Super Simple WS2812 Lib for STM32F1xx microcontroller

PWM + DMA based driver for WS2812 LEDs

• Top level API in wsLED.h
• Designed for STM32F1xx microcontroller with the appropiate Std.Periph Lib.
• Output port can be adjusted via wsConfig.h
• NO IRQs are used in this driver, the DMA uses the cicular mode and the synch gap is included in the led bit buffer
• The led count can be adjusted in wsConfig.h or detected automatically

    LED.Red = i;
    LED.Green = i;
    LED.Blue = i;
    wsLED_SetAllLed(&LED);
    wsLED_UpdateStripe();  /* Move data into DMA buffer */
    DELAY_SOME_MS();
    i++;
  }
  /* Here be dragons */
