Dec 19, 2004 · Dec 13, 2004. #4. Typical I2C bus can work upto a few centimeters only, with a throughput of 100kbps on standard I2C and 400kbps on Fast I2C. Philips has one application note which shows how to extend I2C bus upto one mile long. App. note details are: AN452. One mile long I2C communication using the P82B715.
The Raspberry Pi RP2040 is a high performance, dual-core, 32-bit microcontroller. One of the more versatile subsystems are the Programmable I/O (PIO) blocks, instruction driven machines with predictable, cycle-precise timing. The Raspberry-provided examples demonstrate how to implement a number of bus interfaces, including SPI and I2C.

1 1. Without more information it's hard to tell. Might be electrical properties are not okay for chosen frequency, might be frequency itself is not correct for all devices (hint: start from 100kHz for all). Might be driver issue, or simple your code is not correct (read datasheet). – 0andriy.
Oct 18, 2018 · There are two groups of devices at play. One group works on data, but may need information to be stored or recalled from external sources. This is the master.
Oct 2, 2019 · This simply creates an I2C bus. TwoWire I2CBME = TwoWire(0); In the setup (), initialize the I2C communication with the pins you’ve defined earlier. The third parameter is the clock frequency. I2CBME.begin(I2C_SDA, I2C_SCL, 400000); Finally, initialize a BME280 object with your sensor address and your TwoWire object.
