Can't see anything clear on the video. Not sure what value it has.

V7 Programming a (new) chip PIC18F2553 creates compiler error message indicating:

1.Board voltage too high
2.Board voltage too high
3.Flash memory not verified - may be due to code protect.

FINISHED

Chip is not programmed.

Flowcode 5 programs these just fine. Can you investigate?

I made a few changes and empirically ended up with Fosc/4 and 6 cycles acquisition time. Certainly got my analog acting more realistic.
If you wouldn't mind detailing me about the values - Is it more beneficial to be slower?

Thanks much - I can take it from here.

I had set the extended instruction set to enable in an effort to resolve the analog issue. What I'm saying is that the problem persists either/or extended instruction set enabled or disabled.

Any time line on having this resolved?

Not sure how this forum works - Is anyone looking at the detail I sent for review?

FLOWCODE 5

I have the 18f26k80 connected and running a serial display. I'm reading AN0 on pin 2 of the chip. My meter reads from 0 to 5 volts. The display show 4095 (full bore) and does not change. This pic chip has configuration bits for differential analog inputs, and I suspect that these bits are not set pr...

Didn't get a response for my post - Ended up getting a PICkit 3, saving the flowcode file an a hex format and dumping it into the PIC18f26k80 vis the required 5 pins on the chip. Now I don't have to remove the chip to program.

Let me know if anyone has detail for this repeat post: Hello: Re - Flowcode V5.5.2.1 (30.01.2013) EB-006-00-8 Programmer USB and power supply connected I have been using the EB-006-00-8 programmer for about 7 years.

Or in the case of more than 2 arrays - One would need to state If pointer is >255 AND < 512 then use array 2

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...

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.

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...

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

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 damage the tra...

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...
