Hi all PICMasters! I've just decided to make my old PICADC project (I started it in 1996, if I remember, and then put it on hold to finish my PhD thesis) available for all interested in using PC for analog data acquisition. Tech specs: * Eight 12-bit analog inputs * Input voltage +- 2.5V * 4 digital inputs (eg. may be used for recording of "time code" to synchronize the recorded data with other events) * Selectable data transmission baud rate (115200, 57600, 38400) * Sampling rate programmable from the PC (maximum: ca. 3kHz for one analog input without digital inputs, and ca. 500 Hz for 8 analog inputs with digital inputs) * The sampled channels sequence programmable from PC (up to 8 channels) * The source of simple demonstration software for Linux available Everything freely available and royalties free. Take a look at http://www.ise.pw.edu.pl/~wzab/picadc/picadc.html to get more information. Any comments, improvements, suggestions are appreciated. I hope that it can be useful for the PIC community. -- Wojciech M.
