For the crystal oscillator circuit, I used an inverter (74LS00) with a crystal oscillator, two small capacitors, and a large resistor. I used a typical circuit, but it doesn't oscillate on the oscillo...
[i=s]This post was last edited by paulhyde on 2014-9-15 09:20[/i] It's so strange. I looked at Heilongjiang and Shaanxi B questions. They both recommended 12 or 13 teams to enter the national level. I...
I am a novice in Ethernet. I recently read the MCB1700 easyWEB example code under KEIL and I don't understand how the function void CopyFromFrame_EMAC(void *Dest, unsigned short Size) is implemented. ...
