Datasheet/manual usually specify the I2C address. You can find the the I2C address on datasheet/manual. However, there is a faster way, use I2C Scanner by doing the following step: Connect I2C sensor/device to
I notice that the configBlock gets written to the chip every time you want to take a measurement (in the function startMeasurement). The configBlock's first byte is the device address. Is there a nice way to change the device's address t...
Description: The TCA9548A I2C Multiplexer Module is to enable to connect devices with the same I2C address (up to 8 same address I2C) hooked up to one microcontroller. The multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pin with your command. The multiple...
adc0 = Pin(Pin.A0, Pin.ANALOG) #Initializing the temperature reading pin to A0. lcd = LCD1602_I2C(i2c_addr=0x20)#Initializing the I2C address for the LCD display. lcd.backlight(True) #Turn on the backlight lcd.clear()#Clear the screen lcd.set_cursor(2,0)#Set the cursor position ...
i2c_master_write_to_device(i2c_port_t i2c_num,uint8_t device_address,const uint8_t*write_buffer,size_t write_size,TickType_t ticks_to_wait) As the name suggests, thei2c_master_write_to_deviceis used to write the data to the device. It’s parameters are : ...
Learn how to use I2C to configure and read temperature and humidity from the HDC2010 with the Arduino See a demo of the HDC2010 and the LCD display See a step-by-step guide through the code so you can reproduce these results with the HDC2010 on your own ...
this 0x3c is the i2c address for your OLED display. Now if you use multiple i2c devices your i2c address would be different, you can use I2C scanner code and find the i2c address of your device. Next we will clear display using display.clearDisplay(); command. ...
In this tutorial we will learn how the I2C communication protocol works, as well as, make a practical example of Arduino I2C communication with...
and there find the section: I2C and enable: i2c0 / system restart then proceed as you previously provided on the forum. How to connect LCD to your model ... probably like I did to myOPi3-LTSaccording to this tutorial. Of course the board is different but you have ...
