I use stm32373c_eval board and I try to acquire and send test data by i2c communication.The max speed of usb-i2c i use is 400k and board i2c clock frequency is 72M.I downloaded the I2C_Timing_Configuration_V1.0.1.xls from st website.I try to configur...

Thanks for all your reply. I am a beginner. Can you just kindly give me a number i can use for the i2c timing setting? or give me the best number of Rise time and Fall time?BTW, the speed of usb-i2c i use is 400k and the evaluation board i2c clock f...

Tesla, Thank you for your reply! Actually in the project, I create a global data array and put the array in the loop. During the loop, the data array will be updated every time after acquired a new value. I also add a timer to save the data every 1...
