Its been a while since my last posting to this is whats news
- There are around 25 tick tock timers "in the wild" running various school/factory bell systems
- Issues with quality control on ili9325 screens (white flashing)
- Product manual in the works
I have been having quality issues with ili9325 screens, with around 15% of produced boards having screen which flash white when touch is being read from the screen.
Due to this I have long terms goals to switch over to the more common ili9341 screens
This screen will also allow PWM screen dimming which is something I (regrettably) didn't pursue the current ili9325 production version.
After failing to get it working the ili9341 to work with my Mega2560 I realized the screen isnt 5v logic tolerant (despite what the ebay listing claimed....)
Since I didnt have the components to to a logic conversion I decided to attempt a port of the firmware over to the ESP8266 NodeMCU
After breaking most of the timing features by updating the RTC library, switching to an ili9341 library and XPT2046 touch library, a few glasses a wine and about 5 hours I have breadboard ported the TICK TOCK TIMER to the ESP8266 / ili9341!
Still work to do
- Port all clock code firmware over to updated library
- Add EEPROM.commits to all EEPROM write (currently not saving on power off!)
- Add NTP (Why not?)
- Add NTP settings such as time zone
