Since juli 2005 we ask our Philips FAE and business contacts in germany for a date, when redesigned chips of the LPC2134/6 and the LPC2292 will be available. The bugs around the timer/match/pwm ISR issue and the bugs in the CAN controller have now turned into blocking points concerning the release of some of our projects. Every time we asked, we have got later dates, but not exact informati

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.

Hello, I have spend some time in getting the ADC on the move. The users manual states on page 198 that the ADC inputs are always connected to the I/O pins of the LPC. This is NOT correct. You DO HAVE TO use the PINSEL registers to connect the ADC inputs with the I/O connections. My users manual is release November 22 2004. If there is a more recent

Hi, I'm using the LPC213X and the PWM controller using PWM2 as a double-edge controlled output. It seems that no matter what I do, as soon as the GPIO pin (P0.7) is configured for PWM2, the output goes hard low. This is very undesirable for my application. I need this pin to stay high and I cannot seem to figure out if there is anyway to prevent this from happening. The following code is...

Hi, We've just discovered come characteristics of the external interrupt lines on the LPC213x parts (probably other parts as well, though not on the newer ones like the LPC214x), which I think is worth sharing with people here. Our basic requirement is to have an external signal generate an interrupt to signal a once-off event. We c

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.
