HELLO,the mcu i use is stm32g070cbt,my ch101 can successfully download fw into flash,but when i change the i2c address to application i2c address, and execute the function ch_common_prepare_pulse_timer,i get a NACK from ch101.the attached pic shows that when i send the i2c address and register address, i get ack.But when i send the num_bytes,the sda is very strange,and after that ch101 reply NACK.Anyone know the problem?thx
I assume the first line is your I2C SCL clock , the clock sequency looks very strange, not have full clocks for each cycle.
