A boilerplate project for Seeed Studio's XIAO-ESP32S3-Sense using the PlatformIO IDE and the Arduino framework.
Features:
- Takes care of initializing the hardware.
- Initializes the external PSRAM.
- Mounts the internal flash as a storage medium.
Partiotion Table:
The 8MB flash is partitioned as follows, there are 20KBs of space allocated as nvs key-value storage, an otadata partition, and two app partitions defined, 2MBs each, so OTA updates can be supported as well. And finally 3.93MBs of space is allocated to the storage partition that is available to the user to work with.
| Name | Type | SubType | Offset | Size |
|---|---|---|---|---|
| nvs | data | nvs | 0x9000 | 0x5000 |
| otadata | data | ota | 0xe000 | 0x2000 |
| app0 | app | ota_0 | 0x10000 | 0x200000 |
| app1 | app | ota_1 | 0x210000 | 0x200000 |
| storage | data | spiffs | 0x410000 | 0x3f0000 |
It is as easy as inheriting from the application class and overriding on_create and on_update methods.
Check out the example.cpp file, It's provided to help as a starting point.
Note: As mentioned, this example utilizes Espressif's Storage API, so if you're building from source don't forget to build and upload the filesystem image as well before the first use.
