I used HyperTerminal to connect to ARM9. There was no problem before. Today, I can only see output and not receive input! The HyperTerminal settings are as follows: COM2 bits per second: 115200; data ...
The FPGA uses Altera's EP2C8Q208C. The external clock is connected to the clk3 pin. The frequency is 27MHZ and is very stable. I use QuartusII's built-in ALTPLL to multiply the frequency, hoping to ge...
Today I carefully looked at the waveform sent by STM32F103RCT6 and found that when it is set to have a check, its serial port will send one less data bit. For example, if the data bit is 8 bits, it wi...
I want to ask you: I want to put the "Suspend" item on the start menu, which is similar to the "Run" position. How can I do this? Where is the code for the start menu? ? Thank you...
