I am a beginner in WinCE. The chip is PXA270. I need to use the interrupt IRQ_ALARM generated by RTC timing in the driver. I have established the mapping of IRQ_ALARM to system interrupt SYSINTR_RTC_A...
For my graduation project, the teacher gave me a question to make a wireless mouse pen. The question didn't say anything useful, nor what chip to use, as long as it can realize the mouse function. I l...
The picture above is the I/V conversion circuit I used. When debugging this circuit, I found that there were always some interference pulses on its output, as shown in the figure belowI checked it onl...
Hi, I have tried to program the serial port with two boards in the past two days. I have tried using C2prog and SDflash, but they both failed to connect. However, the DSP and PC use the 232 serial por...
I used the max743 power chip to design a 5v to positive and negative 15v circuit. The circuit schematic is as follows: At the beginning, when there was a load, I used a voltmeter to measure T4 and T3....
