Hyper Terminal Displaying Random Characters [PIC to PC via UART]

[Dave]

arson88 , If you want to see the characters received by the PC you should be running a terminal emulator program that will allow you to see the hex value of the received byte. I always use an old program called QMODEM which allows you to see any non printable characters like control characters. You do realize that there are more than 127 non printable characters that are possible to be sent via RS-232. I do not use Hyperterminal as the screen view is not big enough. There are a lot of other programs out there that will allow you to view the received byte value... Just look...

BTw, i am using http://www.cytron.com.my/viewProduct...7nn82zcVu7Ut0=
, a USB to UART Converter.

nvm, i got the program right..
INCLUDE “modedefs.bas” ‘ Serial communication mode definition file
DEFINE OSC 20 ‘ Oscillator speed is set to 20MHz
TRISB = %11111111
TRISC = %10000000 ‘ RC.7 => USART RX pin set to input
PortC = 0
SPBRG = 129 ‘ Baud Rate = 9600
‘ Variable definition
‘ ===================
‘
count01 VAR BYTE ‘ variable to store TXREG content
TXSTA = %00100100 ‘ Enable transmit and asynchronous mode
RCSTA = %10010000 ‘ Enable serial port and continuous receive
mainloop:
IF (PortB.7 = 1) THEN
FOR count01 = 1 TO 30
PAUSE 2000
TXREG = count01 + $30 ‘ Transmit Data
HIGH PortD.2
PAUSE 2000
LOW PortD.2
Next
ENDIF
GOTO mainloop
END

The result displayed in Hyperterminal:
ASCII Character: 1, 2, 3, 4, 5, 6, 7, 8, 9, :, ; < until the 30th ASCII Character

How do i convert the ASCII characters i received via Visal Basic 2010's serial port into integers?

I used tiktakx's vb coding http://tiktakx.wordpress.com/2010/11...10/#comment-97
