### Configure the project
|
||||
|
||||
* Set the target of the build (where `{IDF_TARGET}` stands for the target chip such as `esp32`, `esp32s2`, `esp32s2` or `esp32c3`).
|
||||
* Set the target of the build (where `{IDF_TARGET}` stands for the target chip such as `esp32`, `esp32c3`).
|
||||
* Then run `menuconfig` to configure the example.
|
||||
|
||||
```
|
||||
```sh
|
||||
idf.py set-target {IDF_TARGET}
|
||||
idf.py menuconfig
|
||||
```
|
||||
|
||||
* Under `Example Configuration`, configure the pin assignments using the options `TX GPIO Number` and `RX GPIO Number` according to how the target was connected to the transceiver. By default, `TX GPIO Number` and `RX GPIO Number` are set to the following values:
|
||||
* On the ESP32, `TX GPIO Number` and `RX GPIO Number` default to `21` and `22` respectively
|
||||
* On the ESP32-S2, `TX GPIO Number` and `RX GPIO Number` default to `20` and `21` respectively
|
||||
* On the ESP32-S3, `TX GPIO Number` and `RX GPIO Number` default to `4` and `5` respectively
|
||||
* On the ESP32-C3, `TX GPIO Number` and `RX GPIO Number` default to `2` and `3` respectively
|
||||
* On the ESP32, `TX GPIO Number` and `RX GPIO Number` default to `21` and `22` respectively
|

* On other chips, `TX GPIO Number` and `RX GPIO Number` default to `0` and `2` respectively

By default, the example runs at a bit rate of 125kbits/sec, and the bit error should be triggered after the arbitration phase of each transmitted message.

|
||||
* Set the target of the build (where `{IDF_TARGET}` stands for the target chip such as `esp32` or `esp32s2`).
|
||||
* Then run `menuconfig` to configure the example.
|
||||
|
||||
```
|
||||
```sh
|
||||
idf.py set-target {IDF_TARGET}
|
||||
idf.py menuconfig
|
||||
```
|
||||
|

* Under `Example Configuration`, configure the pin assignments using the options `TX GPIO Number` and `RX GPIO Number` according to how the target was connected to the transceiver. By default, `TX GPIO Number` and `RX GPIO Number` are set to the following values:
|
||||
* On the ESP32, `TX GPIO Number` and `RX GPIO Number` default to `21` and `22` respectively
|
||||
* On the ESP32-S2, `TX GPIO Number` and `RX GPIO Number` default to `20` and `21` respectively
|
||||
* On the ESP32-S3, `TX GPIO Number` and `RX GPIO Number` default to `4` and `5` respectively
|
||||
* On the ESP32-C3, `TX GPIO Number` and `RX GPIO Number` default to `2` and `3` respectively
|

* On the ESP32, `TX GPIO Number` and `RX GPIO Number` default to `21` and `22` respectively
