Simple circuits for USB to RS232 converter

[wakaka]

Hi there, i would like to build a USB to RS232 converter. Since there are USB PICs like 18F2550 and 18F4550, is there any sample circuits and firmware??

thanks.......

I found this https://pinouts.ru/SerialPortsCables/usb_serial_adapter_pinout.shtml
but dunno whether it works on PIC and AVR programmer or not.
Any other suggestions? preferably without the Surface mount FTDI chip?

build a USB to RS232 converter

There is a fully working example from Microchip included in the USBDEM board. It is the CDC example. Progamming language in C18. Run that example and plug in the USB cable would give you a COM PORTx emulated in the host (PC)

Use FT232. Quite simple to use.
