DESCRIPTION: The basic M1 DDS Controller Kit consists of
the EME190 Microcontroller board, EME189 encoder board,
4x4 keypad, 16x2 LCD display, and miscellaneous hardware.
An optional EME187 logic interface module can be connected
to the microcontroller module, to expand the outputs on the
microcontroller for the functions required by the M1 modules.
The original Mini-Kits HF-DDS software is used to control all
the functions required by the M1 Transceiver, and can be
used with either the AD9850/51 or AD9951/54 DDS.
AD9951/54 is recommended for high performance receivers
as the spur level is very low. The AD9850/51 does produce a
few audible high level spurs on spot frequencies that can be
annoying.
SOFTWARE:
The original HF-DDS software was originally
written in 2009 to suit a PIC16F4520 Microcontroller which
allows for future expansion, and the option of using either the
AD9850/51 or 12 bit AD9954 DDS. The circuit design has
changed many times over the years to improve the overall
construction and performance.
based on the Yaesu FT817 Transceiver, and has many of the
control functions that are not used with the M1 Transceiver.
The functions can either be controlled using a rotary encoder
and 4x4 numeric keypad, or by using Ham Radio Deluxe with
CAT commands through an optional FT232R USB to serial
adaptor. Some minor functions which are not used on the M1
are only settable in Ham Radio Deluxe, and are not available
on the keypad or in the LCD menu settings. The PIC Micro-
controller module can be interfaced to an optional M1 logic
interface module for switching of external circuitry normally
associated with a Radio Transceiver including RX/TX power
switching, band switching, modes, and AGC etc.

HARDWARE: Refer to the block diagram for the M1 DDS
Controller.
The hardware consists of a number of module
Boards and components that are connected together using
IDC headers with ribbon cables. This is to avoid wiring mis-
takes and makes it much easier to interconnect to other cir-
cuitry without requiring time consuming crimping of individual
header terminals to wires. The A4 and A5 headers on the
EME190 are used to connect the logic and data signals to the
other hardware for logic control and the LCD display.
MICROCONTROLLER: The PIC 18F4520 Microcontroller is
pre programmed with a boot loader to protect the software
copyright. The boot loader allows for firmware updates to be
programmed through the A6 serial port using a USB to serial
adaptor and Microchips quick programmer software ( AN851 )
available from the Mini-Kits website. The same cable that
allows remote operation via a computer using Ham Radio
Deluxe can be used. A standard PIC programmer cannot
be used on the ICD programming port as it will fully erase
the boot loader in the chip. All information regarding up-
dates of the firmware software can be found on the M1 DDS
Controller webpage.
USER INTERFACE: The M1 DDS uses the EME189 control
board as a wiring interface between the PIC Controller board
and a EC12E rotary encoder, 4x4 Numeric keypad, and 16x2
LCD display module. The rotary encoder and 4x4 keypad
allow the user to input changes to the functions, and the LCD
