Hi everybody, The LPC2000 forum on Yahoo http://groups.yahoo.com/group/lpc2000/ had a posting today that I consider a huge step towards having 32-bit micros in almost all applications. An ARM7 device running a stunning 70 MHz starting at $1.47! It has strong communication features such as two 16550 compatible UARTS, 1 SPI, 1 SSP, 2 I2C, 8-channel 10-bit ADC and a Real Time Clock that can b...

We have developed a prototype board and software for the PC to program and test code for the Philips 89LPC901FN (8 pin DIP). Currently it only works with the 901 DIP because we think that will be the easiest chip to prototype circuits with for possible novices. The 901 does not have a hardware UART but can be bit banged. It uses a second 901 to talk to the program via serial port, (bit ...

1. I try to send message on CAN with 29 bit identifier, for example with walue 99dec (63 hex) and I receive message with identifier 0x00630000 it doesnt seem to be 29 bit but 11 bit??? 2. I looked int setting acceptance filter like in BlinkyCAN example from philips but it doesn't work: Does anyone have any idea why (in this example I'm using standard identifier of 11 bits)? // Setup ...

Dear Friends... For my project I am working with philips ARM7 based LPC2214 microcontroller and now I have to interface PCMCIA GSM modem with the circuit. I need to transmit some data by this modem because of its low cost and I need to go for near about 20,000 boards so interfacing PCMCIA is very benificial cost wise. The problem I am facing I don't know how to interface this modem with LPC2...

I need to connect a Commell LV-681 (ATI RS485M & ATI SB460 chipset, Turion 2x based) SBC to a 24-bit LVDS panel (LG-Philips LM150X08- TL01.)...

I need to connect a Commell LV-681 (ATI RS485M & ATI SB460 chipset, Turion 2x based) SBC to a 24-bit LVDS panel (LG-Philips LM150X08- TL01.) Unfortunately the LVDS output of this SBC is configured for 18- bits panels (I wonder who manufactures them.) Does somebody know some 18 to 24 bits converter? Thank you very much in advance for your help. Elder.

Hi! I need a i2c bus isolation with optocouplers or another technology. Google doesn't know interesting hits. Any hints other than the Philips solution with i2c bus drivers and optocouplers? An integrated solution as a cheap sockable DIP or SMD device would be great. I wonder that none of the big semiconductor producers is interested producing such a device many people need. Hey marketing en...

Hi all, Anyone some advice or experience on calculating the Xtal freq for a LPC22xx ARM7. I just don't find a correct value to generate stnadard UART baudrates (9600, 19200, 38400..) and standard CAN-bus speeds (125,250,500,1000) At this moment i have a 17.456MHz Xtal and this is working fine for the UART. For the CAN-bus, a multiple of 8Mhz should work fine. I tried to get to a...

hi, Im using KEIL PK51 for developing CAN based applications. Im using philips P87C591 model with in-built CAN controller.I have written a sample code for CAnopen and now want to include Multitasking feature to it. The RTOS provided by KEIL called RTX51TINY,doesnt seem to support CAN based functions.Iam intending to purchase RTX51 full,which has some CAN based functions.I searched the KEIL...

Hi all, Amontec just released a new configuration of the RAVEN on the Chameleon POD. This configuration enables the use of the rtck (return clock) for all ARM -s series. In fact, the ARM7TDMI-s ( and other ARM -s ), like Philips LPC21xx, use the rtck signal to control the baudrate of the JTAG. This means you can debug software running at very low frequency, but this means too that ...

I have started a new Yahoo! group to discuss the AT91SAM7 ARM CPUs. These chips seem to be divergent from the other Atmel ARM CPUs. They can function as MCUs with no additional chips, much like the OKI and Philips chips. Please check it out, join and contribute. Rick Collins www.gnuarm.com

hi, i am working with philips microcontroller LPC935 which is to be attached to I2C port expander. i have to write a code for this .As my device is configured as master receiver to read (i have to read only) the value or status of port pins . my question is that : Do i need to check for all 25 states of I2C bus from status register for my operation ?

Hi everybody, I am working for a company that develops an embedded storage device based on 2GB Compact Flash. CPU type is PQ2-Pro ( MPC8349 ). The flash is connected via USB interface using PHY Philips ISP1504. The operating system is Linux 2.6.13. The Linux image is built using LTIB (Linux Target Image Builder). The problem is the following: Linux kernel does not recognize the USB CF card...

I'm looking for compile ucos-ii RTOS port to the Philips LPC2129 with the GNU Compiler. The code available on www.micrium.com site is, instead, intended to be used with the IAR Compiler. First of all, I need to translate the assembly code for IAR Compiler to the GNU Compiler syntax (GAS, if I am not wrong), and I'm searching for a IAR Assembly User Guide but without success. Am I not able or...

hiiiiiiiii, i am interfacing LCD to my ARM microcontroller (PHILIPS LPC2138).i am able to program the LCD ,but it is uncertain. the problem is that when i reset my microcontroller or my development board the LCD is programmed and it displays the messages sent to it but when i reset it again it goes blank and after another reset it works fine again. so LCD gets programmed alternately. ...
