A solar-powered airplane prototype completed its maiden flight last week, ushering in a new era of fuel-free, carbon-free flight. The company behind the prototype, Solar Impulse SA (Lausanne, Switzerl...
I'm wondering, STM32F103ZET6 obviously has a large-capacity FLASH chip. According to the manual, the startup code should use HD (large capacity). I have been using Keil before, and the startup code is...
I want to ask about the chip select CS among the four pins in SSI. My question is, when using the SSI of LM3S, using the library driver, do I need to care about this CS, is it pulled high or low accor...
I used to work on web and have some basic knowledge of C. Now I was suddenly transferred to the embedded department to learn embedded systems. I have only read for two days, and in the afternoon I was...
