I am using an SC18IM700IP to control an I2C slave device.
When I power up the circuit, the SC18IM700 return the two bytes 0x4F and 0x4B; ‘OK’ in ASCII.
When I send the "IP" command, the result can be seen in the picture attached.
If I write a number in any of the registers, then I read the same number for all of the registers.
Here you have my schematic:
Q500 is not installed
SDA and SCL have 10kOhm pull-up resistors.
Any help will be appreciated
