Algorithm on GLiP block:
Today Guillaume has worked with 9 GLiP blocks, trying our algorithm in order to elect the leader among the network and give positions to each block. He succeed in this when the network is slowly increasing but when all the blocks come in a random way, it is still difficult to have a consistent network. There is still no acknowledge with the IrDA and when some packet is corrupted, the algorithm fails. We have to fix this soon.
Cédric has resolved his problem with UART4&5 for emitting packet. After some tests with Alexis, he found a good value for the resistance(4.7KOhms) to control emission power so that the blocks would communicate only to the neighbors. All potentiometers will be replaced by classical resistances.
Now I can drive the LED matrix using the new driver TLC5951. I can display a 8×8 pixel on the matrix but I have to fix some problems of intensity. We knew that blue is more powerful than red and green and we try to avoid this problem. For the moment, we can’t obtain a perfect white but I’m in a good way to fix this problem.
