ACM32F070 series MCU supports 16 channels of touch key function, channel compensation, scan clock expansion, channel shielding, self-capacitance detection range is between 5~50pF, and the sensitivity
In some product designs that use cold plate cooling, sometimes due to negligence, the cold plate does not avoid the mark point, causing trouble in subsequent production.Today I will teach you how to u

[size=4]The working principle of capacitor voltage reduction is not complicated. Its working principle is to use the capacitive reactance generated by the capacitor under a certain AC signal frequency
In the most difficult time, with your help, I got through the difficult days. Life has ups and downs, ups and downs, thank you for your help, my best friend.
Although an oscilloscope probe may seem simple, it actually has a lot of details to it.
1. The first is the bandwidth, which is usually written on the probe in MHz. If the probe bandwidth is not enoug
