It shows an I2C communication between a PIC 16F877 and a DS1337. The microcontroller ask for the second and the RTC gives it on BCD format. See the code at pic16f877.dmchihuahua.com/comunicacion_i2c.htm

  • Well you can use MAX232 if you want to spend, but also you can interface it with transistors...

  • @trovicho Hi. To interface a PIC with the PC you must use the MAX232 IC

  • Vaya mierda de video...

  • hey man. I wanna know something. I wanna interface a PIC18F with the PC via I2C. How do you know what is reading into the PC???

  • for PIC16F877A...which pin for the output?..are you use CCP1?

  • Hi, I've posted an oscilloscope trace of the i2c SDA signal for almost the same situation (mine's a 16F877A talking to a DS1307)
