![]() The MCP9700/9700A and MCP9701/9701A family of Linear Active Thermistor™ Integrated Circuit (IC) is an analog temperature sensor that converts temperature to analog voltage. On the Mini Development Board the temperature sensor MCP9700 is connected to pin P0.28 of the controller i.e, AD0.1 via jumper J11. The maximum possible input to ADC is 3.3V which gives output reading as 1023 (The maximum value that can be represented in 10 bits), and thus the resolution is 3.3V/1023=3.22 mV. ADC0 has 6 channels & ADC1 has 8 channels. LPC2129 has two 10-bit successive approximation ADCs. ![]() The LPC2129 Development Board – Mini has on board temperature sensor MCP9700, here in this section we discuss the interfacing of the same with its host controller LPC2129. ![]() ![]() The “LPC2129 Interfacing Temperature Sensor” wiki discussed here is in reference to the rhydoLABZ make LPC2129 Development Board-Mini, however it makes no difference even if the board used is either LPC2138 Development Board-Mini or LPC2148 Development Board-Mini.i.e, this interfacing guide is common for LPC2129/LPC2138/LPC2148 Mini Development Boards from rhydoLABZ. ![]()
