16f876 28 pin connecting x10

Post by ukweb »

Hi
The previous post response was as follows:
( I would suggest you used the screw terminal blocks available for ports A and B to connect to the X10 transceiver, or use the terminal block headers to connect to ports C / D (if you are using a 28 / 40-pin chip). )

So by using a 28 pin (16f876) -- matrix multimedia board v2 to connect to the x10 transceiver (xm10u) .
Where are the terminal block headers, i cant spot them on the board v2, are the terminal block headers mentioned on the data sheet. Please let me know.
thanks

The screw terminals on the v2 board are located at either side of the board, just above the sensor sockets - portA to the left and portB to the right.

If you are using an '876 I would suggest using portC via the 40-way expansion header. This header is next to the DIL socket for 40-pin PICmicros. It's pin-out replicates the 40-pin chip, so look at the datasheet for an '877 (or similar) to find where portC is located.

Note that on some boards, we did not actually fit this 40-way header, but the holes will be there and you should be able to solder directly to them.
