I used Internal Register "Sec" in Keil Simulator for tracing execution time of my program and it gave precise execution time comparing with the time I measured on the target, Ashling's LPC2100 EVBA7, board. But I found it's not precise when I changed CPU speed on the fly, by

I've just bought a reconditioned Metcal solder station. It came with a selection of new tips including a 'Micro-hoof' tip made for drag soldering fine-pitch devices like the LPC2100 chips. It does make soldering them very easy - I just tack down two opposite corners (making sure the chip i

Someone mentioned the Nokia 3310 mobile phone LCD as a useful small graphics/character display on the PIClist. They are available quite cheaply from several sources so I've ordered one (about 16 GBP). The nice thing about them is that they have an I2C interface and will therefore connect directly to an LPC2100 device. I could have saved some money by taking the display out of my phone, of ...
