Matrix user forums

Hi

is it possible to communicate with the pc to the matrix multimedia board, say for example type a character on the keyboard and it should be dispalyed on the matrix multimedia board LCD (that is when the board is running) .

If yes what could be the C Code for that program.

thanks ukweb

You will need some kind of add-on hardware to do this. For example, we produce an RS232 E-Block (connects to the COM port of a PC) and a USB232 E-Block (connects to a USB port). You will also need to write an application on the PC that communicates via RS232.

These E-Blocks are compatible with the v3 dev board, but you will need to use a 28 or 40-pin chip (the E-Blocks ports on the v3 dev board are on portC and portD only), and one with an onboard USART module - e.g. 16F877a.

If you have a v2 dev board, you can buy an E-Blocks adapter that will give you E-Blocks ports on all ports of the PICmicro.

OK Steve,

If you have an Eblocks adaptor for V2 boards, can I get the serial module software as well?

Yes - I'll provide some example C code for RS232 comms.
