Current setup:
LPC2468 uVision3 V3.1.0.903 with flash magic LPC2300.s as the start up file
We have a simple C file to set GPIO's as outputs and set them high. It compiled correctly and was programmed into the ARM successfully. The voltage measured on these GPIO's was a strange 2.3v where it should have been 3.3V. Some of the GPIO's do have a correct 3.3v, but not all of them. We then used a LPC2400.s startup file from the trial version of uVision4 to compile and program. The same issue persisted and, in addition, the software debugger would throw an error executing the startup file.
Using the above C file along with the trial verison of uVision4 and the LPC2400.s startup file, the GPIO's behave as expected.
We are using uVision3 because that is what our license covers and we have gone over the file size limits of the trial version. Our small school budget does not allow us to renew our license.

Colin; This has nothing to do with your particular problem but I wish to make a suggestion. Be pro-active and contact the Keil Sales people in the US. I'm not talking about a distributor but the actual Keil sales force. In the past, Keil has been very supportative of University programs with reduced license fees. I hope they still continue with their educational support. Bradford
We were given a student rate of $490.00 US which is well above our budget for a software IDE.
Colin; I can understand the cost problem as a student but a 90% discount for the U of F seems quite generous to me. After all that's less than the cost of one football helmut! Bradford
Are US universities really that impoverished??
As already noted, that's very much in the same ballpark as other disciplines would need to expect to pay for the equipment necessary to their studies - sports equipment, musical instruments, etc, etc,...
However, if cash really is that tight, then you should be looking at the free options available based on GCC, etc. They will probably take longer to set up but, once that's done, can produce perfectly acceptable results. Could be a student project there...
