Library/example for Arduino IDE and Stm32f4 series MCU. Transmit DMX512 packets to 8 outputs (easily may be expands to 16) using DMA and timer TIM1. Simple and powerfull.

Work with core by ST (https://github.com/stm32duino/Arduino_Core_STM32)
Lib almost dont use resources of MCU!
Eats about 20KB of RAM
Framerate - 41 Packets/sec.

Tested on stm32f405rgt6 and stm32f407vet6
