I am using the uPSD3254BV-24U6. I am able to get UART1 working fine. And trying to setup UART2 to work like the UART1. When I make the changes to the SCON2 in the UPSD.h file and try to complie it using Keil, I got the following errors messages:
E:\COMMUN\KEILV70\C51\INC\ST\UPSD.H(264): error C146: 'SCON2': invalid base address
Here is what I have in the UPSD.h file:
// --- UART2 SFRS ----
sfr SCON2 = 0x9A; // UART2 Serial Control
sfr SBUF2 = 0x9B; // UART2 Serial Buffer
:
:
/* SCON 2 */
sbit SM02 = SCON2^7;
sbit SM12 = SCON2^6;
sbit SM22 = SCON2^5;
sbit REN2 = SCON2^4;
sbit TB82 = SCON2^3;
sbit RB82 = SCON2^2;
sbit TI2 = SCON2^1;
sbit RI2 = SCON2^0;
Any idea what I did wrong? From looking at the datasheet, the Sfr address is correct.
Best Regards.
