Cannot find I2C devices on ESP32

... to make a display (128x32 I2C Pi OLED) to work with esp32 (ESP - WROOM-32) OLED device is working properly as I have tested it with Arduino using Adafruit's libraries. Esp32 device is working properly as it runs other code without problem. I followed a video [https://www.youtube.com/watch?v=qqxgKZCTdUk] ...

uasyncio and display

Hi, I tried to use pms5003 wich give air quality data and need the uasyncio module. I would like display data on a epaper. I tried to add epaper code in the pms module in a simple definition (line 59) that I call in the def(print) of pms module (line 449). But after 2 rights cycles, nothing happen. ...

Re: Anyone working on MCP4728 (12-Bit, Quad Digital-to-Analog Converter with EEPROM Memory) driver?

Hi friends, Is there anyone working on establishing MCP4728 (12-Bit, Quad Digital-to-Analog Converter with EEPROM Memory) driver? I am recently working on DAC expander for my device. I found the driver for MCP4725 which has only a single channel. Now I wish to have more channels, so I found MCP4728...

Re: bme680 adafruit on pyboard

... I have tested until now with the bme680 from seeed... Until now, I have never seen difference between the bme680 from seed and the bme680 from adafruit. But Now, I have tested, and the g.gas works with the bme680 from adafruit... Others values are the same. The bme.altitude works too. Thanks ...

Re: bme680 adafruit on pyboard

Nice. Thanks Roberthh for this perfect job. There is only one difference in the bme.gaz value construction between this lib and the adafruit-lib... In the adafruit : "self._last_reading = time.monotonic()" In this lib : "self._last_reading = time.ticks_ms()" The value of bme.gas stay the ...

Re: bme680 adafruit on pyboard

Github was broken yesterday afternoon. Now it seems to work again. The humidity sensor of the BME680 seems a little bit off. I made once a test series with various sensors in controlled humidity environments (Box with saturated solutions of various chemicals).The results are below. Green=within spec...

Re: bme680 adafruit on pyboard

Goood. github's references have stranges behaviours on the net...with my system too? For me, the humidity value is upper of 10 with reality. It's easy to correct it. Temperature and pressure are goods. I have tried the bme.gas value... always the same result : 2938733 ... Calcul of bme.gas is comple...
