Re: Upload failed XPD Version 0.4.1a

Has anyone tried the Download and Upload functionality in XPD Version 0.4.1a with a 124110ST-MII-LYEN EDITION controller ?

I've been able to Download the parameters OK but when try to upload the same values (no changes) I get :-

"Upload failed: byte must be in range(0, 256)"
It looks like the default PySerial version in pip breaks XPD at the moment (v 3.4).

Uninstall PySerial v3.4 and install version 2.5

On Linux:
pip2 uninstall --user pyserial
pip2 install --user pyserial==2.5

(Not sure how python packages are handled on windows, don't need that kind of negativity in my life, frankly. :P )

Hi people.
The other day I finished (almost finished) a small device on Arduino that allows you to program the controller in the field.
It is a little damp, but it works.
If anyone is interested, here is the link: https://github.com/Felan412/AVR_arduno_ ... ike_based-

If something is wrong with copyright, let me know I will fix it.

Thanks for your contribution, today I installed xpd, that is the 3 programs (as specified) and it worked well with window 10.
I put the defaut on the 2, 100%, and the 3 position switch on the 2.
my 2018 cable usb already had the bridge,
(EB3 12 FET cellman).
I've made some adjustments, nothing else.
The Pas now works better, it stops almost immediately.
