I'm using an LK162-12GW on an I2C bus behind an IPMI BMC on an Intel server board. Therefore my problems might be in my use of the OpenIPMI library I'm using on Linux to get at the I2C bus. But let's ignore that for the moment...
With each write to the display, the first character displayed is a pair of parallel vertical bars that run full character height in pixel colums 2 and 4 (numbering colums 1-5). This character is not in the built-in character font, so how is it being displayed? All chars after that (in the same write) are displayed properly. In fact, if I write ascii char 8 (BS) first, then the rest of my string, it is all displayed correctly.
Can anyone tell me what's going wrong? What does this char mean?
Thanks,
Dave
