Hi,
I need to design a controller for a machine with these needs:
- 3 temperature measurements (3 x A/Ds).
- a heater / cooler control that is duty cycle controlled over a period of perhaps minutes (a PWM with a period of minutes).
- a timer (count up or count down) showing time accurate to the second.
- an RPM circuit for up to around 40 RPM and down to 5 RPM.
- access to an EEPROM.
I'm planning on using a PIC16F877A. I was also planning to use a 40 x 4 LCD display.
Is this all possible on the one PIC ?
I'd appreciate some discussion because I'm losing my mind with this one!
Cheers,
