The company has a mature architecture, but it has problems for me. Originally, LCLK was directly given by an external crystal oscillator. I entered the FPGA and then gave the 9054 chip through the FPG...
Millimeter waves usually refer to electromagnetic waves with a frequency band of 30~300GHz and a corresponding wavelength of 1~10mm. The operating frequency is between microwaves and far infrared wave...
As far as I understand, ChipWatcher should only allow one clock source to be selected. However, in actual use, it seems that even after selecting multiple ones, there is only one in the end. In this c...
Store 20 data consecutively at RAM30H, move them to 50H, store and count the total number of 05H in the data block. How to do it in assembly~~Thanks for your advice~~...
