Let’s understand different types of errors that may occur during I2C communication. 1. Bus error: This error happens when the interface detects an SDA’s rising or falling edge while SCL is high, occurring in a non-valid position during a byte transfer. During the byte transfer, if any invalid ...
Why HAL_I2C_Master_Transmit always returns HAL_BUSY?
WebInter-Integrated Circuit (I2C) is a communication bus protocol developed by Philips Semiconductor (now NXP Semiconductors) in 1982. It is a relatively slow protocol but has seen widespread use due to its simplicity and robustness. Most microcontrollers have at least 1 I2C peripheral controller built in to the silicon.
