Expand description

I2C2 peripheral operating in master mode

Implementations§

source§

impl<SCL, SDA> I2c2<(SCL, SDA)>

source

pub fn new( i2c: I2C2, pins: (SCL, SDA), freq_hz: u32, rcc: &mut RCC, pullup: bool, cs: &CriticalSection ) -> Selfwhere SCL: I2c2Scl + PinOps, SDA: I2c2Sda + PinOps,

Configures the I2C peripheral as master with the indicated frequency. The implementation takes care of setting the peripheral to standard/fast mode depending on the indicated frequency and generates values for SCLL and SCLH durations

Panics
  • Frequency is greater than 1 MHz
  • Resulting TIMINGR fields PRESC, SCLDEL, SCADEL, SCLH, SCLL are out of range
source

pub fn free(self) -> (I2C2, (SCL, SDA))

Releases the I2C peripheral and associated pins
