It’s source code is located in ardusim sub-directory of the package.Īctully my long-term goal is to implement a simulator which acts like a http server and use HTML to render the simulation.Ībout hacking into arduino core files, taking digitalWrite as an example, I just added one line at the end like this: void digitalWrite(uint8_t pin, uint8_t val) Progress will always be published together with the release of IDE distribution as the simlator is useless without the IDE. I will keep working on this API-level simulator and the next hardware to be simulated will be LCD and SD device.
#Code blocks for arduino serial
This will open PC serial port COM5 and subsequential calls to Serial1 will act on the PC serial port. I have managed to run a sketch based on TinyGPS with a USB GPS receiver.įor example, to use PC serial port COM5 to simulate Arduino’s Serial1, you can do like this in the sketch: Serial1.begin(115200, 5) This is useful for debugging code dealing with any serial devices by connecting the device directly to PC via a USB-TTL adapter. For the hardware simulation, right now I have only implemented serial UART simulation with hardware serial port on PC. As is running on PC as a native program, the program logic can be debugged more easily within the IDE (by GDB, with break point, single step, variable watch etc.). As an Arduino sketch is built with AVR-GCC, the code can be compiled with x86-GCC with no modification and so are the most libraries. The idea is to re-write the underlying Arduino core files (and some AVR C routines) to simulate the behavior of a AVR chip (SFR, interrupts) and Arduino (digital/analog pins, serial UART). These are for building and running an Arduino sketch on PC. inoĪs you may have noticed (in the screenshot above, there are two simulator targets in every Arduino project created with the project wizard.
