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...

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 ...

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

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

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'm seeing some odd WDT behaviour - need a reality check please....

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.
