Dear All,
I need help.
I am new here & I don't know whether i join the right forum or not for asking this thing.
My company bought a 2nd-hand LED Display Board with 2 lines of LED display (each 16 digits). We are going to reprogram the software by using Visual Basic 6. We have tried it several times, but it's still not work.
This is some codes that was given to me.
Serial Protocol (serial com: RS422 9600 bps, 8 data bits, 1 stop bit, no parity).
LED LINE 1:
<STX> <0xFF> <Address Byte> <0x80> <0x90> <'P'> <'1'> <16 Alphanumeric characters to be display (including commas)> <0x80> <ETX> where Address Byte is 0x81 (both Boards). STX is 0x02 and ETX is 0x03. E.g. Transmit: [0x02 0xFF 0x81 0x80 0x90 0x50 0x31 0x55 0x53 0x44 0x31 0x2C 0x30 0x30 0x30 0x2C 0x30 0x30 0x30 0x2C 0x30 0x30 0x30 0x80 0x03] to show 'USD1,000,000,000' as Price 1 on LED Board.
LED LINE 2:
<STX> <0xFF> <Address Byte> <0x80> <0x90> <'P'> <'2'> <16 Alphanumeric characters to be display (including commas)> <0x80> <ETX> where Address Byte is 0x81 (both Boards). STX is 0x02 and ETX is 0x03. E.g. Transmit: [0x02 0xFF 0x81 0x80 0x90 0x50 0x32 0x55 0x53 0x44 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x20 0x35 0x2C 0x30 0x30 0x30 0x80 0x03] to show 'USD 5,000' as Price 2 on LED Board.
Those are the codes was given to me.
We trying to use the VB component called "MSCOMM" for the coding, but it is still not work.
Does anybody understand how to write the right code by using VB6 to communicate with the LED Display Board?
Thanks before for the help.
