Microcontroller › 8051 › pullup resistor value for I2C › hi jenifer… u have to check
February 7, 2014 at 6:32 am #10954
u have to check following things..
1> declaration of variables that u have declared for I2C operations
becuase if u r doing operations like shifting then there will be problem in declaration type of variable i.e int, char, unsigned int etc. etc
2> for 5 volt application i think 4.7k pull resistor is ok.
