AT89S51 + AT24C01A

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
