UART2 RX TX initialization-how to use?
Hello, I have problem with initialization UART2 in my project(STM8S105). Below you can see part of my code, what am i doing wrong?
I'm trying to send sign to LCD display.

[code]
void UART2_Cmd(FunctionalState ENABLE);

void UART2_InitGPS()
{
    UART2_DeInit();
    UART2_Init( (u32)9600, UART2_WORDLENGTH_8D, UART2_STOPBITS_1, UART2_PARITY_NO, UART2_SYNCMODE_CLOCK_DISABLE, UART2_MODE_TXRX_ENABLE);   
}

void UART2_SendData8(u8 Data);

u8 UART2_ReceiveData8(void);


void main(void)
{
    char tmp;
    LCD5110_init(); //function which initialize LCD
    LCD5110_set_XY(0,0); //function which set rows and columns in LCD
    UART2_SendData8(36);
    UART2_ReceiveData8();
    tmp = UART2_ReceiveData8();
    LCD5110_write_char(tmp); //function which send characters to LCD
}

[/code]
I have to mention that i have no errors after compiling code and if I use function like this everything works fine(but I need UART to racive data from GPS and send it to LCD) :
[code]
void main(void)
{
    char tmp=33; //33 -> "!" sign in my matrix(table or haw to name it)
    LCD5110_init(); //function which initialize LCD
    LCD5110_set_XY(0,0); //function which set rows and columns in LCD
  
    LCD5110_write_char(tmp); //function which send characters to LCD
}

[/code]
BR,
Konrad


P.S. If somebody wants to see whole code let me know :)
