Hi JDR04 From looking at files you have sent, It looks like you're running an old version of Flowcode, which had a bug of not transferring configuration settings to hex file and hence not loaded into target device. (I have confirmed this is the case since your hex file indeed does not contain the co...

No better. So we need to look at your compiler options (Build, compiler options, Programmer tab.) Use External program to set configurations must be enabled. (only thing I can think of its not enabled or you have not got -config on the end of -cs 2 -chip PIC%p in the lowest parameter settings?). Thi...

Hi JDR04
To do a screen grab , press control and prtscn, this will copy the screen to the windows clipboard ,then open a paint program( i use paint.net) and paste

Regards
Dazz

Happy new year too

martin (medelec) found a good selector tool and easy to use too

you could also use the ECIO range too

No,
12F683 can be programmed via ICSP and PICkit 2 in situ.
No additional stuff required.

Try setting Watchdog Timer to Off. Also disable Brown Out Detect.

Hi John.
You will need to go to 'Build' menu, select 'Compiler options', then click on the 'Programmer tab'.
Make sure you have 'Use external program to set configuration options' ticked:

Hi John, Two things. 1) If there is not a pull-up resistor connected from Pin 4 (MCLR) to +5V then you will need to go into the configuration screen and change Master clear enable from external to internal. 2) If there is no external crystal then you will need to go into the configuration screen and...

Hi John it looks like you have not set the Compiler parameters up correctly
Have you looked at:
http://www.matrixmultimedia.com/support ... f=68&t=787

Then checked all is set up correctly?

Edit: crossed posted with kersing.

It looks like your compiler settings are incorrect. Could you start by resetting them to default and try to compile the flowchart to see if that succeeds? If it does, change the programmer settings to those required for PICkit and try again. Make sure you change the programmer settings, not the comp...

Hello, Your middle picture shows the problem. The compiler is set to call the PICkit executable. That is certainly not right. First of all reset to the defaults and this should allow you to compile to hex correctly. Once you have this working you can start worrying about the PICkit settings in the &...

John,

Looks right, now you need to change the settings in the programmer tab (and only in that tab) to the ones used for PICkit.

Jac

Sorry was a typo, it should had said red lead i,e the lead connected to resistor/LED anode. It's to prove that LED and +5V are correctly working. Issues sounds to me that pickit is not configured to power device after programming has finished, which is what Dazz is saying. I totally agree. To leave ...

Hi from your last post it seems all is well, as with the pickit2 you have to select the vdd on to power the target board, the power light on the pickit is there to let you know the pickit2 is powered , the target light, lights when the vdd is selected on in the software and then provides power to th...

Hi John, Attached is a Flowchart that flash LED connected to port GP2 at 38KHz. (Period = 26us so its 38.46KHz to be more precise :) ) To achieve this more easily: 1) I have changed the internal oscillator from 4 to 8MHz (adding a C code block with osccon=0x70; changes osc speed). I was not sure on ...

Hi John, Attached is one way of achieving what you want. The configuration settings have not been set up, so that will have to be completed before trying on hardware. If there are a fair amount of switches, Then you can use just one analogue pin and use all the switches to be part of a potential div...

No problem John.
I have changed the LED connection just so the switches can be connected to the same port to simplify software.
Hop it goes well for you.

Martin

Hi John. The uninitialised error will occur if the bank of switches connected to port a are switch in such a way that the value of Read_Switch2 does not equal to any of the switch branch values i.e 1, 2 or 4 When that happens the switch component exits our of the default bottom branch instead of the...

Hi John Are you saying that the switch numbers and connections must be the same as the bit numbers of the port.ie Switch1 connects to bit 1 of the port. No not necessarily. You can connect any switch to any i/p pin, so long as you have the correct values set up in the switch component. I have placed...

Hi John, Ping..........the penny finally dropped. I now understand the switches etc. Nice one. Feels good doesn't it. :) First it would be best if you decide what hardware is required to adjust delays. I could be a variable resistor (potentiometer or trimmer) so you would use the ADC component. Or 2...

Hi John, No problem. Attached is a flowchart that will have an adjustable delay (two lots in fact) from 0 to 30.6 seconds with a resolution of 30ms It work by reading analogue channel and converting from 0 to 1023 (When you use ReadAsInt). The 0 to 1023 is multiplied by 30 to give a range of 0 to 30...

If you read the errors carefully you will notice the error is generated by the linker, not the programmer. I suspect the spaces in your filename are the cause of the error. Try saving the Flowcode file without spaces in the name.

Have a check in Compiler options/Compiler if the parameters are

For location:

C:\Program Files (x86)\Flowcode\v5\Tools\boostc\boostc_pic18_flowcode.exe

For parameters :

-v -t PIC%p "%f.c"


I think you set the "Programmer" params of PICkit in the Compilers params

Hi John,

It looks like you are missing spaces in both the location and parameters. Also, are you using 64 bit windows? If not remove " (x86)" from the location.
