I2C is a communication bus designed by Philips, for chips to communicate with each other on a PCB. It is commonly used, however, for connecting sensors, such as the two examples later in this instructable and port expanders, because you can have multiple devices on the same two pins. 步骤...

Re: PIO: How to get acknowledge bit from my I2C device Tue Jun 06, 2023 10:32 am A bit more reading of the Micropython docs says that you want: Code:Select all @asm_pio(set_pins=(PIO.IN_HIGH) ... to get the PINDIRS initialised correctly, but you will still need one sm.exec(...
I am working on a gas flow sensor SFM4100It's communcation protocol is i2c. And according to gasses bus adresses are changing. For o2 gas, i2c address is 0x02.When I connected the all pins according to datasheet , raspberry pi doesn't detect i2c address. I tried both Code: Select ...
