-/***********************************************************************
- * This header file contains the mcp3008Spi class definition.
- * Its main purpose is to communicate with the MCP3008 chip using
- * the userspace spidev facility.
- * The class contains four variables:
- * mode -> defines the SPI mode used. In our case it is SPI_MODE_0.
- * bitsPerWord -> defines the bit width of the data transmitted.
- * This is normally 8. Experimentation with other values
- * didn't work for me
- * speed -> Bus speed or SPI clock frequency. According to
- * https://projects.drogon.net/understanding-spi-on-the-raspberry-pi/
- * It can be only 0.5, 1, 2, 4, 8, 16, 32 MHz.
- * Will use 1MHz for now and test it further.
- * spifd -> file descriptor for the SPI device
- *
- * The class contains two constructors that initialize the above
- * variables and then open the appropriate spidev device using spiOpen().
- * The class contains one destructor that automatically closes the spidev
- * device when object is destroyed by calling spiClose().
- * The spiWriteRead() function sends the data "data" of length "length"
- * to the spidevice and at the same time receives data of the same length.
- * Resulting data is stored in the "data" variable after the function call.
