Hi.
I made a simple program for the microcontroller pic18f4550 and pickit3 + flowcode7,
but see the error when the firmware of the chip.
What could be wrong in my case.

Have you connected pin 31 and 32 to ground/power as well? If not the device might respond unpredictable.

Looks to me like programming has failed during the verify stage.

Programmer to target power is enabled - VDD = 3,250000 volts.

To program the 8-bit devices that are designed for 5V you need to be powering them at 5V. I've had similar problems programming the 16F and 18F devices at 3V3. The 16LF and 18LF devices on the other hand cannot be powered at 5V and should program fine at 3V3.

I found a power supply at 5V,
and connected it,
also connect the contacts 31 and 32,
the chip is programmed, but there is a window

Hi

C:\Program Files\Flowcode 7\tools\mLoader\mLoader.exe -chip 18F4550 "C:\Users\Public\DOCUME~1\Flowcode1.hex"

What are you using now for programming mloader with a Matrix programmer or PICKIT
clearly your setting as programmer are for mLoader not PICKIT ,the window you are seeing is looking for mloader and the relevant programmer

go to build>>> compiler options>>> programmer and enter the path for PICkit3 as powered for external powered also make sure you have entered the Microchip IPE path for example

Hello,

It looks like you have entered the PICkit Programmer settings in the Compiler tab.

Launching the compiler...
C:\Program Files\Microchip\MPLABX\v4.05\mplab_ipe\ipecmd.exe /P18F4550 /F"C:\Users\Public\DOCUME~1\Flowcode1.hex" /TPPK3 /M /OL

Flowcode does the following steps.

Compile -> Compiles C code into object code or .hex code.
Link -> Assembles object code into .hex code on some devices.
Program -> Programs .hex file to device.

For your compile stage you are calling the PICkit, the programmer stage is still calling mLoader.

Hi.
I changed the compiler and the programmer.
then came the error L
next, I changed the FILE PK3CMD.exe in the folder
C:\Program Files\Flowcode 7\tools\PICkit3
Programmer pierces program
but the led never flashes.

As far as I know,
after flashing I have to press the button on the programmer pickit3,
further the microcontroller to start the program?
Or do I need to check with a multimeter the contacts and check if he gives voltage with a period of 1 second.
the led is reversed (polarity),
but the LEDs are not.

It looks like chip has been successfully programmed.
Issue could be configuration settings or/and hardware.
We would have more of a clue if you posted your flowchart.


Martin

this is my circuit on a development Board,
voltage 33 contact outputs about 1.4 V
I'll try to install an older version flowcode
or to flash microcontroller using mplab

As I have previously stated, issue could be your configuration settings?
If your not willing to post flowchart then we are unable to determine if that is the case or not.

This is not the compiler. The compiler would have a C file as input, not a HEX file.

Yes,
You're right.
The whole thing was in the settings of the flowcode and programmer.
I installed version 6 of the program
and began to change the settings of the programmer, the compiler and the linker.
the LED flashed.
now I look at him and am happy.
