|
* CDVRPTRV1Controller - Driver for DV-RPTR V1 boards via serial (USB CDC-ACM, 115200 baud).
|
|
*
|
|
* Uses the same DVRPTR binary framing protocol as CDVMegaController:
|
|
* [0xD0] [len_lo] [len_hi] [type] [txCounter] [pktCounter] [payload...] [cksum]
|
|
*
|
|
* Hardware-specific parameters passed to SET_CONFIG (physical layer):
|
|
* channel - selects which of the two physical input channels to use (bit 0x04
|
|
* in the config byte). Some V1 boards have two discriminator inputs.
|
|
* modLevel - output modulation level, 0-100%, scaled to 0-255 in the wire frame.
|
|
* Sets the DAC drive level for the TX audio path.
|
|
* txDelay - PTT-to-data delay in milliseconds (little-endian uint16_t in frame).
|
|
* Allows time for the radio to reach full output power before
|
|
* transmitting the D-Star preamble.
|
|
*
|
|
* Reconnection and sysfs path tracking work identically to CDVMegaController.
