Copyright (C) 2017, 2019 Sebastian Huber lpc24xx (NXP LPC17XX/LPC24XX/LPC40XX) ===================================== This BSP offers only several variants. The following variants support the `Embedded Artits LPC4088 Developer's 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 ` `_. 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 ` `_. 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 ` `_. Network Interface Driver ------------------------ Only a legacy network driver is support. For a `libbsd` base driver the platform support is missing, see `if_lpe.c `_. USB Driver ---------- The USB host driver (OHCI) is provided by the `libbsd`. Framebuffer Driver ------------------ For a custom framebuffer driver see ` `_. RTC Driver ---------- There is a standard RTC driver available using the on-chip RTC module.
