STWBC86 aplication

[DEIQO]

Hello,

I am currently working on the implementation of the STWBC86 chip, following the STEVAL-WBC86TX as a guide. If we want to develop a PCB with the STWBC86 chip, is it possible to load the initial configuration by connecting the PCB via I2C with a USB converter to the computer? Or is external hardware, such as the STM32 development board, required to load the configuration onto our PCB?

Thank you in advance for your attention.

Hi Deiver

for mcu please refer to this link

SW I2C driver on Github https://github.com/STMicroelectronics/STWirelessCharging-C-Drivers

for computer, you use usb-i2c dongle

STEVAL-USBI2CFT Dongle

• DB5077USB to I2C evaluation board for interfacing wireless applications with PC GUI tool
•  
• UM3226Versatile USB- I2C bridge for communication and programming of ST wireless charging IC
•  
• STEVAL-USBI2CFT GERBER
•  
• STEVAL-USBI2CFT BOM
•  
• STEVAL-USBI2CFT SCHEMATIC

Thanks for responding.

Yes, it turns out that what we want is to replicate the STEVAL-WBC86TX and just remove some things from it, but we see that it comes with a configuration using the FT260Q chip that would be the U3 (in the image), which they use for I2C Communication, converting it to USB- C and from there to the PC. I would like to know if with this same STEVAL chip we can upload the initial configuration of the new board.

yes 

it is same with STEVAL-USBI2CFT Dongle chip
