Create driver linux

 · The development of drivers for Linux OS is possible only in C and assembler languages, but not in C++ language (as for the Microsoft Windows kernel). It is connected with the fact that the kernel source pieces of code, namely, header files, can contain C++ key words such as new, delete and the assembler pieces of code can contain the.  · The first task when programming the source files of a driver is to select a name to identify it uniquely, such as hd, sd, fd, lp, etc. In our case we decided to use mrv4. Our driver is going to be a character driver, so we will write the source into the file /usr/src/linux/drivers/char/mrv4.c, and its header into /usr/include/linux/mrv4.h.  · To write data to your device: spi_write (spi_device, write_data, sizeof write_data); The above code is independent of implementation, that is, it could use McSPI, bit-banged GPIO, or any other implementation of an SPI master device. This interface is described in linux/spi/www.doorway.rus: 5.

For example, Fedora prohibits including drivers that are proprietary, legally encumbered, or that violate US laws. And Ubuntu asks users to avoid using proprietary or closed hardware. To learn more about how Linux drivers work, I recommend reading An Introduction to Device Drivers in the book Linux Device Drivers. Two approaches to finding.
