I wrote a top-level file of a module driving LCD1602 in Verilog language in Quartus 2. Why does the following prompt appear when simulating in ModelSim ?Note:E/examples/lcdd/lcd1602_test.vhd(154): (vo...
New product designs recommend the use of high-performance transceiver series, including CC1120, CC1125, CC1200. Both CC1120 and CC1125 support narrowband applications, and their corresponding RF perfo...
I recently started to work on my graduation project. I chose a 900MHz long-distance RF access control system. I have also found some information online. The main problem now is the implementation of t...
I made an ARM board, which imitates the principle of MINI2440, but removed some small experiments such as LED and buzzer. I downloaded MINI2440's SUPERVIVI using JTAG and wanted to check the serial po...
I have a strange problem and I don't know how to solve it. I recently want to improve the ID card reading problem of the company's POS vending machine. In fact, the program I have on hand can read the...
