Note:
(1) This project is based on the Linux 2.6.30.4 ported source code provided by Tianqian, driving the lrf020 wireless module, using the spi0 interface.
(2) This project uses the spidev source code and modifies it. Spidev provides a stable spi driver demo framework, you can copy includes/linux/spi/spidev.h, driver/spi/spidev.c, and modify and compile them by yourself.
(3) For other platforms, if you want to write a kernel driver based on the Linux spi subsystem model (not GPIO simulation or Here is a better method. Use the spidev source code, add your own protocol without touching the low-level hardware registers, and then rewrite the read/write method for the user layer to call.
(4) Based on The Linux SPI subsystem model kernel driver requires a deeper understanding of the kernel. Reading the Linux SPI documentation and source code is a shortcut to writing SPI drivers.
