Eval¶

Slider would not have adequate resolution.
Usecase is only on/off. Single Button could do the job.
Fancy ring would be nice.
90°-LEDs zeigen alle nach 'innen'.

MCU¶

• STM32L552CCT6 way too big
• STM32F042 has a touch sensor controller according to datasheet, copilot says "no".

To be verified¶

• Use Miniminutnik Acryl plates to check if text is readable/illuminated
  • Looks very nicely
• Prepare STM32F42x eval board
  • On touch area directly, another via JST
  • CANBus
  • Debug
