Output modes There are two different output modes: Input modes There are four different input modes: Alternate functions The GPIO can also be configured as an “alternate function”. Used for specific hardware functions like pulse width modulation (PWM) or serial peripheral interface (SPI). The modes for alternate functions can be: Speed There are three-speed options:Continue reading “CH32V003 GPIO/Pin modes”

Programming CH32V003
To program the CH32V003 microcontroller, you will need a programming device that utilizes the proprietary single-wire serial debug interface (SDI). The WCH-LinkE (pay attention to the “E” in the name) is a suitable device for this purpose and can be purchased commercially. This debugging tool is compatible with the CH32V003 and other WCH RISC-V andContinue reading “Programming CH32V003”
Serial Plotter
My first try to make useful GUI application a Arduino Serial Plotter Simple serial plotter for Arduino and other devices to quickly visualize generated data. GUI is made in Python3 + Qt5 . Much work remains to be done. But this is a good start. https://github.com/taunoe/tauno-serial-plotter
C vs. C++: Bubble sort
I have identical bubble sort algorithm in C and C++. Same data and same computer. Experiment shows that C is twice as slow as C ++. In C it takes 124 processor clicks or 0.000124 sec. In C++ it takes 66 processor clicks or 0.000066 sec. C Bubble sort code: C++ Bubble sort code: https://github.com/taunoe/cpp-examples/tree/master/Sorting-algorithms/Bubble-sort
