Programming from uUSB - gen4-PA - GEN4-ULCD-50DCT

[Clement44]

Hello,

We're using the GEN4-ULCD-50DCT-CLB-SB. For prototyping, we program the display through the programming board gen4-PA via microUSB interface.

We would like to integrate this feature (USB programming from PC) on a custom board.

I saw on your gen4-PA schematic that you use the DTR pin of the CP2104 to create a RESET.
I don't really understand if RESET pin is used for programming or only for a hardware reset ?

I want to use an FTDI chip "FT230X", but this device don't support the "DTR" function.
Will it work ?

Thanks for your help,
Best regards.

Hi Clement,

Yes, the Reset pin is used for both programming and Hardware Reset.
