Lecture Notes
8051 Microcontroller :
8051 microcontroller is designed by Intel in 1981. It is an 8-bit microcontroller with 40 pins, 4KB of ROM and 128 bytes of RAM storage, two 16-bit timers and 1 UART. It consists of are four parallel 8-bit ports, which are programmable. An on-chip crystal oscillator is integrated in the microcontroller.
LPC2148 Microcontroller :
The LPC2148 microcontroller is designed by Philips (NXP Semiconductor) with several in-built features & peripherals. Due to these reasons, it will make more reliable as well as the efficient option for Embedded system Designers. LPC2148 is a 32-bit microcontroller based on ARM7 family.
Real Time Operating System :
A Real Time Operating System(RTOS) is a software component that rapidly switches between tasks, giving the impression that multiple programs are being executed at the same time on a single processing core. Key feature of RTOS is that it reacts to input within a specific time period.
