I met problem on using the LPC2888 usb2.0 module. Some device can't be recognized by the windows xp, some can't run at high speed. I changed some crystal using...
Fanout is much less important nowadays because you are driving most inputs with voltage rather than current. (Current was important with original 7400-series...
Does anyone have or know of where I can find a USB project example for the SPJ tool. What I need is to be able to send data back and forth between the PC and...

Hi All, I soldered and wrapped a LPC 2387, then I connected Flash Magic 4.18 on the UART0 and I saw the flash display memory, tried a fill and it worked. I...
Hello all ! I am currently working on a product with a LPC2368 that uses the USB port as a (virtual) serial port for debugging information. The application...

Hi Paul, I talked to some of my friends and they all said that it is great that you offer personal licences. and also i thing the price is totaly affordable....
Hi all, Is it possible to use the EE_Demo_1_1 project in LPC2468 micro controller with uVision3 IDE to treat a part of the LPC2468 uC's internal flash as...
I have a lpc2148 witha Max3421E and programmed it to work with a printer but when I try to program it to work with a floppy via a CBI protocol, it doesnt work....
Hi Group, My current design so far only had a JTAG connector. After working a while with the LPC2378 and reading this group, I realize that programming the...
... Leon, Thanks for your reply. My concern is also the fact that aparently JTAG can't recover a board in all situations. I'm aware though that I would have to...
Hi What the best practice when working with an RTOS and ISR's ? Should i write all my code in the ISR , or should i only gignal a mutex in the ISR and handle...
Hi Sagaert, ... It depends ... Using an RTOS properly involves benchmarking the time required for each operation. So ... 1) Determine the priority of all...
I am using the LPC2148 and Keil development tool. Does anyone have a simple project that can demonstrate a USB Virtual COM? The demo I found from NXP is for...
Hi does anyone have any experience of trying to run run any of the LPC2000 range to achieve the lowest power consumption - I mean any real world current...
I'd be quite keen to see how this thread turns out also... One thing I have learnt is not to even bother thinking about using the built-in RTC if low power...
This stack works great. I've compiled it under gcc 4.2.2 and it works out of the box. Samples for COM, HID, mass storage devices, etc. I would think it...
Hi there. The pin can't be toggled by operations on the FIOPIN register. The pin can only be set or cleared by using the FIO0SET or FIO0CLR registers...
I've gotten my design down to 1.7mA with a LPC2148 in power down, but I have my RTC running. I haven't been able to find the source of why so much current in...
I have a couple of LPC2148 designs running at 400uA, with the RTC running. Turning off the RTC makes little difference, as I have measured the RTC at 20uA on...
... 1.7 milliamp seems too high, or do you mean microamps? Are you sure no clocks are running, or maybe a port pin is floating between logic levels?...
... Well, ok, not running, all clocks stopped. I gathered we were talking about sleep current here. Voltage? 3.3V of course. RTC crystal is 32.786kHz. Mike...
... Yes, we do exactly same on our production board. We even do not solder a connector for programming, we just leave PTH holes, and use simple berg strip to...
