My hard drive is broken. It is not recognized. I removed the hard drive and found a capacitor, marked with a horizontal line with 34 below and 52 below. I posted this using another machine. I would li...
This book is based on OrCAD and Allegro in the currently stable SPB 16.6 version of Cadence, and introduces in detail the methods and techniques of using SPB 16.6 to implement schematics and high-spee...
When you need to transplant the algorithm you have written to the DSP development board and run it well, what work needs to be done? The following is divided into two parts. The first part is transpla...
Recently, I used 89C2051 to drive CCD, and the crystal oscillator used was 12M, mainly to control the timing of P10, P11, and P12. I needed to assign values to P10, P11, and P12 continuously, and assi...
I followed the KEIL 2 tutorial. My COM port is COM5. I checked it on the computer and it is definitely correct. Then I set the crystal oscillator to 11.0592 and the baud rate to 38400. Why can't I con...
