A few days ago, my boss asked me to debug the phase-locked loop that TI released not long ago, to see the performance first.The performance is quite superior. I wrote a frequency-dotting program to te...
Everyone says that the communication protocols of 485 and 232 are exactly the same, so the results of using TI's 485 routines should be the same. It just needs direction control in hardware. But my bo...
I have just started to study WinCE development recently. I used Win32 at first, and I feel it is difficult to get started, but I am willing to continue. However, I have some questions during my study,...
This was originally a small project, the purpose of which was to use the sht10 temperature and humidity sensor to collect the outdoor temperature and humidity values, and rely on the slave to send the...
Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[Details]
