spi.readblob(numberOfBytes)

Reads data from SPI port and returns it as a series of bytes

Availability

Device

Parameters

Name Type Description
numberOfBytes Integer How many bytes to read in from the bus

Returns

Blob — the bytes read from the SPI bus

Description

This method reads a specified quantity of data from the target SPI bus and returns it as a Squirrel blob. If the SPI is configured for full duplex operation, the same number of zero bytes will be automatically clocked out of MOSI.

Example Code

The code below provides a very basic example of interacting with an SPI device, initially by reading in eight bytes of data into a blob using spi.readblob().
