# Nixie-clock
This arduino project is a custom firmware for the [EleksTube IPS Nixie Tube Digital Clock](https://elekstube.com/products/elekstube-ips-rgb-digital-clock-imitate-nixie-tubes-clock-6-digit-lcd-proposal-mode-custom-style-best-boyfriend-gift-shelf-clock).
This repository take some code from the [frankcohen/EleksTubeIPSHack](https://github.com/frankcohen/EleksTubeIPSHack) repository.
This project provide a simple base splitting the different components of the clock:
- Back Lights
- Bluetooth (BLE)
- Wifi
- Buttons
- Screens
- Time
- Files (LITTLEFS)
Each componenent can call the others using the Clock instance.
# Bluetooth (BLE)
The current implementation provides some simple example of the bluetooth implementation. (Not used in the original clock.)
A class can extends the **BluetoothService** class, it abstract the interaction with the BLEManager class.
Here is a simple example to turn on/off the back lights with python
(start python using `python -m asyncio` to use await)
```python
from bleak import BleakScanner
from bleak import BleakClient
# Get the device
device = [device for device in await BleakScanner.discover() if device.name == "Clock Service"]
assert len(device) == 1
# Create BleakClient
client = BleakClient(device[0].address)
# Connect
assert await client.connect()
# Send 0 value to address POWER_UUID
await client.write_gatt_char("bb5e995d-5863-4aa1-bafe-0e6a9fd4aa71", b'\x00', response=True)
```
## Upload a new images
First you need a bmp image in 135x240.
```python
# Init the upload for the number 0
await client.write_gatt_char("c2285d2f-44c5-4abb-af86-9d159f351081", "/0.bmp".encode(), response=True)
with open(f"data/0.bmp", 'rb') as f:
bytes = f.read(512)
while bytes:
await client.write_gatt_char("c2285d2f-44c5-4abb-af86-9d159f351082",
len(bytes).to_bytes(2, byteorder='big') + bytes, response=True)
bytes = f.read(512)
await client.write_gatt_char("c2285d2f-44c5-4abb-af86-9d159f351083", b'close', response=True)
```
## Set wifi credentials
```python
await client.write_gatt_char("c1eac326-9ded-4148-90c1-6289cdbf5103", "ssid;password".encode(), response=True)
```
## Set TimeZoneOffset
Paris is +2 Therefore we add 2 hours to the default time:
```python
await client.write_gatt_char("b13c119b-2a41-4c37-8f5e-f9c914566d51", (60*60*2).to_bytes(4, byteorder='big'), response=True)
```
## Events
The clock can have up to 5 events. An event has a few attribute
```C++
struct Event {
uint8_t day;
uint8_t month;
uint16_t year;
char message[24];
};
```
The year field is optional, to have a repeating event over the year, you can set the year value to UINT16_MAX (65535).
To set an event you can use the following command
```python
await client.write_gatt_char(
"fd82dda7-cc8e-43d2-aa81-48277a63e551",
(4).to_bytes(1, byteorder='big')+ # The index (0 to 4)
(2).to_bytes(1, byteorder='big')+ # The day (1 to 31)
(7).to_bytes(1, byteorder='big')+ # The month (1 to 12)
(65535).to_bytes(3, byteorder='big') + # The year (65532 to ignore it)
"Hello\nWorld".encode(), # The message to display: MUST BE 24 characters or bellow.
response=True
)
```
