USB not detected for PIC18F4550 chip

[karthickefy]

Hi Benz,
I developed a code for PIC18F4550 to connect USB serial to control the ports through Serial Command. But I couldn't install the Flowcode USB serial driver (.ini), and the Device manager shows an unknown USB. I installed the USB Serial Driver from the Flowcode Example page, but I still faced the same problem. Below is the picture. Please help me find where I made the mistake.


Thanks,
Karthick

Hello.
The issue is with windows not excepting unsigned drivers.
There is information on how to install signed drivers but you need to that at your own risk.

theese config words worked for me, with an external OSC 20Mhz, Flowcode V5;

config Words PIC18F4550 USB and external OSC.png (162.32 KiB) Viewed 1040 times

was succesfully recognised from windows 11 as universal USB Serial converter;

my project is simple but i dont find some working examples about,
i need to activate and deactivate outputs from an window on PC...i am studying this;
for PC i tested without succes (yet) Flowcode V10 App Developer(recognised COM from USB Pic18f4550 but didnt read or send nothing);

There are PC Developer (formally known as App Developer) & Web Developer examples here
They don't use PIC18F4550, they use ESP32 and Arduino Uno.
They might be able to help you to get going.

you are right, i haven't found any project that uses PIC18F4550/2550 to inspire from it; only with uses ESP32 which i'm not familiar...yet,
i'm already convinced that i should go for ESP32;
