Hello guys,
I am looking for PIC implementation for voltage to frequency converter (VFC).
Program must generate square wave signal with equal time ON/OFF based on the value from analog input.
10V = about 50KHz
0V = OFF
10mV= 50Hz (lovest resolution of the input)
Linearity and repeatability is important, max frequency can be 30KHz and higher.
Response time can be up to 0.5 sec, lower is better.
I have available PICs to try: 12F675, 16F628, 16F670, but can obtain any other, if necesary.
Actually my task is a little more complicated, but if I find this, I'll ask the rest.
Thanks
