NT-Shell Solution on NXP LPC55(S)0x Series
●The LPC55(S)0x is an Arm® Cortex®-M33 based micro-controller for embedded applications. These devices include:
■CASPER Crypto engine
■Up to 96 KB of on-chip SRAM
■Up to 256 KB on-chip flash
■PRINCE module for on-the-fly flash encryption/decryption
■One CAN-FD controller
■Five general-purpose timers
■One SCTimer/PWM
■One RTC/alarm timer
■One 24-bit Multi-Rate Timer (MRT)
■One Windowed Watchdog Timer (WWDT)
■Eight flexible serial communication peripherals, each of which can be a USART, SPI, I2C, or I2S interface
■One 16-bit 2.0 Msps ADC
■Temperature sensor
●The Arm Cortex- M33 provides a security foundation, offering isolation to protect valuable IP and data with TrustZone® technology.
●In embedded systems application, a shell function is much helpful to output log information and easy debug some standalone function API. Natural Tiny Shell (NT-Shell) is written by Shinichiro Nakamura. It is a C library for embedded systems, provides VT100 compatible terminal control feature, and needs only serial read/write functions for the porting.
●This application note describes how to integrate NT-Shell files on the NXP LPC5500 with SDK and how to use the shell function. NT-Shell will use the USART0 to print information and get command from terminal. We' ve also added control the led toggle status command based on the basic NT-Shell demonstration.
●The sample software is tested on LPC55S06-EVK evaluation board. The software is available for three IDE’s/toolchains:
■MCUXpresso
■Keil μVision
■IAR EWARM
