[i=s] This post was last edited by huanjun123 on 2014-11-6 15:19 [/i] I made a minimum system based on mega8. When testing, the IO port high-level output was about 1.5V and the low-level output was ab...
Hello everyone: I recently made 5 boards, and a strange problem occurred during the copy machine. The function of the board is to record data through the serial port, with an operating system. When ru...
Someone previously posted a document (vhdl) about FPGA phase-locked loops from the Japanese FPGA competition. I referred to it, changed it to Verilog, and used ModelSim to give the same simulation res...
I am currently working on hard disk data destruction, using the SST55LD019 (020) hard disk controller. When executing the Security Erase Unit command 0XF4 in the ATA protocol, the value returned by St...
My computer suddenly won’t start up! I can enter the BIOS, and the connection of the hard disk and memory is basically fine! When I start up, I enter the motherboard information interface! It should b...
