| /* LED Configuration ********************************************************/ |
| |
| /* The Mikroelektronika PIC32MX7 MMB has 3 user LEDs labelled LED0-2 in the |
| * schematics: |
| * |
| * --- ----- -------------------------------------------------------------- |
| * PIN Board Notes |
| * --- ----- -------------------------------------------------------------- |
| * RA0 LED0 Pulled-up, low value illuminates |
| * RA1 LED1 Pulled-up, low value illuminates |
| * RD9 LED2 Pulled-up, low value illuminates |
| * RA9 LED4 Not available for general use*, indicates MMC/SD activity |
| * --- LED5 Not controllable by software, indicates power-on |
| * |
| * * RA9 is also the SD chip select. It will illuminate whenever the SD card |
| * is selected. If SD is not used, then LED4 could also be used as a user- |
| * controlled LED. |
| * |
| * If CONFIG_ARCH_LEDS is defined, then NuttX will control these LEDs as |
| * follows: |
| * ON OFF |
| * ------------------------- ---- ---- ---- ---- ---- ---- |
| * LED0 LED1 LED2 LED0 LED1 LED2 |
| * ------------------------- ---- ---- ---- ---- ---- ---- |
| * LED_STARTED 0 OFF OFF OFF --- --- --- |
| * LED_HEAPALLOCATE 1 ON OFF N/C --- --- --- |
| * LED_IRQSENABLED 2 OFF ON N/C --- --- --- |
| * LED_STACKCREATED 3 ON ON N/C --- --- --- |
| * LED_INIRQ 4 N/C N/C ON N/C N/C OFF |
| * LED_SIGNAL 4 N/C N/C ON N/C N/C OFF |
| * LED_ASSERTION 4 N/C N/C ON N/C N/C OFF |
| * LED_PANIC 5 ON N/C N/C OFF N/C N/C |
