Hi, Iam using the LPC935 and switch it to total power down modus to conserve battery power. DIVM=0 in my application. I am using the KBI interrupt to wake up...
Hi All, I am considering switching from Atmel AT89Cxx to Philips P89LPC9xx devices and I'm looking for a very easy and low cost way for in circuit programming...
Hi !! My ICP programmer it's work now. The cable with the ICP signals must be shielded and small. Now, my problem is to erase all memory LPC915. The FlashMagic...
Thanks for the replies. Both devices (http://www.teamfdi.com/pages/products_index.html and http://www.precma.it/lpcprogrammer.htm) seem reasonable and I may...
... While it sounds reasonably, it might fail because of the tight timing requirement of reset line "pulsing", especially in multitasking environments. And, of...
You are right Jan. As a matter of fact, I haven't studied detailed specifications of ICP yet. But I've used that sort of simple programmers for the Atmel...
I can tell you first hand - the timing for the reset pulses is critical, which bit-banged parallel port is not known for...especially going through the drivers...
Hi there, ... the ... I suspect that you have not cleared the KBI interrupt correctly, or you are returning with another KBI already pending. If so then the ...
All, At the risk of upsetting people who may or may not know better. I would suggest that instead of ICP you use the ISP protocol. It is serial based and all...
... Congratulations! Without attempting to understand your code, does this mean that you measure the length of pulses you are creating, so you know it went...
Rod, I couldn't find the files at the link you said, but if Jan's guess is right, it sounds a very creative and interesting solution to me too. I still haven't...
All, The link to the source file is http://cvs.sourceforge.net/viewcvs.py/lpc935-prog/lpc935-prog/lpc935-prog.c?rev=1.4&view=auto from the link below select...
Hi All, SDCC Is free open source (command line) Small Device C Complier which can compile 80c51 code (including Philips LPC900 series). Available here...
Joe, Here is my source file for the lpc935 it is most likely not complete and I have built it up over a few projects. But it might help it is a mixture of...
And for those who "may not know better", I count 15 LPC devices on my June 2005 Philips microcontroller line card that only have ICP programming capability!...
Thanks PM, this works! Clearing the KBI flag was the semi-last instruction of my ISR. By the way, how did you know that the interrupt system ensures that at...
Hi there Gertan, ... Had to search a bit but located the comment in the Family Hardware Description (Philips IC20, 1995) on how interrupts are handled. It ...
