There are three questions: Is there any difference between 232 serial port programming and 485 serial port programming under DOS? Can they be used interchangeably? What should I pay attention to when
I have installed the SDK, but I can find the path for which arm-linux-gnueabihf-gcc, but I cannot find the path for which arm-arago-linux-gnueabi-gcc. Please help me.
I used an oscilloscope to measure the P1.0 pin and observed the ACLK output. I found that the waveform was not a square wave, and the frequency kept changing from 8HZ to 26K. Could it be that my chip
Under WIN2000, I used DS to write a driver with interrupt No. 9 for an ISA card. I used SOFTICE to debug it. In INTOBJ, I saw that interrupt 39 was the interrupt service routine. I used idt 39 but cou
STC12C5A60S2 is going to use a 32MHz active crystal oscillator. What changes are needed in the crystal oscillator circuit and reset circuit? This is the circuit I drew. The crystal is connected to XTA
