I've redesigned my little prototyping PCB for the DIP8 LPC810, adding a jumper to enable bootloading and a 3x1 connector for Flash Magic downloading (TxD, RxD and Gnd). The Gerbers have been sent off to ITead. If anyone wants one of the old PCBs, please send me an email with your address. The LPC810 doesn't seem to be available for sale, but you might be able to get some samples out of ...

Has anyone had any luck getting both I2C connections to work with the LPC2148? I've got I2C0 working fine now and I tried to set up I2C1 the same way (with the different pins of course) and I'm having some issues with it. I'm going to go try to analyze it with a scope but if anyone has any tips for that one I'd appreciate it. ------------------------------------

I received my LPC810 proto boards from ITead yesterday, assembled one of them, and had a couple of problems getting one of my LPC810 samples working. First off, a very simple test program that built OK with the LPC812 wouldn't link, giving lots of error messages: Linking Test.elf .text is too large to fit in FLASH memory segment .dtors is too large to fit in FLASH memory segment .ctor...

Hi, I am using LPC2368 to generate 16 square waves of independent frequency. The program works well in simulation but there are no square waves generated in hardware. UART0 is used to get values which determines frequency of each wave. Please help. I'll upload the program file named 4timers.c ------------------------------------

If during an I2C transaction (writing to a I2C display), I get a UART interrupt that has a possible I2C transaction itself (writing 2 bytes to I2C RAM), how do I handle that? Is the display transaction lost? Does the UART I2C transaction get locked because the display has control of the I2C bus just before the interrupt? Does the display's I2C transaction time out, drop the bus, and t...

Hello, I am running modbus server on LPC2148 at a baud rate of 19200. When a modbus client is continuously polling(send a request) at a rate of 1Sec, I see delay in reception of the commands. If i stop the polling and just issue single commands at random time i dont see any delay in processing those commands. Delay in execution of the commands happens only when other end is polling continuo...

Hi all, I use the LPC2365 micro with SMSC LAN8700 as Ethernet PHY. In order to reduce the EMI emissions, I would like to use this spread spectrum oscillator: http://www.digikey.com/product-search/en?x=3D15&y=3D17&lang=3Den&site=3Dus&= KeyWords=3DASSVP-R-C01-ND The Spread Spectrum Bandwidth is =B10.125% that corresponds to 50ps maximum jitter (the frequency is 50MHz with a stability of =B125...

Hi Group, I'm trying to use a Keil MCB4300 developper board along with crossworks. I downloaded the LPC4300 support package from Rowley and can create a little test project just fine. It compiles, but when trying to download this to the board the message pops up telling me that there is a "Target processor mismatch" which reads: The target processor defined in the project (LPC4357) o...
