Serial I/O and Three Wheels Driver

[weiqiang]

been busy for weeks...just gave it a try, it didn't seem to work...gonna look into it tomorrow...here is my code

#include <serial_IO.h>

int main()
{
   // inituart(250); // need a bit analysis
   // 256 - (22101500/384/9.6k) = value that needs to be passed up
   // since CPCON = 0x80, the PCON.7 is enabled, so the calculation should be
   // 256 - (22101500/192/9.6k) = 244, which 0xf4
   inituart(0xf4);
   
   while(1)
   {
   char c;
   c = getchar();
//   c = c + 1;
   putchar(c);
   }
}

okay, it works now with  inituart(0xe8), I think the reason is that PCON|= 0x80, 1000 0000, so SMOD.1 is set, SMOD.1 is not the doubler while the SMOD.0 is....so i am supposed to use the calculation that contains 384...

Hi Doug
    Is "using 1" mean using register bank 1 ? Is it right ?

hi mviboolr

using 1, 1 = mode 1
