Dear all, I have built a microcontroller development board for LPC2124 and have used a USB interface for programming the device since my PC and laptop both dont have any COM port connector. I have used FTDI's FT232BL chip for the purpose. When connected to the USB port the PC detects it as a USB to Serial converter and treats it as a virtual com port and assigns it a COM port number. ...

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'm still struggling with getting uIP to work on LPC2378 (Olimex LPC2378STK board). I have got ARP working, but when I send a TCP packet the PC shows a checksum error. I've gone through Paul's code for LPC2124 which helped with some structure packing issues, but unfortunately I started with the latest version of uIP which has changed quite a bit from that. I have checked with the FreeRTOS ...

I have been excited about trying the LPC2114 and LPC2124 parts (and similar parts) and notice in the users manual that when certain pins are assigned certain functions, other pins cannot be used for general IO etc. I am used to Microchip and AVR type parts where any pin can pretty much be assigned to be used as general IO or the alternate
