Hi,

Please provide me your Raspberry Pi Model you are using as also OS running on it.

Cam you also send me the full window of messages you are receiving, I mean messages without your modification

Thank you and Kind Regards

Hi,

I made an image copy 16GB, updated and upgraded with everything installed. Please try this. The link to it is provided in the text file you can downloads form here:

https://pimodules.com/download/61/public/3365/image_12_05_2022_link.txt

User:pi

Password:1

Just download this *.txt file, use provided in it link, to download the SD card image, unzip, and then use provided in the zip file imager program to burn the SD card.

Please keep me informed.

BR Pi Master

[EDIT]

Please do not use *.hex file I left inside of the SD card image. It is my own testing hex file. Please use the official file we released

Hi, A new version of manual and firmware is already ready. However we delay little bit the release for  few days, as doing extensive testing. We will update the manual with requested information also.

Hi, I am a new Italian user. I bougth a UPS Pico HV4 board stack with a lot of adv extensions. At last I got mounted everything, done every software updating and tailoring, and then i wanted to apply the new firmware, but... in the attached screenshot the stuck situation.

The Os is Raspberry OS 64 bullseye on ssd

A word from you in a private email started a bell "if you have activated serial port", but non mentioned in the setup flow.

I read more carefully the whole manual and found the the register settings to activate the serial port, so I launched the commands:

$ sudo i2cset -y 1 0x6b 0x02 0x03  for pi

$ sudo i2cset -y 1 0x6b 0x02 0x30  for UPS

is it right?

then I tried again:

pi@raspups:~ $ sudo python UPS_PIco_HV4_BL.py -l -f ups_pico4_main_Firmware_012A_10052022.hex

Sorry, forgot python version: 3.9.2

@eighty2fifty1 

Hi, 

Yes, you are right. It was a bug. Corrected now. Please download the latest version of the firmware, we corrected this bug as also added many new features.

BR Pi Master

@andycianci 

OK

@xani 

Hi, 

Yes it is JST connector 2.5mm.

BR Pi Master

@andycianci 

Hi 

I check it and answer on Monday.

However we already wrote a new handler for the serial Port(s) so rather release them also on Monday. Better to wait for this newer firmware and then test them

BR Pi Master

@andycianci 

please run it  again, newer version. I will ask Vit about this possible bug. Many thanks to Vit for this perfect piece of software done is Pythin3

BR Pi Master

At last I had time to spend testing the new FW.

No result.

These are the steps I followed:

and what?

@piadmin 

I left a post some time ago yet waiting for moderation...

It seems there is something wrong in serial communication between pi and pico; please, look at my post where I reported the trace of actions.

@andycianci 

Sorry receiving so many porn email, so missed you. Check it and answer today later on
