/* LEDs
|
|
*
|
|
* The launchpad has several LEDs:
|
|
*
|
|
* - LEd D1 (white) that connects to the USB +5V supply,
|
|
* - LED D10 (red) that connects to the TMS570's NERROR pin,
|
|
* - D5 (blue), D6 (blue), and D8 (blue) connect to the XDS100 FT2322,
|
|
* - D7 (blue) connects to the XSD100 CPLD, and
|
|
* - Two white, user LEDs labeled D12 that connects to the NHET08
|
|
* pin and D11 that connects to GIOA2.
|
|
*
|
|
* NHET08 is one of 32 N2HET pins than can be available to the user if not
|
|
* used by N2HET. This implementation, however, uses only the single LED
|
|
* driven by GIOA2. That LED is tied to ground and illuminated with a high
|
|
* level output value.

/* Buttons
|
|
*
|
|
* The launchpad has three mechanical buttons. Two of these are reset
|
|
* buttons: One button is labeled PORRST performs a power-on reset and one
|
|
* labeled RST performs an MCU reset. Only one button is available for
|
|
* general software usage. That button is labeled GIOA7 and is, obviously,
|
|
* sensed on GIOA7.
|
|
*
|
|
* GIOA7 is tied to ground, but will be pulled high if the GIOA7 button is
|
|
* depressed.
