hello
I am trying to communicate STM32F100C8T6B micro controller with MMA8653 Accelerometer using I2C
I sent the start condition and the adrress in correct way and I traced it using scope
the address is 0x3A but no ACK received from the Accelerometer.
this is the image of the Data and clock but no ACK
and also I tried to use I2C bit banging but the rising time and falling time of the port pin is 20 micro_second which exceed the max time in datasheet
and this is the waveform and how can I make the rise time and fall time max 300 nanosecond
thanks in advance
