Today I tried to receive temperature and pressure values on my phone. The measured values came from the onboard bmp180. In fact, it is very simple to develop with mbed, even if you start with a blank ...
I have a WinCE development board from Wenfeng, and its BSP is SMDK2410bsp. Since it comes with a MultiICE debugging tool, I want to use ICE to debug it. But I found that there is no axf file needed fo...
I would really like to use an oscilloscope to see the strength of each part of the circuit when static electricity surges into it.
It is good for verifying and debugging ESD protection circuits and ad...
