[align=left][color=#000]I’m sure you’ve experienced the following scenario: Your engineering manager comes to you one morning and says, “We need to add connectivity to product ‘x,’ but we don’t want t...
I would like to ask you seniors, when I use IR2127 to drive high-end NMOS (circuit shown in Figure 1), the input drive signal of IR2127 is shown in Figure 2, and the waveform of the gate is shown in F...
A complete DSP program consists of at least three parts: program code, interrupt vector table, and link command file (or link configuration file) (*.cmd).The link configuration file determines the opt...
I just saw a post from a friend, saying that it is urgent to "boycott Kaixin and Xiaonei". At the same time, I heard my colleagues in the office sharing their experience of stealing tomatoes on Kaixin...
PB11 is set as output, and the capacitance on this IO port may be as high as 105. If no load is connected, the waveform can be output, but it is easily interfered by other signals, and there will be p...
