BROSE9323 driver
An Adafruit_GFX driver for Brose flipdot panels, shared by both firmware targets.
The constructor is BROSE9323(width, height, panel_width, flip_time_us = 280). This
project uses BROSE9323 display(84, 19, 28).
Build modes
| Flag | Used by | Behaviour |
|---|---|---|
| (none) | Nano | Drives the panel through GPIO. Keeps an old and a new frame buffer and flips only the dots that changed. |
-D ESPSERIAL |
ESP32 | Holds no buffer. drawPixel, fillScreen, display and setTiming are sent as serial commands to the Stream passed to begin(&Serial). |
-D FLIPDOT_PLCC_ADAPTER |
Nano (optional) | Uses the pin mapping of the PLCC adapter board. |
The flags are set per environment in platformio.ini through build_flags. Don't
#define them in the header.
Notes
- In direct mode (
setDirect(true)) every pixel is flipped right away, without a call todisplay(). print()maps German umlauts (ÄäÖöÜüß) to the code page 437 glyphs used by the GFX font.- On an ATmega168 the old buffer is left out to save RAM. Every
display()call then flips all dots.
