Memory Usage

Currently using PIC18F4525 with 48K flash, and 24576 single word instruction locations. 3968 Sram and 1024 Eeprom. When using Constants, I would like to understand where they reside - Which memory types are used When using variables, where are they stored? Secondly - Do you have an example for readi...

Re: PIC18f2553 clock

The Low program was enabled - The Extended CPU was not relocatable, and I presume that this refers to Extended instruction set enable (Which was enabled).
I set both of these to disable.
LED stays on for > twice the delay value.

PIC18f2553 clock

Hello Ben: Running PIC18f2553 with a 48mhz crystal. With a simple test -output on, delay 1 sec, output off - repeat. I find that the 1 second delay is 3 seconds (I can change that up to 12 seconds by adjusting CPU System Clock Post Scaler. The indication, to me, is that the configuration settings we...

C code

Can I get an example of code to be pasted into the C code icon for FC5 that shows a simple example to:

Look at an input
Turn on an output.


Thanks

PWM Deadband

I have a design to drive 4 output transistors configured in an "H" bridge arrangement. Switching these transistors is not trivial since turning ON the transistors needs to be delayed to allow the other transistors to turn off fully. This prevents short duration current pulses that can dama...

Serial interrupt disable versus Uart

It is not clear to me how the serial interrupt really works. If the interrupt is disabled, the uart can still receive serial data. I would like to know if the interrupt flag is raised even when the interrupt is disabled. This is a pivotal item since interrupts occurring while a macro call is in plac...
