OpenOCD installation The Open On-Chip Debugger (OpenOCD http://openocd.org/) aims to provide debugging, in-system programming and boundary-scan testing for embedded target devices. If you using Ubuntu or any Debian like OS, OpenOCD could be installed by running following command: sudo apt-get install openocd Read more…
Sometimes there is a need to visualize data from serial port in real time, like I had in my USB Accelerometer sensor. The goal can be reach hard way by writing your own software but there is no need to Read more…
Nowadays everyone has accelerometer sensor in its own smartphone. It’s there for several reasons. First of all it’s used for detection of screen orientation relative to the gravity field. This is the sensor which gives your phone information when the screen Read more…
LED diodes are non linear elements whom I-V characteristic depend from many external parameters such as temperature and manufacture. Mathematically I(U) dependence is described by Shockley diode equation. Unfortunately this exponential dependence, after adding resistor in series, becomes implicit function Read more…
