I need explanations to understand the meaning of this. PIC16f877 has a register SSPCON and the four LSB are the configuration I2C. If are '1000' means i2c master mode but if are '1011' are i2c firmware controlled master mode. What is the diference btw them? In the tru

I have a weird issue. I've used the hardware I2C on the PIC 16F77 with no problems between multiple chips using 2.7K to 4.7K pull up resistors very successfully. However when using the 16F877A I'm finding that I2C isn't reliable at all unless I use 22K to 47K pull ups. Weird huh?

I am building a optical tachometer for a gas turbine. I would like to try my hand at PIC programing. I have programed AVRs in the past and feel its time to try microchip's line (mainly because I got some samples from them ;-) I already designed my board layout and intend to use a
