I am a novice. Recently, I have been working on a project. The customer asked us to make a 3.3V to 5V pulse solution. The output is required to have a driving capability of 200mA and a pulse width of ...
[i=s]This post was last edited by upc_arm on 2014-1-6 23:22[/i] The same program cannot be run on STM32 but can be run on MSP430. The two codes are very similar, but the status register read out by MS...
How knowledgeable are you? What kind of electronic device is this (the IC circled in the picture below)? It is used in the power supply. Is it an inductor?
I've seen it before, don't know what it was....
I used mcbsp to collect AD, and I need to put the collected data into the memory card, so I used the ping-pong cache method. Every time I collected a number, I used DMA to move it to the memory. When ...
