Rickey, you published I2C code in 8052 forum.

Which line in your send and receive routine for acknowledge ?.

I read in a routine published by Rentron Electronics for AT89C2051 + DS1307, for example in their send_byte routine, it used JNB SDA to check for acknowledge.

What is the function of rlc c in your routine ?.


Thanks,
SGH

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
