Works. (On Teensy only !?)
This was 3 days of brainfuug, feel free motivating me publishing such stuff. | ![]() |

See my notes and theory docs for more detail on it's inner workings
You can either...
git submodule add <repo addr> lib/VFD_MN12832L
lib_deps = mariosgit/VFD_MN12832L
Branch "greyscales" has a version with 4 greyscales. This requires more memory and twice the CPU time.
?? copy the repo into your local libraries folder ??
see examples folder.
instanciate a display
MN12832L display;
or with your own pins... (MOSI and SCK must fit one of the hardware SPI pins)
MN12832L display(
/* pinBLK = */ 4,
/* pinLAT = */ 6,
/* pinGCP = */ 3,
/* MOSI_PIN = */ 11,
/* SCK_PIN = */ 13,
/* pinPWM = */ 20);
Call begin during setup...
void setup()
{
display.begin();
display.fillScreen(0);
}
Draw something and swap buffers...
void loop()
{
display.fillScreen(0);
display.drawLine(0,0,31,31,1);
display.swapBuffers();
}
Optimize some more drawing functions..
HLine and fillRect could be faster when 6 pixel are written at once.
virtual void drawFastVLine(int16_t x, int16_t y, int16_t h, uint16_t color);
virtual void drawFastHLine(int16_t x, int16_t y, int16_t w, uint16_t color);
virtual void fillRect(int16_t x, int16_t y, int16_t w, int16_t h,
uint16_t color);
virtual void fillScreen(uint16_t color);
// Optional and probably not necessary to change
virtual void drawLine(int16_t x0, int16_t y0, int16_t x1, int16_t y1,
uint16_t color);
virtual void drawRect(int16_t x, int16_t y, int16_t w, int16_t h,
uint16_t color);
