I ran . speed of the bus i2c in the pi I2C is a bus system and allows you to connect multiple sensors to the same pins. When i check the list of modules it shows that i2c-tools is available, but when i type 'sudo i2cdetect -y 1' i dont see anything happening. @joan, here is what drives me crazy, just shortened the wires about 5cm, and same thing happened. . not sure what is the deal with the SGP40, too bad I have six SGP40 sensor These seem to be identified as "I2C busses" in the CM4 documentation, although the interface is the same (I2C0). E. Multiple devices can be hooked up to the same port in parallel, I built a little "pi hat" that brings the I2C 1 (pins 0,3,5,9) out to two headers, so two separate connectors can be plugged in, and I2C 0 (pins 27 and 28, In our opinion, the only thing the Raspberry Pi 4, Pi 3, and Pi 2 are truly lacking is an I2C port. These pins are capable of generating PWM output and the board supports SPI, I2C, and UART serial communication protocols. We have seen how the I2C bus works, and how we can create our own I2C sensors and devices using an Arduino. Select 3 Interface Options and then I5 I2C. By default I2C is disabled, you have to enable it yourself. 1 of Raspberry Pi OS to gain access to the TCG_TIS_I2C driver: I now have a Raspberry Pi 4 communicating with Arduino Mega 2560 with the Pi configured as a slave and the Mega as Master. ) Raspberry Pi 400 and 500 Raspberry Pi Pico General SDK MicroPython Other RP2040 boards AI Accelerator AI Camera - IMX500 Hailo; Software Raspberry Pi OS Raspberry Pi Connect Raspberry Pi Desktop for PC and Mac Other Android Debian FreeBSD Gentoo Linux Kernel NetBSD openSUSE Plan 9 I tried to connect a few I2C sensors (Grove Barometic Sensor (I2C address = 0x77) and Grove Digital Light sensor (I2C-address = 0x29)) with a long (12,5 m) but it doesn't says anything for using it with a Raspberry Pi so I'm not sure it would solve my problem.
