Which is GPIO for Raspberry I2C slave?

Which is GPIO for Raspberry I2C slave?

But after read some related questions about pigpio, for the Raspberry I2C i use GPIO18 and GPIO19 (but without any resistors) and it’s work. I receive always only 16 bytes (“Hello from ESP82” with sometimes another line with “66”) of the datas “Hello from ESP8266” when it will work well but also some datas garbages.

Can you use an ESP8266 as a I2C slave?

It also is going to be hit by IRQ disable windows when doing WiFi operations, increasing the required clock cycle for stable operation. Something that short-circuits the OS IRQ handling and does the slave FSM immediately, with minimal register usage, and which makes the IRQs NMI if possible, might be able to move the needle.

Can a WEMOS di mini be an ESP32 slave?

I’m testing esp8266 (wemos DI mini) as slave with esp32 (micropython) as master, as far I can tell, esp8266 receive from ESP32 but cannot sent any data back. Micropython error is: execute without problem and my debug on esp8266 slave reports all correctly: my ESP32 communicate with attiny without any problems.

What kind of GPIO is used in Raspberry 3?

For reference GPIO 2/3 have 1k8 external pulls to 3V3. My first question is , GPIO18/GPIO19 are only used for RPi i2c SLAVE mode and SCL/SDA (GPIO2/GPIO3) are used for RPi i2c MASTER mode ?

How does invert serial logic work in pigpio?

Any read I2C data is concatenated in the returned bytearray. Invert serial logic. Returns data from the bit bang serial cyclic buffer. The returned value is a tuple of the number of bytes read and a bytearray containing the bytes. If there was an error the number of bytes read will be less than zero (and will contain the error code).

What does pigpio do on the Raspberry Pi?

pigpio is a Python module for the Raspberry which talks to the pigpio daemon to allow control of the general purpose input outputs (GPIO).
