RoseOnRails – LEDs and Rails

Yesterday night, Alexis managed to control the LEDs with a STM32 discovery.
We then pierced a rails segment and stuck the strip under it to see how it all worked out !

In fact, it was quite easy to have the strips fit under the railway, and the result is mesmerising … see for yourselves!

However, the way the LEDs were controlled for this test, does not enable us to have other threads in our programme because we need a quite precise timing to send information to the LEDs strips.

What we will do is :
Transfer our data (LEDs colors) to the external port of our development board through DMA and send the information from the board to the LEDs strips thank to SPI.
