modtronix H
Terminal for sending and receiving data via Semtech SX1276 chip. It uses the FRDM-KL25Z board, with a Modtronix inAir9 SX1276 board, and 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.
Dependencies: SX127x_modtronix mbed

/*
* http://mbed.org/handbook/mbed-FRDM-KL25Z
+ *
+ * The program was tested with the FRDM-KL25Z board, with a Modtronix inAir9 SX1276 board mounted in
+ * a Modtronix SHD3I daughter board(iMod3).
+ *
+ * MODTRONIX Notes
+ * Use this app to test LORA modem.
+ * - Connect to FRDM-KL25Z, with inAIR9 connected to it (via SHD3I daughter board)
+ * - Connect to PC via USB
+ * - Start HyperTerminal on PC, at 57.6K baud
+ * - Various commands can now be executed on terminal. Use '?' for list of commands.
+ * - Use '.' to see current settings.
+ *
+ * For example, to send test message:
+ * - Select mode in HyperTerminal. For example, type "t1" to configure for bw=250khz, sf=12, payload=9
+ * - Ensure CRC and "low datarate optimize" has correct setting.
+ * - Press "t" in terminal to send a "semtech starter kit" 9 byte message
+ *
+ * NOTE! Ensure "low datarate optimize" is same! In hyperTerminal "ld0" turns it off, and "ld1" turns it on.
+ *
+ * ========== 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.
