sufyank123 0 Posted August 23, 2019 Share Posted August 23, 2019 I am using MSP432P401R and wanted to increase the I2C frequency from 100kHz(Standard) to 400kHz(Fast). In the Wire library for arduino, there is a function Wire.setclock(). Has anybody written such a function for energia? Because it is not there in energia. I went through the wire and twi libraries and found the following, In wire library, Wire.endTransmission calls a fucntion in twi library, twi_writeTo() which has the following line of code, UCBzCTL1 |= UCSSEL_2; // SMCLK Is this the line of code that sets the clock speed? Also in the twi.h library, the line of code, #define TWI_FREQ 100000L defines the frequency as 100kHz, but even if I changed it to 400000L, I don't see any change on hardware. Is this the right way? I'd appreciate if anyone can help me with this. Thanks Quote Link to post Share on other sites
