lpc24xx (NXP LPC17XX/LPC24XX/LPC40XX)
=====================================
This BSP offers only several variants. The following variants support the
`Embedded Artits LPC4088 Developer's Kit <https://www.embeddedartists.com/products/lpc4088-developers-kit/>`_
and earlier board generations:
* lpc17xx_ea_ram
* lpc17xx_ea_rom_int
* lpc24xx_ea
* lpc40xx_ea_ram
* lpc40xx_ea_rom_int
They can be used as a base line for customization. The basic hardware
initialization is performed by the BSP. It can be customized via configuration
options and configuration tables. See also
`<bsp/start-config.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/start-config.h>`_.
Clock Driver
------------
The clock driver of the Cortex-M variants uses the `ARMv7-M Systick`. The
older ARM7TDMI variants use the `TMR0` timer module.
Console Driver
--------------
The console driver supports up to four on-chip UARTs. Initialization can be
customized via the ``lpc24xx_uart_probe_1()``, ``lpc24xx_uart_probe_2()`` and
``lpc24xx_uart_probe_3()`` functions.
I2C Bus Driver
--------------
I2C bus drivers are registered by the ``lpc24xx_register_i2c_0()``,
``lpc24xx_register_i2c_1()`` and ``lpc24xx_register_i2c_2()`` functions. The
I2C driver does not configure the pins. See also
`<bsp/i2c.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/i2c.h>`_.
SPI Bus Driver
--------------
SPI bus drivers are registered by the ``lpc24xx_register_ssp_0()``,
``lpc24xx_register_ssp_1()`` and ``lpc24xx_register_ssp_2()`` functions. The
SSP driver does not configure the pins. See also
`<bsp/ssp.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/ssp.h>`_.
Network Interface Driver
------------------------
Only a legacy network driver is support. For a `libbsd` base driver the
platform support is missing, see
`if_lpe.c <https://git.rtems.org/rtems-libbsd/tree/rtemsbsd/sys/arm/lpc/if_lpe.c>`_.
USB Driver
----------
The USB host driver (OHCI) is provided by the `libbsd`.
Framebuffer Driver
------------------
For a custom framebuffer driver see
`<bsp/lcd.h> <https://git.rtems.org/rtems/tree/bsps/arm/lpc24xx/include/bsp/lcd.h>`_.
RTC Driver
----------
There is a standard RTC driver available using the on-chip RTC module.
