That's done the trick Steve, Thanks for your help.

Hi Steve,
Found this in default

$(compilerpic)batch\pic_xc8_comp.bat - Now it says toolchain not installed??

I think this happened when I opened a file from an older project from FC6 or even FC4

Good morning, I can no longer compile to HEX. Was previously working. I've opened a test project, selected a PIC and set CONFIG only. I get the following compiler message: Launching the compiler... C:\Program Files (x86)\Microchip\MPLABX\v5.40\mplab_platform\mplab_ipe\ipecmd.exe 16F1938 "C:\Users\HP...

Ok thanks, it's driving me nuts!

Hi, Can I set the zoom level for a project to 100%? It seems to be set at 75%. Every Macro opened has to be set individually to 100%.
Thanks, Dave

Hi Stefan,
Thanks for replying. It was the 256 that made me think it might be a bug. The input is a current measuring circuit using an op amp.
I removed the op amp and fed 0 to 5 V directly to the AD input and all works perfectly!
Fault is on the hardware somewhere.
Thanks again, Dave.

Hello,
This code works in simulation and the pot reads in 0 - 1023. On the hardware (PIC18F45K22) the LCD only reads up to 256 max. Is it me or is it a bug? Thanks, Dave.

Hi Benj,
The Timer component works well in this instance because the code is doing nothing else at this point so I can poll the 2 inputs for a change of state. The CCP code has the advantage of edge triggered interrupts. (INT pins are tied up with other things)
Dave.

Hi Benj, I've spent hours on this, adding bits in like the ADCON and ANSEL bits, trying to get it to work. It was definately pointing to AN3 originally. I removed the ADCON and ANSEL bits, pointed it back to AN3 and it all works! I'll add it back to the original program very carefully. Thanks for yo...

Hi all, I am trying to read an analogue input on AN3 on a PIC18F45K22 . Whatever voltage I put on the input, 0 to 5 V, always reads 255. (Macro "initialise" is part of a larger project but this bit won't work at all without it) I've tried a new PIC. Can someone have a look please? Thanks, Dave. ADC....

Have you had a chance to look at this yet Benj?
Thanks,
Dave.

Thanks Benj, that would be good.
Dave.

Hello all, I am trying to use the two Capture modules CCP1 and CCP2 on a PIC18F2550 to measure the time difference between two pulses. The rising edge of the first on CCP1 clears Timer 1 and the rising edge on CCP2 saves Timer 1 value to variables HIGH and LOW. This value is sent out over UART1. In ...

All updated and everything back where it should be. Magic!

Thanks again for your help.

Dave.

Just done a component search and it's now under "Misc" (was under "Displays" yesterday). I don't have a "tab" for Misc but at least I can find it now. What happened was this. I went to change the 4 x 16 LCD component in my flowchart for the 2 x 16 one. A box popped up saying updates were available f...

Hi Leigh,
Under Displays just LCD I2C (LCM1602) and loads of GLCD + 7 seg stuff.
No Hardware heading

Hi, just updated Flowcode 8 and the LCD Display components have gone (except for the I2C one).
Whats going on?

OK, This seems to compile: #asm movlw OSCCAL #endasm The XC8 compiler manual says "Note that this function is automatically called by the runtime start-up code (unless you have explicitly disabled this option,( see Section 3.7.1.14 “osccal”) and you do not need to call it to calibrate the internal o...

Hi all, I need to load OSCCAL with its stored value. Tried asm movwf OSCCAL in a C Box And got compiler errors: 31: __config("__PROG_CONFIG", "pic", 0x1, 0x3FEB); ^ (1386) unable to determine the semantics of the configuration setting "OSC" for register "CONFIG" (warning) PIC10F.c: main() 74: asm mo...

And all is now clear.
Thanks Benj.

Hi Benj,

Most of this makes sense to me with the help of the simulator. Struggling with these two lines
What is the *10 doing? Also the -'0'?

Thanks,
Dave.

Wow, I'm glad you only did a "simple" example Benj! It'll take me some time to get my head around that.
Thanks very much for taking the time to do it. (I may well be back with a few questions)
Dave.

Hi Benj,
Thanks for that. I'll have a read of the state machine info. Good point about making all variables the same.
Yes please, a simple example would be very helpful.
Thanks again,
Dave.

Hi all, I have an application where I need to read in parameters from an SD card to PIC variables. I want to write the parameters on to the SD card on a PC. I am thinking of using notepad to write the files and saving them as .txt files Say I have 2 lists of parameters saved as Type1.txt and Type2.t...

Hi, Can SCADA be used to make a PC interface to read / write to an SD card via USB to a card reader?
I would like to have data stored on an SD card for use with an 8 bit PIC but have the ability to update the card externally on a PC using a custom PC program (SCADA).
Thanks,
Dave.
