@world101 So I figured it out:

On that particular module I connected it as follows:

Left pin on module labeled 'S' to 5v on the righthand side of M5Stack (red wire)
Center pin on module (not labeled) to GND on the righthand side of M5Stack (yellow wire)
Right pin on module labeled '--' to pin 2 on the righthand side of the M5Stack (orange wire)
After you compile and upload the app tap the module to see the "Tap" message.

Hi !

Thanks for this, it was very usefull to me for handling my brand new M5 CoreInk :)

It should definitely be in the Github examples from M5.

@calin I know it’s an old topic (!) but where could I find the Arduino ide code for the Weather Station?

Hope you can help 😊

@fonix232 Thanks! For me the exercise is much more exploring how the epaper display works when drawing the different components and how to optimize partial updates.

I will have a look at the projects you mentioned and see if I can find some inspiration!

Make an improvement in the main call routine. The return value of getBME280 is a boolean.
now it is possible to check whether a BME280 is connected correctly.

bool getBME280(TwoWire *theWire, double *t, double *p, double *h) { _i2c = theWire; /* check of BME280 is avilable */ uint8_t value = read8(0xD0); if (value == 0x60) // BME280 detected { reset_BME280(); // Reset BME280 write8(BME280_REGISTER_CONTROLHUMID,(uint8_t)0x01); // Select control humidity register write8(BME280_REGISTER_CONTROL, (uint8_t)0x27); // Select control measurement register write8(BME280_REGISTER_CONFIG, (uint8_t)0xA0); // Select config register readCoefficients(); // Read coefficients from BME280 *t = get_Temperature(); // Get temperature *p = get_Pressure()/100.0; // Get pressure *h = get_Humidity(); // Get Humidity return true; } else { return false; // No BME280 detected } }

Cheers,

Jan

did you find any micropython code any bluetooth communication for arduino. with arduino c code communication is not hard.i made reader https://i.ibb.co/tLJyWht/mireader.png
it is reads actual values and creates array for histogram.half part of the screen show histograms graph
alt metni
i used nRF Connect app on android which bt id and details will be used on the code.

Manually as I haven't worked out the server side of things.
I hit a ram issue on the coreink preventing me pulling it from online so I need to work out how to make a server to do the lifting and parsing.

Hello @calmasacow

I get the impression you are trying to do to many things at once. May I suggest you start slow and take it step by step?

first make sure you can upload a program from your computer successfully and multiple times start with a simple program like this then try to modify it, for instance by changing the text

Only if above steps work reliably it makes sense to continue with your own stuff.

Good luck!
Felix

I'm trying to push for a unified API but the problem is that some of the devices are slightly different and require slightly different commands.
Please add your request for a unified API to the suggestions list.

Hello @LasNiko

nice project!

You can use three backticks before and after the code. Full description here.

Thanks
Felix

Hi Guys,

ihm new with M5Stack. I have a MCore2 and try compile this in visual code with plattform.io.

How i must use the code in Plattform.io ? If i compile the code, the device showing black screen.

Can anyone help me ?
