Yesterday I experimented with the Serial IO code in the FAQ. I have a couple of questions though. Here is the basic program that I wrote to try to understand this stuff:
I wrote this into hb_lib.c:
void disable_pcode_serial()
/* necessary to receive characters using serial_getchar */
{
poke(0x3c, 1);
}
Then my program looked like this:
void tester()
{
disable_pcode_serial();
printf("Press the Start Button\n");
start_button();
}
I thought that the HB would disconnect from my PC, then prompt for the Start Button to be pressed. But instead it would disconnect from my PC until I pressed the Start Button. I was just wondering why exactly this is happening?
Thanks for any help,
WilL
