# SPI Host Driver Example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example aims to show how to use SPI Host driver API, like `spi_transaction_t` and spi_device_queue.
This example aims to show how to use SPI Host driver API, like `spi_transaction_t` and spi_device_queue.
If you are looking for code to drive LCDs in general, rather than code that uses the SPI master, that may be a better example to look at as it uses ESP-IDFs built-in LCD support rather than doing all the low-level work itself, which can be found at `examples/peripherals/lcd/tjpgd/`
