Hello everyone, I'm new to this forum.
My project is due in 1 week and I can't figure out why my code doesn't work. I'm doing an analog to digital conversion from the port AN0 and I must send it via the USART. The rate of transfer must be 19200. When I program it in the microcontroller it doesn't send anything through the serial port. PLS HELP !!! Thank you 

Initialisation
movlw B'11101111'; RC6 and 7 must be set to 1(it's in the datasheet)
movwf TRISC

movlw 0x02; 0x02 =19200 bps (calculated for 4mhz clock, it’s in the datasheet)
movwf SPBRG ; register for setting the transfer rate

movlw B'00100100' ;
movwf TXSTA; activate asynch transmition
movlw B'10000000'
movwf RCSTA ; activate serial port for receiving (i dont know if this is necessary


movlw B'00000001'
movwf ADCON0 ; AN0 selected, idle state, A/D enabled

movlw B'00000000' ; VDD and VSS set as references
movwf ADCON1 ;

movlw B'00001000' ; small endian(only interested in ADRESH), aquisition time 2AD, aquisition clock FOSC/2 (This might be the problem)
movwf ADCON2

Main
call conversion
goto Main

conversion
bsf ADCON0,GO; starts the conversoin
Wait
btfsc ADCON0,GO; waits for the conversion to end
goto Wait

movf ADRESH,W ; moves the 8 most significant bits in W
movwf TXREG ; W to TXREG, serial transmition register

Transmisiune
btfss TXSTA,TRMT; it TRMT is 1 the transmision is done
goto Transmisiune
return

end
