Continuing with its endeavor to deliver low cost micro controller hardware development platform, NGX has now launched a new low cost prototyping platform for LPC1768 series of mircocontrollers. LPC1700 are ARM cortex-M3 based micro controllers. The platform is named BlueBoard-LPC1768-H and costs only $32.5 BlueBoard-LPC1768-H is a breakout board for LPC1768 cortex-M3 based microcontroller. The [...]

NGX Technologies Bangalore, has launched a very low-cost and feature rich ARM7 evaluation/educational board. The product is named ‘BlueBoard-lpc2148’ and is based on the popular LPC214X series of ARM7 microcontrollers from NXP semiconductors. BlueBoard is an open-source initiative at realizing cost effective prototyping and solutions. Driven at present, by engineering and support from NGX Technologies, [...]

Somehow I’ve been sticked to NXP LPC2xxx series microcontrollers and left other brands behind. There are many major manufacturers of ARM microcontrollers. One of them that is worth to pay attention is Atmel with its AT91SAM7 (Smart ARM7) series. SAM7 series of microcontrollers have built in Flash memory and data memory as well. Core is [...]

New microcontroller LPC2478 from NXP company is based on ARM7 core with built in Flash memory and have built in LCD interface. LPC2470 has no Flash memory. LPC24 series have two high speed buses AHB to ensure independent work of peripherals like LCD, 10/100 Ethernet, USB and two channels of CAN. LPC24xx have reasonable low [...]

Firmware for AduC70xx ARM microcontrollers can be uploaded using built in boot-loader. To work with boot-loader Analog Devices offer to use small free program ARMWSD working under windows system. Program doesn’t require installation. ARMWSD communicates with AduC70xx via COM-port. Simple programming steps looks like this: Connect target board to PC COM port; Go to Configure->Parts [...]

As I earlier was writing about my home made ARM7-Base development board for LPC2148 It is time to write few words on how to use LPC2000 flash ISP utility. LPC2000 flash utility is a software which is used to program LPC2000 series ARM microcontrollers: LPC2101, LPC2102, LPC2103, LPC2104, LPC2106, LPC2106, LPC2114, LPC2114, LPC2119, LPC2124, LPC2129, [...]

Embedded software consists of various functions performing particular tasks. Before writing any ASM or C code it is good to draw algorithm flow chart. Flow charts are visual method of representing inner algorithm. It is easer analyze the algorithm and write the code according to diagram. The main parts of diagram: Fig 1. Simple series [...]

Finally got my LPC2148 RTC working on my development board. arm7 base development board for lpc2148 I am quite new to ARM microcontrollers, so I managed to make few tests using them by driving some peripherals and writing some test routines. First code I tried was simple LED blink program first lpc2148 arm7 microcontroller test [...]

All you know that microcontrollers have limited amount RAM and EEPROM. For instance ATMega128 has 4-Kbytes of RAM, 4-Kbyte of EEPROM. This may seem quite enough for some applications, but more complicated routines require more of RAM. And there is no compiler that can do better optimization on usage of ram than programmer. The main [...]
