thanks for the help @felmue - ive got it working now - i think i must have been pretty tired because I have no idea how all 3 attempts failed. It works with .waspressed and by attaching a handler to events for the M5.BtnA - I have no idea what I was doing wrong all 3 times. I found one issue - it was a silly mistake in my handler logic :D but this does not explain .ispressed not working before. Maybe its something to do with a lack of sensitiviity as well - but the important thing is - they do work and I've got it working. But trying to make a button bigger all the way down to 280 does not seem to work - which is a shame becasue I have to make 2 declarations to the handler. but thats ok. Thank you

Thanks for your information and link @felmue My initial idea was to buy two TTGO LoRa32 but I preferred these two cores because I saw that they had Lora modules. For the moment I'm going back to the NodeMCU that I find much more comfortable and in a few months I will look at the M5Stack again. Thank you for your time Carles

If your on mac the downloaded firmwares can be found by right clicking M5Burner selecting "Show Package contents" then clicking through to Contents > Resources > Packages > fw then you will find the firmware files in each respective core folders. I don't have a linux machine handy at the moment but perhaps the folder structure is similar

Thanks, I will also have a look at Thonny.

@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!

Thanks again @world101 I have seen it. But I think it would have to be in the model documentation, if it is I missed it. Have a nice day Carles

@romeokienzler said in How to flash tasmona or anything to M5Stack ATOM Lite using esptool?: after hard_r^Cet Just to point out a possible issue, it looks I like you have a Control-C in your command by mistake. Is that a copy/paste error?

good points ! replace the (useless) temp/humidity sensor with a speaker/piezo to create a form of tactile feedback for the touchscreen ('click') or a general 'bleep' . a led indicator when device is on (switchable)

Adding investigation, this seems to happen only if you upload to the core2 an empty project.

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

Thank you for this. I was looking for this! Cheers, Jan
