ARM7-32 BIT RISC PROCESSOR
Now I entered in to ARM processor through Philips LPC2148 controller.
It has lot of peripherals:-
ADC 10 bit 14 channel
DAC 1
RTC with alarm facility
PLL
PWM
USART 2nos
I2C
SPI
USB
TIMER with capture/compare
512KB FLASH
32KB RAM etc.
64 pin LQFP package
GPIO-PORT0-29 nos
PORT1-16 nos
CLK speed up to 60 Mhz with 12 Mhz external crystel.
Low power consumption (arround 500ma with maximum features)
Peripherals can be on /off independently for saving the power.
I am using bluboard with lpc2148,it is lowcost development board for ARM by NGX technologies.
programming the chip is easy because on chip bootloader is available with lpc2148.
WINARM IDE is using for software development.GCC compiler is utilized in this IDE.
Some of the driver modules I compleated are:
1.LCD 2*16
2.Dislaying RTC in LCD
3.Communication with PC through serial port(USART)
4.SD card interfasing and implimented file operation with EFSL module
5.DAC port used for generating Audio output.
6.MP3 player implimented with LIBMAD module and EFSL.
7.FreeRTOS tested in the board.
