aduc7026.h header file doubts

Dear Sir,

 

I am using full version CrossStudio for ARM Release-1.7, Build 20 for ADuC7026 Evaluation Board of Analog Devices. I could compile and run a few programs such as ADC, UART, PWM, Timer, etc without any problem. But when I tried I2C program, it is not going through. I have noticed a few points in the aduc7026.h header file which I have mentioned below

 

1)      Registers such as I2C0CFG & I2C1CFG are defined as

#define I2C0CFG (*(volatile unsigned char *)0xFFFF082C)

#define I2C1CFG (*(volatile unsigned char *)0xFFFF092C)

But these registers are of 32bits. I could not assign any value to the higher bits(such as bit11) if we define these as char. Can I modify it and define as int

 

2)      In I2C0MSTA register, the bit definition for Mater_Transmit_IRQ & Master_Receice_IRQ are not according to the ADuC7026 datasheet.

 

Please let me know how I shall go about it. My work got held up & I am not able to locate the problem. Kindly help me in this regard

 

Thanking you

Amit Biradar

  Hmm, as I said on your ticket, you need to get off of evaluation bandwagon that you've been on for two years.
