Rodger Clarke's Zumspot Build

# Building instructions

This is a detailed guide for building the firmware of MMDVM_HS from the source 
code. For quick instructions, please see [README.md](README.md). This software 
runs on STM32F103 microcontroller. Also, Arduino with 3.3 V I/O (Arduino Due 
and Zero) and Teensy (3.1, 3.2, 3.5 or 3.6) are supported. You can build this 
code using Arduino IDE with Roger Clark's 
[STM32duino](https://github.com/rogerclarkmelbourne/Arduino_STM32/tree/ZUMspot) 
package, or using command line tools with ARM GCC tools. The preferred method 
under Windows is using STM32duino, and under Linux or macOS (command line) is 
using [STM32F10X_Lib](https://github.com/juribeparada/STM32F10X_Lib).

    PIN_LED       13
    PIN_DEB       23

You could install a serie resistor (10 - 100 ohms) in each TxRxData and TxRxCLK 
lines, for reducing EMI.

# Hidden functions

You could enable two test modes, if you edit ADF7021.h file before compilation. 
Please always comment these two #defines for normal operation.

- #define TEST_DAC: Enable SWD pin to access the demodulator output signal. See 
application note AN-852 and ADF7021 datasheet, page 60.

- #define TEST_TX: Transmit the carrier frequency. This works only with D-Star 
mode enabled in MMDVM.ini. This test mode will transmit the carrier frequency 
defined with TXFrequency in MMDVM.ini. This could be useful to determine the 
frequency offset of your ZUMspot (with test equipment).

Also in ADF7021.h:

- #define ADF7021_N_VER: enable support for narrow band version of ADF7021 
(ADF7021N). Disabled by default, in general all boards will have just ADF7021.

- #define ADF7021_ENABLE_4FSK_AFC: enable AFC support for DMR, YSF and P25. 
This is experimental, depending on your frequency offset this option will 
improve or not your BER reception.

- #define ADF7021_AFC_POS: enable this option if you can not receive any signal 
after enable the ADF7021_ENABLE_4FSK_AFC option.

- #define ADF7021_DISABLE_RC_4FSK: disable TX Raised Cosine filter for 4FSK 
modulation in ADF7021. Default TX pulse shaping filter for 4FSK is not optimum 
for DMR, YSF and P25. Activating this option might improve audio in 4FSK 
digital modes.

In Globals.h:

- #define BIDIR_DATA_PIN: enable Standard TX/RX Data Interface of ADF7021 
(enabled by default, needed for scanning mode detection feature).

In IOSTM.cpp:

- #define PI_HAT_7021_REV_02: enable pinouts for first revision of ZUMspot RPi. 
In general is not used.
