Hi All!
I want to get serial data byte-wise into MCU.
Is it correct to do as following:
#include <io430x14x.h>
#include <in430.h>
/*========Defines section===================================================*/
#define IN_PIN P1IN_bit.P1IN_1
/*========== Variables section================================================*/
unsigned char bit_num; //number of bits - 8
unsigned char buffer; //buffer for serial data
volatile struct
{
unsigned char ser_bit: 1;
}
mybits;
void Get_byte(void)
{
for ( bit_num = 7; bit_num==0; -- bit_num)
__delay_cycles(256); //32us – bit duration is 64us – I get it in the middle
mybits.ser_bit = IN_PIN;
buffer |= mybits.ser_bit >>bit_num;
}
void main(void)
{
cpu_init();
while(1)
{
if (IN_PIN==1) //start of receiving
Get_byte();
}
}
