I have an SP200S programmer. I would like to program some pic chips PIC6B595N and AT24C256.
I have been directed to the Willar programmer to do this.
Would it be possible to connect my windows 10 computer to the programmer and use the software to do this?
Is or when will the programmer be available?

Answer by Alex Urbach

You need to have the correct drivers and the correct port set in the application. With all the devices attached and the software started, go to Start > Run > devmgmt.msc. Expand Ports and LPT then right click on Silicon Labs. Switch to Port Settings tab and click on Advanced. Choose COM2 or COM12 and then reconnect again and everything should work properly.

I have purchased a programmer marked as SP200SE. I have downloaded a .rar file which contained a driver for Windows XP and an application. The driver instalation appears in the "Programs" in the start menu "PL-2303 USB-Serial Driver" and in the System > Hardware > Devices > Other devices as USB2.0Serial shows an error.


When you run the application it works and is in English but shows the error "failed to connect". I can't find any thing that helps on the Internet. Is there anyone there with a solution?

Answer by Alex Urbach

The driver might not be installed properly, therefore the error shown as Failed to Connect. This could be due to compatibility of the driver with the version of Windows you're currently using.


Try forcing a manual installation. Go to Device manager and right click the item then choose Update Driver. Point the driver installation window to the folder with the INF files, or choose the INF file manually, then continue with installation. While installing, Windows will give you a warning if the driver hasn't been properly signed to be compatible with the version of Windows that's currently running on your computer.
