Hi! I'm a newbie, so sorry if I post a stupid question. This is my problem: I'have to work on a board with LPC2214 I try to run a simple code (like LED blinking) for fast GPIO PORT0 , but nothing happens, otherwise with standard GPIO PORT0 it works correctly. My trouble is that ARM is LPC2214/00 (without FAST GPIO) and not LPC2214/01. Using keil ULINK2 can I detect the type of ARM??? Thx --...

I'm having difficulty setting up a PWM output for a LPC2214 (P0.21 pin as PWM5 single-edge output) for a 50% duty cycle continuous pulse.

I can't find any reference to this in IAR or Philips documentation. The curious

Hello, I've just come across this on one of our PCBs. This is a proven board and code which a technician has just updated. He was manually manipulating P0.14 via jumper to access ISP, but had not removed power. After this the board will not start up after reset unless JTAG is present. Doing a reset then attaching the debugger shows the code to be stuck in a loop in the bootloa...
