add two IKE text display functions #99

Closed Altblechkutscher closed 2 years ago

Altblechkutscher commented 2 years ago

There are 2 ecus which also support writing on the text display of the IKE: RAD and CCM (aka the LCM).

The message of the LCM/CCM must be deleted manually (that is what happens originally when releasing the check control button at the IKE). The message of the RAD can (contrary to all available documentation) also display 20 chars. Both functions fill up shorter messages with trailing 0x20 spaces.

The existing IKE function always displayed a trailing "3" for me.

I personally use these functions to display a welcome message on ignition change. grafik

Here we have to discuss how this can be saved in the EEPROM + editable for the end user, might be content of further commits.

Hello @Altblechkutscher!

Good on you for getting stuck into some code 😄 . You're on the right track here, but there's a few traps with the cluster messaging.

I'd recommend joining the BlueBus slack if you're interested in making ongoing contributions. It would allow you to sense check any ideas and ensure that you're making the best use of your time. There's a few tragic BMW enthusiasts there, so you'll be among friends 👬 .

Yeah sure, just let me know. First baby steps again with µC from my side, got stuck in AT90 in the past :)
