+/*
+ * This program is a modified version of the "hid_test" application by Wayne Roberts. All credits go
+ * to Wayne for writing it, I just did some minor modiciations!
+ *
+ * The program was tested with the FRDM-KL25Z board, with a Modtronix inAir9 SX1276 board mounted in
+ * a Modtronix SHD3I shield. The inAir9 module is mounted in iMod port 3 of the SHD3I module. The
+ * SHD3I shield is mounted on the FRDM-KL25Z board.
+ * It enables the use of the Semtech "SX1276 Starter Kit A" application to be used with this board. 
+ * At the time of writing this, this app was available on Semtech's SX1276 page, in the "Docs & Resources"
+ * tab, via the link "PC GUI (1.0.0Beta5)".
+ * This app can be used for sending and receiving data via the SX1276. To use it:
+ * - Plug the FRDM-KL25Z into the PC via the USB marked "USB KL25Z"
+ * - Start Semtech "SX1276 Starter Kit A" app on PC
+ * - App should connect to board, enabling it to control board.
+ *
+ * ========== Firmware for KL25Z ==========
+ * The default firmware listed on mbed.org puts a clock pulse on pin A5. To fix this, use alternative
+ * firmware (or unsolder resistor R24).
+ * - Download "OpenSDA Firmware" from http://www.pemicro.com/opensda/
+ * - Put KL25Z into bootloader mode (hold down button while plugging in SDA USB).
+ * - Drag "MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA" file onto it.
+ * - Reset KL25Z.
+ * - If the USB drivers do not automatically install, download and run "Windows USB Drivers" from
+ *   www.pemicro.com/opensda. After this, when you plug in the KL25Z next time, all drivers should
+ *   install correctly.
