用STC89C58单片机做的数据采集和控制，12位AD转换使用TLC2543，通讯协议采用MODBUS（RTU），通过拨码开关改变从机地址，支持模拟量或数字量的读写。（4路模拟量输入、6路开关量输出（继电器输出）、8路开关量输入）开发环境:KEIK 7.06 (2006-7-5，C-C++,61KB,17次)

-Microcontroller to do with STC89C58 data acquisition and control, use 12-bit AD converter TLC2543, communication protocol using MODBUS (RTU), by DIP switch to change the address from the machine to support analog or digital literacy. (4 analog inputs, 6-channel digital output (relay output), 8 switch input) development environment: KEIK 7.06 (2006-7-5, C-C++, 61KB, 17 times)
