Hi everybody, I got a Maple Mini for x-mas...
My first project is SoftLed: an ambitious LED controller.
The system uses internal databases to store led information such as pin number, target brightness, time at which the brightness should be reached and current program number. When the target is reached the led looks for the next program and get new time and brightness. Leds and programs can be manipulated on the fly, in the program or from serialusb. A very simple task scheduler call the update of leds every 5ms, leaving plenty of processor for other tasks.
At the moment the serialusb works great to receive instructions from computer, but proves very unstable when trying to send information back to the computer such as the state of leds.
Help needed :
1. Is low-level USB communication more reliable than serialusb?
2. I am not sure how to use the pwm signals from the chip to power large led arrays...
Let me know what you think, I will post project link when ready.
