To control I2C and SPI peripherals on Sipeed boards, you can use documented workflows to discover buses, scan devices, and read or write to sensor registers. The process requires verifying I2C and SPI pinmux configurations before running commands.

Yes, you can read and write sensor registers on a LicheeRV Nano using i2c commands. The board supports interrogating common sensors like AHT20, BME280, and SSD1306 OLED displays through reliable bus probing and device scanning.

SPI on NanoKVM boards requires proper pinmux setup to route pins correctly, especially when sharing pins with WiFi. You must verify pinmux configurations and perform safety checks before probing devices to ensure safe operation.

Yes, discovering and enumerating I2C and SPI buses on supported Sipeed hardware is a core feature. It allows you to detect available buses and scan for connected devices to simplify hardware testing and sensor integration.

An I2C device scan on MaixCAM may fail due to incorrect pinmux configuration, lack of i2c tooling access, or insufficient permissions. The Skill includes input validation and permission checks to ensure safe operation and prevent probing errors.

The best way to test hardware sensors on Sipeed boards is to power the board, verify I2C and SPI pinmux settings, and run detection commands to scan buses and read from sensors using validated, safe operation workflows.
