AXP192 Support on T22_V1.0 #1

Closed gampam2000 closed 4 years ago

Hi,

i got it running on the TTGO T-Beam T22_V1.0 but i need to enable all the powers to get the GPS Module working. If i only enable

a.enablePower(axp202.AXP192_LDO3) #LDO3 = GPS

it does not work, why?

This is written for AXP202. It was not tested on 192. Some of them are wrong. I didn't have time to update it, but it is OK to turn on the power. You can use the voltmeter to measure whether the GPS power pin has voltage.

i got the GPS running, but if I operate it on battery i can not shut it of, it seem that the PWR button is connected to the APX192 and i have no clue how to configure it. Any suggestions?

Better support for AXP192 for the TTGO T-Beam T22_V1.0 would be really great, i hope you can find some time.

The PWR button only controls the AXP192 switch. If you don't want to use GPS, you can turn off the gps channel power.

a.disablePower(axp202.AXP192_LDO3) #LDO3 = GPS

Thanks, that works fine. But when I insert a Battery the whole Device is always on and the PWR Button does nothing. My Question was if i can configure the PWR Button (axp192 powerkey) to shut the board completely off and on? If yes how?

By default, the battery will not turn on automatically, but you need to press the PWR button for two seconds to start it. Press and hold for 6 seconds to enter the shutdown. Refer to my Arduino library for the function of configuring the PWR button
