UPS PIco HV 1.0 issues

Postby ktb » Wed Feb 22, 2017 7:09 am

Hi Pimaster (and Pimodules Team),

It's been a while since I've visited the forum. It's also been a while since I've used the UPS PIco (HV 1.0). I wish my post could be more positive than it is, but here goes...

I just took out the UPS PIco HV 1.0 and Raspberry Pi 2B. I hadn't updated the firmware since version 20. Attempting to perform a fresh install of the UPS PIco using the latest Simple_Setting_Guide_for_the_UPS_PIco.pdf, UPS_PIco_Manual.pdf, UPS_PIco_Supporting_Files.zip and latest UPS_PIco_Firmware_Update.zip on 2017-01-11-raspbian-jessie.img leads to some issues. Your guides are full of mistakes and poor instructions (even more than the last time I used them).

The biggest problem which you should correct for the sake of your customers has to do with updating the firmware. The instructions say to disable Serial (A8 Serial) using raspi-config before updating the firmware. This will not work. After disabling Serial using raspi-config, it is then necessary to to set enable_uart=1 in config.txt before rebooting and actually running the firmware update. This is because disabling Serial in raspi-config also sets enable_uart=0 in config.txt which will lead to a error related to being unable to find /dev/ttyAMA0 when running the firmware update script -- picofu3.py (ERROR: Serial port "/dev/ttyAMA0" cannot be found!). Setting enable_uart=1 allowed me to update to the latest officially published firmware (5c).

BTW, why is "sudo" necessary when downloading the firmware ZIP file? It's not necessary. Why tell your customers to do that? ("sudo wget http://www.pimodules.com/_zip/UPS_PIco_ ... Update.zip")

Moving on to the installation instructions, you're still recommending users do silly things like add i2c-bcm2708 and rtc-ds1307 to /etc/modules. Why? Device Tree takes care of this sort of thing. There is no reason for a user to even touch /etc/modules (at least when using Raspbian).
Code: Select all
# Uncomment this to enable the I2C interface
dtparam=i2c_arm=on

# Uncomment this to enable the UPS Pico IR receiver
dtoverlay=lirc-rpi:gpio_in_pin=18,gpio_in_pull=down

# Uncomment this to enable the UPS Pico RTC
dtoverlay=i2c-rtc,ds1307


Device Tree also makes adding echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device to /etc/rc.local completely unnecessary. Why are you still telling your customers to do that?

BTW, did you ever actually implement automatic temperature controlled fan functionality ("implemented Automatic Temperature Control PWM fan controller")? It looks like you never did. Also, did XTEA ever actually get implemented so that it is useful to your customers? It doesn't look like that was ever implemented either. Honestly, I doubt these things will ever be implemented at this point seeing as how old the UPS PIco HV 1.0 is at this point and how many of your past customers still seem to be waiting for promised functionality. At the very least you could stop publishing manuals which lead your customers to believe that these functionalities exist for the UPS PIco. I've already brought these issues to your attention in the past.

What ever happened to the planned add-on boards for the UPS PIco? It looks like that never happened either.

Good luck with your future products and business.

Sincerely,
KTB

Another issue...

What happened to pico_status.py? I thought I fixed that for you. You're distributing a version which is apparently missing my fixes. I still have the fixed code in case you lost it. Look at the temperature values:

I suppose this could be caused by the same old issue that the temperature readings come back wrong or corrupt if the UPS PIco battery is charging. EDIT: No, that doesn't appear to be the problem.

Check this out. Watch the battery voltage drop to 2.98V while it should be charging and then it apparently starts charging again at which point SOT23 temperature readings begin coming back with seemingly valid values. TO-92 is always 00, why?:

This is like a bad joke. Those readings were all taken about 5-10 seconds apart from each other in a row. Will this product ever work properly?

Note: The RPF 4.9.x kernel also breaks the UPS PIco HV 1.0 I2C functionality. I just thought I'd make a note of it since there isn't a warning about running rpi-update in this forum section. BTW, it's not just BRANCH=next rpi-update which breaks things, standard rpi-update also delivers a 4.9.x kernel now. We probably have about a month until the 4.9.x kernel makes it into regular APT upgrades.

Hi ktb,
We have been informed about the new update and checking what is going wrong. We will of course work on it and will provide a solution. We will need some time to fix it and provide a firmware update.
Warmest Regards

This is like a bad joke. Those readings were all taken about 5-10 seconds apart from each other in a row. Will this product ever work properly?


Hi ktb,
Please specify conditions you are using, with bad temp reading. Please also send the corrected by you as you claim the fixes to the pico_status script. We would be happy to include them to the release
Warmest Regards
PiM
