Re: SuperPro CON2

I never heard of a regulated 7.5V supply, but I guess they could exist, more likely it is just a nominal 7.5V DC output transformer. If the board is in reset, something must be pulling reset low, what else do you have connected? Also do you really see 5V on the Arduino power connector (it would be g...

Memory map for C

From help line What is the memory map for SuperPRO PROplus in C? For C programs the memory map is controlled by the corresponding lpcXXXX.ld file in the lib directory. We take the stock files from the gcc distributions and make some minor edits. The sites for gcc have documents describing those file...

Re: HWPWM with different cycle times

Here is some code that I grunted out. I have checked the outcome for consistency with my digital o-scope. In short, the code can output simultaneous PWN pulse trains from pins 3 and 5 while changing the cycletimes on the fly (I just used some DO loops). I have noticed that only pins 3 and 5 work for...

Re: HWPWM with different cycle times

This is possible, but you will need to program the timer/match
registers differently. Though sketchy the details of those registers
is in the User Manual from NXP (link in the Help Files-> CPU details)

Re: HWPWM with different cycle times

In the "C-Tools", I notice that the HWPWM function is set up to use a single cycle time between all of the HWPWM channels. I was wondering if it is possible to have 2 different cycle times? I need to set up one HWPWM channel to one frequency (cycle time) and all the others to another frequency while...

Re: DHT11 Humidity & Temperature Sensor

I can't really tell you why any single IC fails, but it does happen. In the past there have been many reasons I've found that to happen, but normally it doesn't get investigated until there is a pattern. When we started shipping BASICchips, NXP had already shipped over 30 thousand LPC1114 chips to t...
