Curiosity Nano pic18f47k42 does not work .

[ahmetimanli]

How can I connect my Curiosity Nano PIC 18F47K42 device? When I connect it via USB, it doesn't appear in the programming port list. I also want to use it for debugging. I tried with Pickit 5 as well, but it didn't work. I would appreciate your help.

Hi

Not used it, but I would start by seeing if it appears under device manager. Perhaps Port or USB devices?

In Device Manager, under Microchip Tools, I see it listed as "Curiosity Data Gateway". It also appears as "USB Serial Device 11" in Device Manager.

Hi

Anything related under Ports?

Hi

Does the green power / status LED illuminate when you plug in? I'm guessing yes as your PC is "seeing" the board.

I don't use MPLAB (very much) but it is supposed to automatically recognise the nano development board. You could perhaps try and open the IDE menu and then go to the Window > Kit Window and force a rescan of connected boards?

Have you tried a different USB cable / port?

Hi

Via Google Translate from Turkish

Hello. I am selecting the PIC18F47K42 as the processor and trying to load an empty program. Upon compilation, it returns the following error:
Error returned from [xc8.exe]

C:\ProgramData\MatrixTSL\FlowcodeV11\FCD\PIC\batch\pic_xc8_comp.bat reported error code 0x1

It is as if it doesn't recognize the processor at all.

Which version of Flowcode ae you using? I ask as older versions may not support your chip.

I'm using Flowcode v11 Pro. I upgraded to version v11 specifically for debugging and troubleshooting. Shouldn't Flowcode v11 automatically recognize the Curiosity Nano board? I think it should be like the Arduino Uno. When I plug it into the USB port, it should be recognized so I can install programs and use the debugging features.

Hi

The board is supported in Flowcode v11. Does Flowcode offer a programming port option to select for it (Build > Project Options) ?

If not then your PC isn't recognising it. Any yellow exclamation marks under Device Manager or the like?
