I2C Read Number

Read one number from the specified 7-bit I2C address, in the specified number format.

pins.i2cReadNumber(0, NumberFormat.Int8LE, false);

Parameters

address: the 7-bit I2C address from which to read the number.
format: the number format. Formats include Int8LE, UInt8LE, Int16LE, UInt16LE, Int32LE, Int8BE, UInt8BE, Int16BE, UInt16BE, and Int32BE.
- Int stands for "integer", and UInt stands for "unsigned integer".
- LE stands for "little-endian" and BE stands for "big-endian".
- The number in each format name stands for the number of bits in the format.
repeated repeated start, true - don't send stop at end

The following example reads a number in big-endian, 16-bit, unsigned integer format from the 7-bit I2C address 32.

pins.i2cReadNumber(32, NumberFormat.UInt16BE, false);

This function is not supported in the simulator.
