The problem of STM32 ADC being prone to channel misalignment in sequential scan DMA transfer mode has been around for a long time. In the product I made, this mode was used because 7 channels were use
The method of identifying the three poles of the thyristor is very simple. According to the principle of PN junction, just use a multimeter to measure the resistance value between the three poles...
1 Introduction Traditional testing instruments are mostly completed by hardware circuits, which not only have single functions, but also have long development cycles and are difficult to maintain. Wit
PCF8576 is a character LCD driver/controller with I2C bus interface. It has 4 backplane outputs and 40 display segment outputs, so it can drive up to 160 LCD display segments. PCF8576 can be cascaded
[size=4] [b]Dimming is a very common function in lighting systems. For incandescent lamps, it can be easily achieved at a low cost. Dimming of LED lamps is somewhat difficult, but for architects and r
