1This demo shows a simple Renode-ArduinoIDE integration.
2
3It sets up the simulation, preparing the platform and loading
4samples into the sensor's buffer and waits for ArduinoIDE to
5load the binary.
6
7Currently the setup is prepared for a patched TensorFlow Lite magic_wand
8sample compiled for the Arduino NANO 33 BLE platform.

10The patch changes the UART output device from the default USB serial
11(not currently supported in Renode) to the hardware UART0.
12In order to do that, modify the `debug_log.cpp` file located in
13the `Arduino/libraries/Arduino_TensorFlowLite/src/tensorflow/lite/micro/arduino` directory
14and define `DEBUG_SERIAL_OBJECT` as `Serial1` (instead of `Serial`), e.g. with the following command::
15
16 sed -i'' '/#define DEBUG_SERIAL_OBJECT/s/(Serial)/(Serial1)/' ~/Arduino/libraries/Arduino_TensorFlowLite/src/tensorflow/lite/micro/arduino/debug_log.cpp
17
18With this change, you should see the following output on uart0 when running the simulation::
19
20 bytes lost due to alignment. To avoid this loss, please make sure the tensor_arena is 16 bytes aligned.
21 Magic starts!
