Hi

I have a flowcode Dev board but unfortunately it does not have an ICSP lead to connect to a breadboard and I don't think one is available to buy.

I have a microchip technologies Pickit 3 but it is different than the Pickit 2 as you have got to switch on the power supply so you can power the target device, this is simple when using MPLAB or other Microchip Technology software, however when using with flowcode there is nothing in the programmer parameters to turn on supply voltage, I just wondered if anybody has had this problem and found a solution...

Thanks
Acestu

Hi Stuart

Hmm thats interesting.
Ive only ever used my PICkits with the microchip software. The small standalone GUI for PICkit2 and the MPLAB IPE GUI for the PICkit3.
Never tried them with flowcode, thats on a long list of things to do

. Will be interested in the comments about this myself.

But I think that can be solved easily..you can make one for you easily...I also wanted to make one for me..If you want I can test for me and post for you. Obviously I will test in EB006 board as I don't have Dev board but the behavior for dev board will be pretty same as both uses same programming software PPPv3 and same hardware from programming.

Hi Stuart,
Here is the PK3 command line functions...But please don't expect Flowcode will be able to do all like original programming software. So detection of Vdd will not work as Flowcode can only use command line so it only be used for setting both VDD and VPP high or off.
You can see there is an option for V<voltage> which I beleive can be used in the programmer parameter tab..

Hi Enamul,

That is interesting, If I am right you are saying that this is a list of command line functions for the pickit3 but they might not work if added to the Flowcode parameters...

Well I will definitely look into that....

It is interesting that there is a v for voltage but nothing to set the voltage as it is variable ie 3.3 to 5 I think.

Thanks for the info

try the standalone programmer option for pickit3 http://www.youtube.com/watch?v=3EkNUa2nSDE

Posted: **Mon Nov 26, 2012 10:26 am**

I beleive you can get an adapter for the RJ45 port on the dev board to plug into the PICKit to reprogram the HP488 and EB006-00-6 and below.

I think you add the following to enable the PICkit 3 to power the board.

-V3.3

or

-V5

The number after the V specifies the voltage.

Thinking about it I have had a similar issue so i'm not 100% that this will fix the problem. Might be that my hardware was using too much current for the PICkit to cope correctly as the standalone software was not working either and I know this normally works ok.

Hi Benj,

I have just tried putting the -V5 in several different places in the programmer parameters line and tested each time
however I have not managed to get the pickit 3 to power the target so I think it must be something in the flowcode software....

thanks

Hi Fellas,

I have sussed it,

First you must add the -V5 or -V3.3 to your programmer parametrs like this:

-P%p -F"%f.hex" -V5 -E -M -Y"%f.hex"

Then you have to make sure that your Pickit 3 is in MPLAB mode, you can do this by opening the Pickit3 scripting tool gui (free to download from Microchip),

http://www.microchip.com/stellent/idcpl ... e=en538340

then go into the menu and click on "return to MPLAB mode", you will then be asked if you want to continue, agree and the app will close, you can now use with Flowcode.

Also in Flowcode, you may not want to always power your target device with the same voltage so you can save a couple of different setups ie one for 5 volts and one for 3.3 volts and one for no target voltage.

thanks

It will be of great help to many user.

That's great news!

Thanks Stuart for sharing that very useful information

Hope this info makes it on to the FAQ after being confirmed.

I followed the link for the scripting tool for the pickit 3 but the page does not seem to contain the link for the file (hopefully haven't missed it). I found a link, this is the one for V3.1
