Dear colleagues, I am going to develop the Bluetooth driver of CSR BlueCore4-ROM on the wince platform (CPU is S3C2440) recently. I use UART to connect BlueCore4-ROM. This is my first time to use wire...
I am not very familiar with the interface of Quartus II. I have written source code in Verilog HDL language and want to implement logic functions directly through code generation. I don’t know where t...
I was on a business trip last week, and I started designing the expansion board right away when I got back at the weekend. Here is the system block diagram:...
I received the development board today. I feel that the packaging in the express box is very simple. It only contains the development board in an anti-static bag, and there is no anti-fall and anti-ex...
How to use an oscilloscope and its working principle How to use an oscilloscope: An oscilloscope, as its name suggests, is a machine that displays waveforms. It is also known as the "eyes of electroni...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
