The foundation of special light sources, color display and other industries is the restoration and transmission of color, which belongs to the category of light source photometry and colorimetry in th...
In circuit design, we usually only care about the quality of the signal. Due to the limitations of simulation analysis software, SI simulation research is often limited to signal lines, and the power ...
How does DSP2812's SPI read optical encoder information? The problem now is that SPI sends control instructions to the optical encoder, the optical encoder can feedback information, and the oscillosco...
During this period, mpy has made many improvements to the STM32L4, STM32H7 and other series, so I wanted to try whether the DFU mode is normal. After recompiling the new firmware, I found that the DFU...
