# VF60 WiFi Driver
|
||
|
|
|
||
|
|
Minimalistic WiFi driver software for VF60.
|
||
|
|
|
||
|
|
## Connection
|
||
|
|
|
||
|
|
Use the RS-232 port, as documented [here](https://github.com/ggajoch/vf60-vfd-display).
|
||
|
|
Note that the connector on the display is RS232 voltage levels - to connect an ESP8266
|
||
|
|
you have two options:
|
||
|
|
|
||
|
|
1. Use a level shifter like MAX3232.
|
||
|
|
2. Disassemble the display and remove the internal level shifter,
|
||
|
|
then connect the ESP8266 directly to the level shifter pads
|
||
|
|
on the PCB.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
Change the SSID and password at the beginning of the file. Flash using Arduino IDE.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
* `http://<display IP>/display?line1=...&line2=...` - sets display content
|
||
|
|
* `http://<display IP>/brightness?brightness=0..5` - sets display brightness
|
||
|
|
|
||
|
|
## Language support
|
||
|
|
|
||
|
|
On the HTTP side, use UTF-8.
|
||
|
|
|
||
|
|
On the display side, the text is converted to CP-852 (Polish codepage)
|
||
|
|
as that's the author's native language. To add support for more languages:
|
||
|
|
|
||
|
|
1. Add and use a function like `UTF8toCP852()` but supporting a different codepage.
|
||
|
|
2. Add and use a function line `codepage_852()` but switching the display to a different codepage.
|
||
|
|
To find the correct invocation, use trial and error, trying different values instead of `\x07`.
|
||
|
|
|
||
|
|
Pull requests are welcome to add more language support; I won't do it because I'm lazy.
|
||
|
|
|
||
|
|
## TODO
|
||
|
|
|
||
|
|
- Show the display's IP address upon startup.
|
||
|
|
- Add more languages.
