Tech-Note: Add Real Time Clock to the TRS-80 Color Computer
CoCo 1/2/3. This tech-note also includes a circuit
to control the X10 CM17A (Firecracker) transmitter.

Sheets 1 thru 6 show schematics for alternate interface
circuitry to the DS1302 Real Time Clock. A section of the
circuitry implements control of the CM17A transmitter.

Addresses FD00-FDFF are used for these functions.

A. Principle of operation for the DS1302. Address lines A2-A5
are used for the DS1302 several interface lines.

1. A3 is used for the CE (chip enable) pin. Assembly code
TST FD08 will set CE to high level. TST FD00 will set CE
to a low level.

2. A2 controls the CLK (clock) pin. Code TST FD04 will set
CLK high and TST FD00 will set it low.

3. To enable data bits to the I/O (input/output) pin A4 is used.
Code TST FD10 enables the data path to the DS1302. Code
TST FD00 will disable the path.

4. To send data bits (0/1) to the DS1302 (commands and
data), A5 is used in conjunction with A4 of item 3 and A3 of
item 2. To send a bit=1 (A5), CE line must be high, I/O line
must be high then CLK line must go high.
A code sequence like:
TST FD08
TST FD38 or FD28 for bit=0
TST FD3C or FD2C for bit=0
will send a data bit (A5)to the DS1302.

5. To read data bits from the DS1302, after a command is sent
requesting the value of hour, minute, second, etc. The data
path to the DS1302 must be disabled during reading. A data
bit is clocked from the DS1302 by setting the CLK pin low.
A code sequence like:
TST FD08
LDA FD08
TST FD0C
will transfer a data bit from the DS1302.

6. Data is sent and received (to/from) the DS1302 low order
bit (LSB) first.

REV. 1/2013

B. Principle of operation for the X10 CM17A. Address lines
A0 & A1 are used for the CM17A two interface lines. Note,
the IC 1488 interface to the CM17a requires +/-12V. Wires
must be added internally to bring these voltages to the
cartridge 40 pin connector (pins 1 & 2).

7. When the CM17A is in standby both interface line must be at
low level. Code TST FD00 will set both lines at zero.

8. To cause the CM17A to transmit a bit=0, A1 is high while A0
is low. Code TST FD02 will set bit=0 state. Likewise to
transmit bit=1, code TST FD01 which sets A1 low and A0 high.

9. The CM17A requires the bit state held for 0.25 milliseconds
followed by standby state held for 0.25 milliseconds, this
results a 0.5 millisecond pulse for each bit transmitted.

10. The code sequence to transmit a bit=0:
TST FD02
CALL HLFDLY .25 ms delay
TST FD00
CALL HLFDLY .25 ms delay

11. The code sequence to transmit a bit=1:
TST FD01
CALL HLFDLY .25 ms delay
TST FD00
CALL HLFDLY .25 ms delay

12. A X10 control command consists of 40 bits, a 16 bit header
a 16 bit command/unit and a 8 bit trailer.

C. Circuit components are available which include the IC's and
DS1302 with the crystal (32.768Kz). Misc parts such as
wires, sockets, resistor, capacitors, etc are not included.

D. Software is available which includes functions for both the
Real Time Clock and the CM17A X10 transmitter. Includes
both executable code and source code on cassette tape. A
hard copy of the Machine Language (ML) code is included.

E. Contact the author by e-mailing john.e.hieber at juno.com
for availability and prices.

F. Sheet 5 & 6 shows the schematic using programmable peripheral
interface adapter IC's. The Z80 PIO and the MC6821.
