VCC和GND点太多了短路了该怎么找 引脚比较密的芯片和封装较小的电容,焊接不好时容易短路。有时候可能是锡珠或者铜丝之类的导电物体掉在了电路板上,正好VCC和GND引脚之间,导致短路。这种问题比较好解决,直接用烙铁处理一下就行。 2.刀割对于没有明显短路的板子,极有可能就是 2021-06-25 09:09:24 电路板上...
针对你提出的问题“output pins are stuck at vcc or gnd”(输出引脚卡在VCC或GND),我们可以按照以下步骤进行排查和解决: 确认问题现象: 首先,确认输出引脚是否真的被卡在VCC(高电平)或GND(低电平)。可以使用多用表(万用表)来测量这些引脚的电压。 检查电路设计: 核对电路设计图,检查是否有设计错误导致引脚...
Hi Mark,The question: There is probably a simple answer to this, but I couldn't seem to get there. Most of the ICs in the Library don't have Vcc and Gnd pins on the layout. Once the IC is in the schematic, how do I add a bypass cap to Vcc, or in general,
电路板上vcc正极还是负极 电路板上的VCC通常表示电源的正极。在电子电路中,VCC是电源电压的正极,而GND(地)是电源电压的负极。这种命名方式有助于区分电路中的电压极性。 在电子电路设计中,VCC和GND是最基本的组成部分 2024-09-06 14:47:05 电路中的GND和GROUND与VCC等符号的意思和区别详细概述 我们在看电路...
The manual only states that the board has 8 pins that are either a source/gnd pin and their location on the board. In VHDL would I assign GPIO_0[11] GPIO_0[12] as output pins? Translate0 Kudos Reply All forum topics Previous topic Next topic ...

NMOS chips used the designation Vdd and Vss for Drain and Source voltages (again positive and negative respectively). These days they've become fairly ambiguous.Most bipolar chips still use Vcc designations and GND if there is only a single supply, or Vee if there is a negative supply. Some...

Vcc and gnd in microcontroller on proteusAsk Question Asked 6 years, 5 months ago Modified 4 years, 6 months ago Viewed 11k times 0 The microcontroller power pins (Vcc,gnd) in the proteus are set to 5 volts by default. I have basic regulator circuit (my vcc 3.3 volt). How can I use...
I never thought of it until just now, but I wonder how much resistance is between the two grounds and two power supply pins. Dan Michaels says: This is most unfortunate. Exactly the other side of the "AGnd" are the oscillator pins, so this gnd pin makes a really great place to retu...
