my RTC project using 16f876A (8MHz)& ds3231. During the simulation into proteus, i think my RTC program does not get value from I2C device ds3231 . could you pls review my programs as attached to look at the errors associated with it.
thanks for ur time.
10, 9 ,8, 7........ I2C in Protues will not work with analogue resistor primitives... You MUST use the pullup resistor... It is for digital simulation..
Most of my simulations go above 100% CPU... To drop the simulation load remove ALL analogue resistor models..
