Hi all, I need a microcontroller with a lot of A2D and USB interface. I want to read 25 RTDs with a refresh rate of about one/100mS. Maybe PIC18LF45K50? Any better choice? Maybe Atmel? How would you approach this? thx, Vasile --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
