9.2.13. 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 <bsp/start-config.h>.
9.2.13.1. Clock Driver¶
The clock driver of the Cortex-M variants uses the ARMv7-M Systick. The older ARM7TDMI variants use the TMR0 timer module.
9.2.13.2. 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.
9.2.13.3. 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>.
9.2.13.4. 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>.
9.2.13.5. Network Interface Driver¶
Only a legacy network driver is support. For a libbsd base driver the platform support is missing, see if_lpe.c.
9.2.13.6. USB Driver¶
The USB host driver (OHCI) is provided by the libbsd.
9.2.13.7. Framebuffer Driver¶
For a custom framebuffer driver see <bsp/lcd.h>.
9.2.13.8. RTC Driver¶
There is a standard RTC driver available using the on-chip RTC module.
