I have question, regarding ETHERNET splitter, passive hub. I am designing hardware with LPC213X and ENC28J60 Ethernet chip . PC is going to talk from NIC to this controller TCP/IP (UDP) . Beside this LPC213X is going to communicate with modem which has Ethernet port . Also PC will be able directly talk to modem ( configuration etc. ) So basically 3 Ethernet devices communicating ( LPC2...

Hi, I seem to miss something with setting up PWM5 output - the routine below sometimes works, sometimes not (depending non additional code - this versions below currentlly does NOT work). Any idea what I miss to setup? Thanks for your input. Regards Herbert #include /* LPC213x definitions */ #define TICKS_PER_US 15 void io_alarm_out(u

Hello, Just a stupid question from someone who still not digged up through all those huge pile of datasheets and other documentation... 8-) Is it possible to use SSP peripherial of LPC213x for PS/2 keyboard/mouse interface? I now trying to figure this out, reading LPC user manual and all information that I found about PS/2 protocol, but maybe

Will the new real-time-clock in the LPC213x be able to wake the CPU from power down mode? I hope this is the case since it has external power and an external crystal...otherwise, the 2130 will continue to be a poor candidate for power-down operation as it will require an expen

Hi Friends, I just stated on a new development using IAR 5.11 compiler and LPC2138 micro controller. And used the code provided by IAR ARM/examples/NXP/LPC213x code to get started.=20 Could anyone please advise me on the following issues, 1. I was wondering whether can I the use the same files provided under "ARM/examples/NXP/LPC213x/config" directory Flash.icf, Flash.mac, RAM.ifc &...

Hi, I am new to ARM, Could some one help me to find the Sample Code Bundle for LPC213x Peripherals using IAR's Embedded Workbench for ARM 5.x. I found the sample code bundle the lpc2000Group for LPC2138. But it is written for IAR odler version 4.x Thanks Venu ------------------------------------

I'm working on a design with an LPC2148. However, the LPC2148 has a long lead-time in the US. So I'm going to use a LPC2138 until the LPC2148 is ready. The obvious difference is the loss of the USB interface. The rest of the device appears to be electrically and software wise the same. (The LPC2138 does have two 10-bit DACs instead of one on the LPC2148). Any other problems or issues ...

I checked and the Device ID for the lpc213x and lpc214x are the same. lpc2148: 196389 lpc2138: 196389 How can I tell the parts from each other by using the isp commands. Better yet, how does Philips tell the parts from their LPC2000 flash utility as it can tell a 2138 from a 2148, even though the IDs are the same. The datasheet I have for the 2101-2103 only has the device ID for the 210

Has anybody tried inputting an external 32.768kHz clock to the RTCX1 and RTCX2 oscillator pins of the lpc213X? Is it possible at all, since nothing seems to be mentioned in the documentation on this subject. BR Bisser ------------------------ Yahoo!

Hi Dave, It seems that S0SPCR has sprouted extra bits on the LPC213x and LPC214x. The CrossWorks LPC21xx header file was generated from the register description of an LPC2124 which doesn't have these extra bits. The next release of CrossWorks has header files for each LPC device to avoid these problems. For the time being can you modify your copy of LP

I am having a problem when trying to disable the JTAG interface on an LPC213X. I have a pulldown resistor attached to P0.31. On my JTAG interface, I apply 3.3V to P0.31 and everything works fine. What I have noticed, is that when my JTAG interface is not connected (p0.31 pulled low) I no longer recieve EINT0 interrupt on P0.16. Can anyone tell me if they have seen this behaviour? Or...

Can someone explain to me how I connect the RTC registers in a LPC213x to the time structures in ansi C. I have the RTC up and running but I would like to do some time calculations that require the time lib. I guess there are stubs that I have to program myself to connect the RTC with the C library time functions. /BR, Henrik ------------------------------------

I'm seeing some odd WDT behaviour - need a reality check please.... According to the UM : "Once 0xAA is written to the WDFEED register the next operation in the Watchdog register space should be a WRITE (0x55) to the WDFFED register otherwise the watchdog is triggered." My reading of this is that as long as the 55 is the next thing written into the WDT register space, the delay between w...

Hi, Did anybody have some experience with demodulating BPSK signal with LPC213X or LPC214X MCU. Our telemetry is receiving BPSK coded data from sensor with approx 2400 baud ( bit/sec ) rates . There is 100ms burst of data and 2.9 sec gap etc. Sensor is DC powered ( 12-20VDc ) with BPSK sinewaves signal ( 0.5V ) modulated on DC . Thanks Radim.

I'm just starting with LPC ( I have a LPC-H2138 board from Olicom) and at the beginning I'm unable to solve the following problem: I have an Timer0 set to generate interrupts. Timer works just fine, but I can't force the ISR to execute. Below is my code: #include #define LED 0xF0000000; static int timer0Count, timer1Count; int marker=3D1; static void PLL_Init(voi

Hi guys, Does anyone know if it is possible to achieve 115200 bps using the 'LPC2000 Flash Utility' with LPC2138 and XTAL=10MHz ? The maximum baudrate I'm able to use is 38400. Even 57600 bps is not working. I made a routine to test UART0 @ 115200bps and I can only use this baudrate properly when I adjust the fractional divider register (U0FDR - LPC213x/01 devices only) to get the minimum...
