Request for STWLC89 Firmware

@Didier HERROUIN 

We currently use the WLC38, but wish to use the WLC89. Our sales rep already provided us with the full datasheet and schematic. He also has samples of the STWLC89 on order for us. However, there are no more evaluation kits available.

We have the firmware for the WLC38, but there is nothing in the repository for the WLC89.

We can probably figure out most things from the datasheet (includes reference schematic with BOM) as we have developed with the WLC38, but it would be a lot less effort with some reference information.

Can any of the following for the STEVAL-WLC89TRX kit (rev 2.5) be provided?

  • eval board reference design files 
  • gerber files
  • C-code, headers/firmware

Thank you!

Dear WirelessAether,

About wireless charging projects, ST has decided to reduce the mass market support.
Your distributor is supposed to help you for chipset selection and eval kit procurement.

Please open a case on st.com (https://www.st.com/content/st_com/en/support/support-home.html#), you ticket should be re-directed to me and I will be able to support you directly.

Best regards,

Didier Herrouin
