LPCOpen Platform for LPC18XX/43XX microcontrollers  18XX43XX
LPCOpen Platform for the NXP LPC18XX/43XX family of Microcontrollers
LPC43xx M0 core tick function using RITimer
Note
This driver adds support for the RITimer for the FreeRTOS tick on the LPC43xx. The M0 core in LPC43XX series of controllers does not have internal systick timer, so the RITIMER is used to generate the RTOS ticks.
