Report LRE 4x1 breakable RGB LED-Ring/Rotary-Encoder PCB bulk order in Bulk Orders Posted June 9, 2019 3 hours ago, TK. said: It shouldn't be a big deal to optimize the memory consumption. There are various places in MIOS32 where I already used DMA double buffers (e.g. I2S audio output). Nothing needs to be explored, just translation :) That sounds great! And... are you willing to do so? :-D Awesome work @Antichambre. Looks fabulous. Could you tell us where you have the translucent PMMA from? I buy my materials at TroTec. They have also awesome stuff!
