Hi pals, I have a BLK-202A-GW-BK unit connected to a serial interface. I have written a C program with the purpose of changing the startup message, everything works well, but when Linux is booting (exactly when the kernel is loading) a strange character is written at the top left.
Any ideas how to avoid that?
I dont remember but I think when the unit had their default starup message, no strange characer appeared.

Welcome to the forums,
What you are seeing is the serial ports being initialized by the OS and sending some garbage out, and since the display is connected, the display will do as it's told and display those characters. The current version of the display there is not much you can do about this, but in 3-4 weeks we will be releasing a new version of the LK202-25 which will have a sleep until being woken up command,

With this unit and using linux, keypad can be read ok? <n
I thought I read somewhere that linux support for interpreting the keypad input from MO units is not supported yet...

The keypad itself works perfectly on a Linux box and getting a dislay to work on a Linux box is pretty easy. (also the USB displays)dconnell wrote:I thought I read somewhere that linux support for interpreting the keypad input from MO units is not supported yet...
The SDK I wrote doesn't support fully support the keypad interface yet simply because the serial port support in Mono is not completely ready. (version 1.2 of Mono will) And just for your information, I don't have anything to do with Matrix Orbital, so it's obvious they don't support my SDK for the displays.
