IP5306 automatic standby

JJ

Hi Ji,

Thanks for the update. Nice project. I will keep an eye on the projects section....

It seems likely the M5Stack guys would want to sort this out given that low power is one of the attractions of the ESP32, so most likely they are still working on it.

From their comment and perhaps your experience also, it may be that availability of the IP5306_I2C was the problem.

Perhaps they could use the IP5108 in future (?).

According to the data sheet (in Chinese language only by the way),
if the load current drops below 45mA during 32 seconds, the IP5306 goes into standby.

This is useful information for making some sort of heartbeat circuit to keep the IP5306 from going into standby.

Hi,

Any ideas to avoid automatic standby?
i am working with deepsleep and it wont wakeup above 30seconds setup.

Thanks!!!

Are 2018 models came with the same IP5306 stand by setup?

Could it be customized for big orders?

Thanks guys

2018 models have the same problem with IP5306 standby.

You can't get very low power consumption in deepsleep with M5Stack anyway, so waking up every 30 seconds, checking the elapsed time and going to deepsleep immediately if needed won't make much difference.

hi there, i had ordered 4k pcs ip5306_i2C, and change the newest board for this, so the new model can close this function.

@m5stack - very good news!

P.S. please also check the quality of connectors, especially female (on master board),
maybe only my m5stack has such a problem but from the beginning of use, various pins have a contact problem
with bottom plates(I check different: ioExtension/proto board/battery board).
Evidently male pins from bottom plates do not have good contact with female connector on base plate, I do not check all contacts but have problem with accu pin, adc35 pin, adc36 pin.
it's very annoying and spoils the positive impression from the module
when you can not read the input status and wonder what is wrong in the code
and it's not the fault of the code but the lack of contact

P.S.P.S please also vote for this PR: https://github.com/espressif/arduino-esp32/pull/1242
because current version of board.txt do not include proper pins_arduino.h variant for m5stack and for e.g. ADC1 or ADC2 are unknown when compile

Great news, but make shure that the new board is degned in a way that the total power consumption of all the additional circuitry (except ESP32 itself) can be reduced to at least <100 uA, otherwise it wont be very useful.

@JiKuch , @loboris, @m5stack, @JimiT

Does anyone have a list of all I2C registers of IP5306_I2C (preferably, in english)?
Also, what is the I2C address of this chip? I tried running I2C scanner and I get:

  0x68 => MPU9250
  0x0E => MAG3110
  0x75 => IP5306 ???

Correct me if I'm wrong.

Who is interested in the IP5108 solution, so look at the implementation in the section PROJECTS:
M5 Power Bank with IP5108

Same thing for IP5209 IP5109 IP5207 IP5108

@vshymanskyy Did you scann old chip (IP5306) or new version (IP5306_I2C). Can it be possible, that old version can I2C too?

@vshymanskyy please, could you send schematic of IP56306 I2C connection? I try to connect to my (which should have I2C) - but she doesn't reply. I use external microcontroller with external supply. Also I connect SCL to 2nd and SDA to 3st pin pin of IP5306. IP5306 powered from li-ion battery.
