HP 15c CE - New firmware update officially available!

[Uwe-001]

Experience report with the new firmware for the HP-15 CE:

I bought the programming cable online in the Moravia Shop for approx. 31 € incl. shipping. Shipping from the Czech Republic to Germany within a few days with DPD forwarder.
Firmware and instructions downloaded from Moravia, the recommended software SAM-BAv2.18 for Windows from the specified source. Installed on my cheap Lenovo notebook with Windows 11 Home, I was able to update the calculator without any problems. Only the Com Port "Bossa Program Port" was not displayed in the Windows Device Manager, but only a serial port without any further name, here Com 3. I used this with the Atmel software and after a few seconds the new firmware was installed and also verified. The calculator is running perfectly with the new firmware, but my model already had no or hardly any problems with bouncing keys.

Regards,
Uwe
