MMDVM_HS_Dual_Hat

Duplex variant of MMDVM_HS_Hat beta DB9MAT DF2ET DO7EN

This PCB uses the MMDVM_HS by Andy CA6JAU. It has two ADF7021 onboard and allows for duplex operation with two time slots on DMR.

A beta version is currently under test.

MMDVM_HS_Dual_Hat

BOM

Mouser cart for rev0.1 is here.

Firmware installation

Compile and upload manually

For specific details about the firmware installation, check these instructions. The process is similar to the installation on the ZumSpot Pi.

Enable the following settings in Config.h:

#define MMDVM_HS_HAT_REV12
#define ENABLE_ADF7021
#define DUPLEX
#define ADF7021_14_7456
#define STM32_USART1_HOST
#define ENABLE_SCAN_MODE

Optionally:

#define SEND_RSSI_DATA
#define SERIAL_REPEATE

Build the firmware:

make

And finally upload the firmware to the MMDVM_HS_Dual_Hat:

sudo make mmdvm_hs_hat

Update within Pi-Star

Currently not possible. Will probably follow.
