hi, i am beginner at the atmel mcu and now i am developing a little device with a samd51 based custom board.
my board has a security chip and interfaces with it through I2C. so i configurated the SAMD51G18 as I2C master.
i tested i2c1 (SERCOM4) with i2c example function but i could not see any clock or data signal from the i2c pins
here are the schematic
i assigned gclk0 to the mcu, uart and two i2c.
now i am testing with the code which atmel start generated.
here is clock, pin initialization code
and here is main
struct io_descriptor *I2C_1_io;
/* Replace with your application code */
first, uart, i2c0 works properly. but when i checked the PA12 pin of the I2C_1 clock with my oscilloscope , i could not find any signal yet.
i want to know what i missed ?? is it clock problem or something else ??
previously thanks :-(
