Question and issues:
1. ADP1048 Programming: EEPROM programing and Unlocking issues
2. GUI screen resolution and size work-around
Issue: 1
issues, programing and unlocking command not working to unlock the EEPROM of the ADP1048. After powering on the device and querying the FE81 register, the expected value is not being returned.
Cause:
There is a data sheet error regarding the unlock command password. The customer initially attempted to unlock the EEPROM using the command D5 FF twice, which did not yield the expected results.
Resolution 1: unlocking password is 00
Instead of sending the command D5 FF FF, It need to sending the individual command D5 00 twice. e.g. D5 00; D5 00 and the password is "00" not "FF".
After sending these commands, check the FE81 register again. The expected return value should indicate that the EEPROM is unlocked, specifically looking for the EEPROM_UNLOCKED bit to be set.
Issues 2
The GUI screen size might be out of proportion from the GUI.
Resolution 2:
A user successfully normalized the display by changing the scaling settings before calling up the GUI, resolving previous display issues encountered with the software.
There will be sw updates for the ADP1047/48 GUI due to be release end of the year 2024, which will address existing issues and add enhancements.
for the interim, 1920x1080 resolution is OK but set the scaling to 100%.
It will make texts quite small for14” laptop displays but should be OK for 16” laptop or an external display like 24”.
