I've recently encountered an issue with my GC9A01 or my Arduino UNO display.
Initially, the display was powering on and booting up properly, allowing me to utilize touch capacitive control in a demo mode. However, it has now started to exhibit a dull flashing behavior instead.
I've attempted some troubleshooting steps, such as testing the display powered by a power bank bank instead of mac book and trying the same GPIO configuration on another device (UNO R4), which didn't yield the expected results. The R4 didn't even light up the display to a full flash, whereas on the Uno, it was interactive straight away upon power up out the box.
I've double-checked my wiring and configuration, and everything seems to be correct. At this point, I'm not sure whether the issue lies with the display itself or with the Uno or whether its a hardwar or software issue,. I've considered a few options:
To me, it seems like more of a soft issue rather than a power issue. The "dull flashing" exhibits a consistent pattern and responds with a debounced nature to pressing reset. It appears to be powering up and following some type of commands, just not acting how it was previously.
If anyone has experienced a similar issue or has any suggestions on how to further troubleshoot this problem, I would greatly appreciate your insights.
