Hi,
There is so much in UIFlow. It would be helpfull to have a load of DIY examples. How To use I2C for a <non> M5stack unit sensor. And so on.
The M5stack demo's are not very usefull in this.
I'm having a hard time to find examples how to use advanced blockly's
Any suggestions?
Regards,
Edwin

FYI; light sleep current pulled out of the battery depend on the battery voltage:
<2.7V device wont wake up anymore
2.7V 4.4mA
3.0V 3.9mA
3.7V 3.1mA
4.2V 2.7mA
This dependacy is caused by the DC-DC conversion that converts the Lipo voltage first to 5Vdc. (SY7088 chip).
The 5Vdc gets also down converted to 3v3 (SY8089 chip) .
According to the datasheet, the ESP itself should only use 0.8mA in light sleep. So 2mA gets waisted.
What a pitty.

The above is not completely true. I'm using the M5GFX lib and when I execute the function display.sleep(); before going to deep sleep (esp_deep_sleep_start();) the sleep current drops to a 1.25mA. Still considerable...
You need also to set the POWER_HOLD_PIN to '1' once. So in your setup:
digitalWrite(POWER_HOLD_PIN,1); //needed to put the state to 1
gpio_hold_en(GPIO_NUM_12); //needed apparantly to keep the output also in light sleep WTF?
I'm now busy doing the SHT30 with I2C.
If I may pick you brain a little more.
The label blockly seems to choose itself how to show the data.
Decimal, binairy, text. I want it to show a list (or sub-item) only binary. Now it's mixed.
Have been seaching now for an hour or so. Can't find it how.
Do you know how?
Thanks ajb2k3. I'm not sure why it should be your 'fault'. Anyway thanx for sharing the interesting information you've put together.
What i'm really looking for is an example where they use a unit totally with the basic/advanced blockly's.
So without adding it as a unit, but purely creating the I2C.
I'm going to try myself, but it would speed up things so much if available.
