Title: FT230XS Board to Board communication
Post by: kalesha on September 29, 2022, 08:22:09 AM

I have two boards which has FT230XS and interfaced with microcontroller and now I want to communicate those two boards using FT230XS as bridge

My doubt is how to connect two FT230XS signals (DP DM VCC GND) from one board to other board, we tried connected usb-usb cable and we drive voltage over VCC and found not communicating each other

Both boards working individually when connected to PC.

Hello,

FT230XS is a USB device and must be connected to a USB Host.

So you can't connect two of them together like that with the USB signals.

Is there any alternate way to communicate two boards like in one board USB device and other board has USB host IC so that the boards can communicate. Suggest one USB Host IC

Hello,

Does you Microcontroller already have UART or say I2C ports?
If so you could consider that method rather than using FT230X which would complicate your design by adding an additional USB Host.

If you require a USB Host capable of hosting FTDI devices then the best solution I can recommend is FT90x (https://brtchip.com/ic-module/product-category/products/ic/mcu-ic/?series_products=22) from our sister company Bridgtek.

See AN 360 FT9xx Example Applications (https://brtchip.com/ic-module/wp-content/uploads/sites/3/2021/07/AN-360-FT9xx-Example-Applications.pdf) section 2.23.6 USBH Example FT232.

Take a look at FT90x UART to FT232 Host Bridge, there is already a software example which can host FTDI devices including FT230X.
A video has been created which demonstrates this:

Bridgetek provide FT9xx Development Modules (https://brtchip.com/ic-module/product-category/products/modules/mcu/) and a free FT9xx Toolchain (https://brtchip.com/ic-module/ft9xx-toolchain/) for custom application development.

If you require support with this IC then please contact Bridgetek for support:
