I am trying to measure 10-15volts to 0.01 volt accuracy. I am using the built-in 10bit ADC on the 12F675 with 1% tolerance resistor voltage divider. I find that the values fluctuate way more than expected, +/- 0.03 volts. The voltage is coming from a regulated power supply

Hello, I've a problem with my programmer! I'm using a jdm programmer and ic-prog v1.05A. I can programming 16F84 and 16F877 without any problem. I try to programming 18F458 and 12F675 but I don't programming them :( could you tell me what I am doing now? thanks for your advices sory for my english CNT TEK.

I'm trying to use the MCLR pin for I/O on this device. The data sheet claims to do so you clear the MCLRE config bit. When I do this the device behaves very oddly (output pins go to Vdd) and it almost looks like a reset that only half happened but not exactly. I'm using INTOSC (w

Hi I'm a newbie trying to program the PIC12F675 using Hi-Techs PICLite C software. I'm having trouble setting the outputs when addressing them directly. If I do the following "GPIO = 0b00000110" It will turn on two outputs But, If I

hi guys, just completed my pwm motor control program, please have look and see if there is any obvious mistakes, it was written on mplab uses special instruction mnemonics so probably only looks correct in mplab. it works ok but the frequency a bit low. gives reasonable out

Hi groups ! I have spend a whole sunday trying to understand why interrupt of change are not working for me. I have played with those on PIC16F877 and works ok there. According to DS41190A datasheet, using interrupt of change means: In the main program: - en

I'm just starting a small project using a 12F675 and would like to use Timer1 to time the PWM signal going to a remote controlled servo. The typical 1ms to 2ms pulse with 1.5ms being centred. I've done a few small projects but I've never used Timer1 befor
