Configure SuperCap on HV4.0

funkyteilchen · 2024-11-26T15:55:53Z

Hey dear pimodule Team, I set up UPS PIco HV4.0B/C like described in the manual. I had some trouble getting the current firmware on the UPS, the serial communication could not be established, I managed then to upload the current firmware 179 with invoking the manual bootloader mode at the point in the firmware uploader skript, where the loop around trying to communicate over serial with the ups happens. I would like to use the UPS now with only a supercap and no secondary battery. I do not have the pogo pins installed and would like to not use them if possible. I set per i2c sudo i2cset -y 1 0x6b 0x07 0x43 like it says in the manual (Selects power source the 100F Supercapacitor as the ONLY Power Backup source - (Single Mode)). However, when I run the pico_status skript I get: ************************************************* UPS PIco HV4.0 Status Version 1.4 Relase Date 13.03.2024 Compatible with Firmware 0x0168 and up ************************************************* System Clock read from Date................: 2024-11-26 15:42:10 System Clock read from HWCLOCK.............: 2024-11-26 15:42:09.971614+01:00 UPS PIco RTC Registers direct read.........: 2024-11-26 14:42:11 UPS PIco Firmware..........................: 0179 UPS PIco Bootloader........................: 41 UPS PIco PCB Version.......................: 42 UPS PIco PCB Default Battery...............: Battery LiPO 'L' 0x4C UPS PIco Set Battery.......................: On Board Super Cap (100F) 'C' 0x43 Raspberry Pi Core Temprature...............: 43 C Raspberry Pi Core Temprature read by PICo..: 44 C Embedded Fan Temp.

The running time on battery is set to the default value of 1 min. The raspberry is powered with USB (official power device 5V@5A), fan is working, rtc is working.The Daemon is running and the light SYS is blinking at around 700ms and the SCA led is on permanently. So the supercap is fully loaded now and I unplug the USB power, what happens than is that the raspberry dies off quite quickly and I think it does not regulary shutdown. I commented out the "sudo shutdown now -h" commands in the daemon and the raspberry stops nevertheless. However, the green activity led keeps on blinking and the supercap seem to be discharging as the correspondin led turns off. The green led of the raspberry blinks and the sys led from the UPS stays on until the the supercap is discharged (which takes longer than 1 min like I would think the battery timer should shutwdon the UPS?). Could you maybe give me a hint, if there is any other setting I can make or I misunderstood something?
