- New example sketch for Home Assistant users, thank you netmindz
- Updated a failure of the intepretation of "9" in
Balboa_GS_Interface.cpp - Changed to ElegantOTA in
Balboa_GS_MQTT.ino - Added
StopandResetMQTT interface inBalboa_GS_MQTT.ino
- New function
updateTemperatureadded to set a temperature value instead of "push" button x number of times - Balboa_GS_MQTT sketch updated with AsyncElegantOTA
- Basic functionality to read and set status using a Balboa_GS developed library. Two examples are provided, first with simple read and set functionality and the second using MQTT for remote access.
| PIN | Description |
|---|---|
| PIN 1 | Functionality unclear! |
| PIN 2 | Functionality unclear! |
| PIN 3 | Button data |
| PIN 4 | GND |
| PIN 5 | Display data |
| PIN 6 | Clock |
| PIN 7 | 5 VDC |
| PIN 8 | Floating output |
PWM output from control system, same on both pins. Unclear functionality for these PINs still! Maybe some internal light supply?
50Hz, pk-pk=18v, mean 5V
- The clock is pulsing 7 times for each chunck of display data, totaly 39 bits and 3 times for button data. A complete cycle 42 pulses.
- Totaly of 6 display data chunks in each cycle
- Each cycle is repeted every 20 ms
- One total cycle duration 1.88 ms
- Bit duration for display data is 10 microseconds for display data
- Bit duration for button data is 60 microseconds
Display shows 37.5C - How does that translates into the bitstream? The first 4 chunks is coded in BCD to 7 segment LCD (see reference) but only with 7 bits sinse the LSB always is (0).
3 = 1111001(0) = 0x79 (Chunk 1)
7 = 1110000(0) = 0x70 (Chunk 2)
5 = 1011011(0) = 0x5B (Chunk 3)
C = 1001110(0) = 0x4E (Chunk 4)
| Chunk 1 - bit(0-6) | Chunk 2 - bit(7-13) | Chunk 3 - bit(14-20) | Chunk 4 - bit(21-27) | Chunk 5 - bit(28-34) | Chunk 6 - bit(35-38) |

Since the display and controler unit hardware design is unknown an OR-gate is used to prevent damage if simultaneous HIGH/LOW levels from display and Arduino.
