Congrats, good to know

if you tried with 115200, and no success, that would be necessary.

@hague said in Unreal power discharge / charge current:

I made some tests: The discharge current depends on the Screen Brightness:

idischg: 42mA @ ScreenBreath(7)
idischg: 44mA @ ScreenBreath(8)
idischg: 51mA @ ScreenBreath(9)
idischg: 58mA @ ScreenBreath(10)
idischg: 65mA @ ScreenBreath(11)
idischg: 75mA @ ScreenBreath(12)
idischg: 90mA @ ScreenBreath(13)
idischg: 105mA @ ScreenBreath(14)
idischg: 116mA @ ScreenBreath(15)

The charge current depends on the temperature:

icharge: 86mA @ 31°C
icharge: 86mA @ 44°C
icharge: 8mA @ 46°C
icharge: 8mA @ 48°C
icharge: 8mA @ 52°C

A bright screen is heating up the Stick quite fast.

Hope that helps...

is that 86mA or 8.6mA as thats quite a jump?

BTW thanks for taking the time to do all this testing.

@wikistik said in M5StickC hardware accessory notes:

I will be using the "stick" in teaching environments over the next year so I have started compiling notes on how well it works with various hardware add-ons. At the moment I have a starter list posted at: http://tinkerfarm.net/projects/the-m5stickc/m5stickc-hardware-accessories/.
I will be adding to that page as I get deeper into it, next up will be some of the commodity sensors that people use with Arduinos, since my site is aimed at beginners. I hope this might be helpful to some of the people on this forum.

Nice work. I have the first three hats and waiting on the next set of hats but not had time to test them. I have been able to UIFlow to work with the temp/pressure and humidity part of the env sensor but I have had to put on hold testing will I go back to writing up and test all my old stuff first.
You can see my work in progress nots for UIFlow in the project forum.

@cepics said in Battery level:

does it should work on GRAY M5Stick too ?

tnks

I don't think so but i could be mistaken.

@grelm I think (but i could be wrong) 10mA should be ok.

@ricardocosta
void AXP192::SetSleep(void){

Wire1.beginTransmission(0x34); Wire1.write(0x31); Wire1.endTransmission(); Wire1.requestFrom(0x34, 1); uint8_t buf = Wire1.read(); buf = (1<<3)|buf; Wire1.beginTransmission(0x34); Wire1.write(0x31); Wire1.write(buf); Wire1.endTransmission(); Wire1.beginTransmission(0x34); Wire1.write(0x12); Wire1.write(0x41); Wire1.endTransmission();

Hi

Just trying to upload script to stick via usb (IDE).
Either on mac or windows I can see stick usbslabtouart for erasing and firmware burn but it is not available to Ui Flow IDE to download the script. Core and Stick C work both well with Ui Flow IDE since they have usb option in their menu. No luck so far with Stick non-C

@ajb2k3 Thanks!

@auct

Try this...

Thank you, I saw it. How to write it in Python?

Sorry about that. I didn’t see that you were looking for a Python example. After a bit more digging, I noticed the M5Go default program has a Preview Microphone function. Check our lines 154-194 from here:

Also mine now up and running !
thanks to M5 stack support

hope it will remain stable

The problem is down to the server host, every so often the server has a fit and brakes things.

@arzaman Just upload an arduino program in the normal way. It will overwrite the UIFlow bootloader and you can continue to use the devices.

@cepics said in [Solved]M5Stick and VL53L1X:

/* This example shows how to take simple range measurements with the VL53L1X. The range readings are in units of mm. */ #include <Wire.h> #include <VL53L1X.h> VL53L1X sensor; void setup() { Serial.begin(115200); //Wire.begin(); Wire.begin(25, 13); // (SDA, SCL) grove stick //Wire.begin(21, 22); // (SDA, SCL) grove stack Wire.setClock(400000); // use 400 kHz I2C sensor.setTimeout(500); if (!sensor.init()) { Serial.println("Failed to detect and initialize sensor!"); while (1); } // Use long distance mode and allow up to 50000 us (50 ms) for a measurement. // You can change these settings to adjust the performance of the sensor, but // the minimum timing budget is 20 ms for short distance mode and 33 ms for // medium and long distance modes. See the VL53L1X datasheet for more // information on range and timing limits. sensor.setDistanceMode(VL53L1X::Long); sensor.setMeasurementTimingBudget(50000); // Start continuous readings at a rate of one measurement every 50 ms (the // inter-measurement period). This period should be at least as long as the // timing budget. sensor.startContinuous(50); } void loop() { //Serial.print(sensor.read()); //MM Serial.print(sensor.read()/10); //CM if (sensor.timeoutOccurred()) { Serial.print(" TIMEOUT"); } Serial.println(); }

it works!!!

Glad it works and sorry for posting the pins the wrong way around.

@watson said in M5Stick FRIED:

@ajb2k3 Looks like Voltage regulator chip - 5v to 3.3v

Triode is smaller than it.

Thanks @watson

@smrtokvitek just use some 3V3 regulator to step down the voltage from M5Stick and connect data lines directly. As you said, the data pins all connect directly to esp32.

@mocm You can talk with eggfly by github.
