# Arduino-ESP32 Example/Library Name ==(REQUIRED)==
|
|
|
|
==*Add a brief description about this example/library here!*==
|
|
|
|
This example/library demonstrates how to create a new example README file.
|
|
|
|
# Supported Targets ==(REQUIRED)==
|
|
|
|
==*Add the supported devices here!*==
|
|
|
|
Currently, this example supports the following targets.
|
|
|
|
| Supported Targets | ESP32 | ESP32-S2 | ESP32-C3 |
|
|
| ----------------- | ----- | -------- | -------- |
|
|
|
|
## How to Use Example/Library ==(OPTIONAL)==
|
|
|
|
==*Add a brief description on how to use this example.*==
|
|
|
|
* How to install the Arduino IDE: [Install Arduino IDE](https://github.com/espressif/arduino-esp32/tree/master/docs/arduino-ide).
|
|
|
|
### Hardware Connection ==(OPTIONAL)==
|
|
|
|
==*Add a brief description about wiring or any other hardware specific connection.*==
|
|
|
|
To use this example, you need to connect the LED to the `GPIOx`.
|
|
|
|
SDCard GPIO connection scheme:
|
|
|
|
| SDCard Pin | Function | GPIO |
|
|
| ----------- | -------- | ------ |
|
|
| 1 | CS | GPIO5 |
|
|
| 2 | DI/MOSI | GPIO23 |
|
|
| 3 | VSS/GND | GND |
|
|
| 4 | VDD/3V3 | 3V3 |
|
|
| 5 | SCLK | GPIO18 |
|
|
| 6 | VSS/GND | GND |
|
|
| 7 | DO/MISO | GPIO19 |
|
|
|
|
To add images, please create a folder `_asset` inside the example folder to add the relevant images.
|
|
|
|
### Configure the Project ==(OPTIONAL)==
|
|
|
|
==*Add a brief description about this example here!*==
|
|
|
|
Set the LED GPIO by changing the `LED_BUILTIN` value in the function `pinMode(LED_BUILTIN, OUTPUT);`. By default, the GPIO is: `GPIOx`.
|
|
|
|
#### Example for the GPIO4:
|
|
|
|
==*Add some code explanation if relevant to the example.*==
|
|
|
|
```cpp
|
|
// the setup function runs once when you press reset or power the board
|
|
void setup() {
|
|
// initialize digital pin 4 as an output.
|
|
pinMode(4, OUTPUT);
|
|
}
|
|
```
|
|
|
|
#### Using Arduino IDE
|
|
|
|
To get more information about the Espressif boards see [Espressif Development Kits](https://www.espressif.com/en/products/devkits).
|
|
|
|
* Before Compile/Verify, select the correct board: `Tools -> Board`.
|
|
* Select the COM port: `Tools -> Port: xxx` where the `xxx` is the detected COM port.
|
|
|
|
#### Using Platform IO
|
|
|
|
* Select the COM port: `Devices` or setting the `upload_port` option on the `platformio.ini` file.
|
|
|
|
## Example/Log Output ==(OPTIONAL)==
|
|
|
|
==*Add the log/serial output here!*==

## Troubleshooting ==(REQUIRED)==
|
|
|
|
==*Add specific issues you may find by using this example here!*==
|
|
|
|
***Important: Make sure you are using a good quality USB cable and that you have a reliable power source***
|
|
|
|
* **LED not blinking:** Check the wiring connection and the IO selection.
|
|
* **Programming Fail:** If the programming/flash procedure fails, try reducing the serial connection speed.
|
|
* **COM port not detected:** Check the USB cable and the USB to Serial driver installation.
|
|
