PIC based “intelligent” A/D converter
The PICADC is a simple 12-bit, 8-channel analog to digital converter (with 4 additional digital inputs), which may be connected to the PC through the serial interface (RS232).
The sequence of sampled channels, and sampling frequence are programmed by the PC.
The maximal sampling frequency is limited by the data transmission rate, and at 115200 baud is equal to ca. 3kHz for 1 channel without digital inputs, and to ca. 500 Hz for 8 channel with digital inputs.The analog input voltage range is -2.5V to 2.5V.The digital inputs may be used for recording additional digital signals, eg. the time code used to synchronize the recorded data with other events.The PICADC is based on PIC16F84 (or PIC16C84) microcontroller, and MAX190 (or MAX191) ADC.
