Overview
The TS-RELAY8 is PC/104 compatible peripheral board that provides eight independent software controlled PC board relays. This daughter board is compatible with any PC/104 main board.
Getting Started
Get the PC104 base address for 8bit access from your SBC page. You will use this as the base and add the other addresses for the registers. For example, on the TS-7800 this is 0xEE00_0000. If you have no jumpers set on the TS-Relay8, then the base address of this board will be 0xEE00_0140.
# This is only needed on the TS-7800
pc104on # part of ts7800.subr in fastboot
# Read the Identifier. This will return 0x9b
peekpoke 8 0xEE000140
# Turn off all of the relays
peekpoke 8 0xEE000142 0x00
# Turn on all of the relays
peekpoke 8 0xEE000142 0xFF
TS-Relay8 Programming
The simplest method will be to use system/popen calls in C/C++.
