mladenNixie Tap will have 4 "slots" for information display. For the time being, these slots are planned:
- Time
- Date
- Bitcoin value
- Ethereum value
The user knows which slot is currently displayed by observing the blinking dot position.
You'll notice that 50% of slots are taken by cryptocurrency. Hopefully, 4 digits won't be enough to display the price :)
State diagram looks like this:
Basically, it should
be an interrupt driven program. So, let's dive in:| Prototype features | Final features | |
| init | Connect to WiFI using hardcoded credentials, get NTP time and store onto RTC | Serve a WiFi Manager-like hotspot, for user entry of WiFi credentials |
| main | Wait for RTC interrupt and poll analog input to detect taps | TBD |
| RTC interrupt | RTC fires an interrupt every 1s, this signals the main function to refresh display | |
| Display time | Read time from RTC and refresh display | |
| Display date | Read time from RTC and refresh display | |
| Display bitcoin | Not implemented | Read BTC value from Internet and display value |
| Display ethereum | Not implemented | Read ETH value from Internet and display value |
