I'm using LM3S9D90 recently, and the ADC uses high-speed conversion (is 500K conversion speed considered fast?), so I use DMA to move data. There are two points I don't understand: 1. What is the DMA ...
[align=left][color=rgb(85, 85, 85)][size=3] When using C2000, engineers often say that the chip simulation can run, but the stand-alone run cannot run; or when debugging, reset the chip > run, and fin...
As the popularity of telephones increases, more and more families have residential telephones, but the utilization rate of most residential telephones is very low. It is economical and practical to us...
I made a simple digital controlled DC power supply based on MSP430F149. The output voltage can only be 0~4.95v. The design requirement is to reach 0~9.9v, but the ones I found online can't quite meet ...
I am about to graduate, and I just found some unopened development boards: LM3S811 sells for 100, c2000LAUCHpad sells for 50, and the 430 one sells for 15. If you need it, please contact Ma Huateng: 6...
