Version T22 V1.0: LED Built-in GPIO

[rcomellas]

I have tested the blink sketch from the examples folder in the new version T22 V1.0 but it doesn't work with GPIO14.
Anyone has the right IO?

I do not believe the board has a built-in LED other than the charging LED. However, you can control this!

Have a look at the AXP202X Library by Lewis He:
https://platformio.org/lib/show/6657/AXP202X_Library

Add the following to your sketch:
#include <axp20x.h> AXP20X_Class axp;
And in Setup():
`
//Turn everything on
axp.setPowerOutPut(AXP192_LDO2, AXP202_ON);
axp.setPowerOutPut(AXP192_LDO3, AXP202_ON);
axp.setPowerOutPut(AXP192_DCDC1, AXP202_ON);
axp.setPowerOutPut(AXP192_DCDC2, AXP202_ON);
axp.setPowerOutPut(AXP192_DCDC3, AXP202_ON);
axp.setPowerOutPut(AXP192_EXTEN, AXP202_ON);
axp.setDCDC1Voltage(3300); //Set Pin header 3.3V line to 3.3V. Processor is happy down to 1.8V which saves power

//I don't think this board has a built in LED, other than the Charge LED, controlled by this:
// AXP20X_LED_OFF,
// AXP20X_LED_BLINK_1HZ,
// AXP20X_LED_BLINK_4HZ,
// AXP20X_LED_LOW_LEVEL,

axp.setChgLEDMode(AXP20X_LED_OFF);
