#155497 - Actually that was a good place to start but... Responding to: ???'s previous message |
They are 3 hours behind me and won't be open til much later. I did find their master and slave examples and found out that the header file for the LPC924 does not have the needed data in it to set the bits for the I2CON control register.
So the code generator is using the correct generation, but the default header file for Keil is incomplete. I fixed it by following the model and reapplying it to my 924 and blamo.....back in business. So I guess a thank is in order......thanks! For everyone else, add this to your header file for I2C protocol and it will fix the problem in C with Keil /* I2CON */ sbit NC1 = I2CON^7; //RESERVED sbit I2EN = I2CON^6; //I2C enable sbit STA = I2CON^5; //Start Bit sbit STO = I2CON^4; //Stop Bit sbit SI = I2CON^3; //Interrupt flag sbit AA = I2CON^2; //Assert Acknowledge Flag sbit NC2 = I2CON^1; //RESERVED sbit CRSEL = I2CON^0; //SCL clock select |
