Is there a esp8266 simulator for testing code written on Arduino IDE?

Is there a good esp8266 simulator software that can be used to automate testing? Is it possible to get code written on Arduino IDE to run on these simulators?

Solution

  • As of Jan 2023...

    The docs for the RIOT OS (an IoT OS) explain how to compile and use an ESP8266 version of QEMU for Xtensa. The docs contain the compile instructions:

    cd /my/source/dir
git clone https://github.com/gschorcht/qemu-xtensa
cd qemu-xtensa/
git checkout xtensa-esp8266
export QEMU=/path/to/esp/qemu
./configure --prefix=$QEMU --target-list=xtensa-softmmu --disable-werror
make
make install

    Actually, the gschorcht/qemu-xtensa repo (last updated 2018) is a fork of the original OSLL/qemu-xtensa project, so you could use the original repo:

    cd /my/source/dir
git clone https://github.com/OSLL/qemu-xtensa
cd qemu-xtensa/
git checkout xtensa-esp8266
export QEMU=/path/to/esp/qemu
./configure --prefix=$QEMU --target-list=xtensa-softmmu --disable-werror
make
make install

    Unfortunately, that branch hasn't been updated since 2019 so it may not compile on very recent OS versions. For instance, I got an error: expected unqualified-id error while trying to compile on macOS 12.14. So, someone probably needs to fix those compile errors.
