Working project in it´s end of alpha face.
- fix set temperature interference that occurred after a couple of hours.
- fix water temperature interference.
Working project in it´s end of alpha face.
-
Possible to change temp, control pumps and lights.
-
Detect filters curculation, heater, standard mode and eco mode.
-
Defined different button for up/down with temp up/down.
-
Over The Air update now working http://unitsIPadress/update
Identifing bits are still ongoing. List of definition you will find in the Balboa_GS_Interface.h file
This is a mix of the great work by MagnusPer project with GS510SZ and Shuraxxx, GS523DZ.
Could possibly work with the GS523DZ models as well, as its the same display, I have no ability to try this.
| 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 |
##PIN 6 (Yellow - clock), PIN 3 (Red - button data), PIN 5 (Green - display data)
- The clock is pulsing 7 times for each chunck of display data, totaly 71 bits and 4 times for button data. A complete cycle 75 pulses.
- Totaly of 6 display data chunks in each cycle
- Each cycle is repeted every 10 ms
- One total cycle duration 3.54 ms
- Bit duration for display data is 23.75 microseconds for display data
- Bit duration for button data is 71.5 microseconds
Display shows 29.5C - 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).
2 = 1101101(0) = (Chunk 4)
9 = 1110011(0) = (Chunk 3)
5 = 1011011(0) = (Chunk 2)
C = 1001110(0) = (Chunk 1)
| Chunk 4 - bit(0-7) | Chunk 3 - bit(7-14) | Chunk 2 - bit(14-21) | Chunk 1 - bit(21-28) | Chunk 5 - bit(29-71) |
|---|---|---|---|---|
| LCD segment 1 | LCD segment 2 | LCD Segment 3 | LCD segment 4 | 29 - Button down/up |
| 59 - Standard mode | ||||
This uses the same PCB developed by MagnusPer work on gs510SZ
Dont forget to give space between PCB and ESP8266 for the USB cable connection
Be surent you are using a standard Patch cable and not a crossover cable, or you will destroy the panel unit.
GS510DZ J1 Port to PCB control system port
Display port to vl801D panel
