#159944 - P89V51RD2 I2C Responding to: ???'s previous message |
Same code is working in P89C51RD2 with RTC and EEPROM in the very same PCB . But when i replace it with P89V51 everything remains functional like LCD , key pad I/O pins etc except for execution of I2C routine where it gets
[I2cstart I2cwbyte &B11010000 I2cwbyte 0 I2cstart I2cwbyte &B11010001 I2crbyte S , Ack I2crbyte M , Ack I2crbyte Ho , Ack I2crbyte D , Ack I2crbyte Wm , Ack I2crbyte Month , Ack I2crbyte Yd , Nack I2cstop ] I am using BASCOM compiler . |
