Hi All,
I want to configure I2C3 in imxrt106s as master for interfacing a fuel gauge.Following are the configurations I have given,
lpi2c_master_config_t masterConfig;
LPI2C_MasterGetDefaultConfig(&masterConfig);
masterConfig.enableDoze = true;
masterConfig.baudRate_Hz = 100000UL;
LPI2C_MasterInit(LPI2C3_PERIPHERAL, &masterConfig, LPI2C3_CLOCK_FREQ);
Default configurations
-------------------------------
masterConfig->enableMaster = true;
masterConfig->debugEnable = false;
masterConfig->enableDoze = true;
masterConfig->ignoreAck = false;
masterConfig->pinConfig = kLPI2C_2PinOpenDrain;
masterConfig->baudRate_Hz = 100000U;
masterConfig->busIdleTimeout_ns = 0U;
masterConfig->pinLowTimeout_ns = 0U;
masterConfig->sdaGlitchFilterWidth_ns = 0U;
masterConfig->sclGlitchFilterWidth_ns = 0U;
masterConfig->hostRequest.enable = false;
masterConfig->hostRequest.source = kLPI2C_HostRequestExternalPin;
masterConfig->hostRequest.polarity = kLPI2C_HostRequestPinActiveHigh;
After the initialisation I tried to read register values of fuel guage.But no activity is happening on I2C3. Always I2C3 SCL and SDA is held as high.Do we need to change any configurations?
