioning in "Wireless" mode as there is no control from the PC for reset. So for BASICtools to function correctly you must enable the Wireless option shown below.
