Reading Multiple Keys presses over I2C using a LK204-25

[Dime]

It appears that when there are multiple key presses cached and I poll for a key press using I2C the LOW bit is set instead of the HIGH bit. I have tried this using the UProject software and RS232 and it works as expected there (the HIGH bit is set). However when using I2C the LOW bit is set. I have PCB revision 2.0 and firmware version 5.6.

Hello Dime,

Thanks for your post.

This was a known issue and has now been fixed in an updated firmware. Please see this PCN.

PCNs can be found here.

Thanks,

Can you please explain the procedure for updating the firmware in my LK204-25 device? Do I need to send the board back in or can I update it my self with a PC utility?

Hello again,

Unfortunately, we will have to get your board back here for reprogramming. I will get RMA dept to contact you for details on how to do this.

Thanks,
