Freedom Logic Analyzer with DMA

From mcuoneclipse dot com: The FRDM-KL25Z Open Source Logic Analyzer based on SUMP presented here was already very useful with the added trigger support. But it was not capable to do a sampling rate above a few hundred kHz. That’s ok for slower probing, but not for anything with a higher speed. Using DMA (Direct Memory Access) instead of timer based sampling can remove that limitation.See the original post on “MCU on Eclipse” blog. There are many interesting projects with FRDM-KL05Z Board. Fore example, FreeRTOS on FRDM, DAC, OpenSDA USB, etc.
