Code Translation from cc5x to ccs

[Jean_Paul_Talledo]

Hi everyone I want to translate the following code from cc5x compiler to ccs compiler. My first problem are the port declaration for a specific bit of the port like PORTA.x.Then I want to translate how to access one bit of specific variable like temp.x and I hope someone can help me to convert this code. Thanks very much.

if you edit your post and include [.code] (leave out the .) before the start of the code and [./code] (leave out the .) after the end of the code it will make it a lot easier for people to read.

change the format from: #define TX_CE PORTB.0

to: #define TX_CE PIN_B0


add #define uns8 int


change the format from: 0b.0000.1100 to 0b00001100

my problem translating is how to convert the temp.0 to ccs function or variable.


code:



for(j = 0 ; j < 8 ; j++) //8 bits each
{
temp <<= 1;
temp.0 = RX_DATA;

RX_CLK1 = 1;
RX_CLK1 = 0;

}
