COM Port Issue...

[DaddyWarhammer]

Project requires COM port to communicate with M5Stack. My Win7 computer has no COM ports. Is there a virtual Serial port driver that will work?

Hi,

Like any other device, using an M5Stack with a PC (to flash or program it) requires the installation of a driver. This is explained in the documentation. Please take the time to read it carefully. That's why it's there.

Problem is, when I install the drivers, Windows Device Manager flags the entry and gives an error 52. After examining the certificate, it appears to be expired.

Ok, well, this is an operating system issue due to your Windows version and settings. This is not an issue about my projet. I don't work under Windows, but take a look at this link :

https://www.wintips.org/how-to-fix-windows-cannot-verify-the-digital-signature-for-this-file-error-in-windows-8-7-vista/

It explains how to bypass and disable the Driver Signature Enforcement. May be this tip works. Note that, Windows 7 support has been ended for almost 3 years.

If this does not work, contact M5Stack. I can't help you install the M5Stack device. I don't develop drivers, just firmwares who work on M5Stack.

OK, thanks - I'll try that. I think, ultimately, I'll need to upgrade to a new laptop and use the newer universal driver M5Stack has on their site.

Anyway, I do appreciate your quick replies and I can't wait to get the code running! Regards, Paul.

Ok Paul. I'm sure you'll fix this problem. Driver issues are always a pain to solve, i know 😔 Let me know if you have any other problem. I will try to do my best.
