ken 0 Posted May 27 I am trying to interface as I need up to 6 serial ports. In the case of RaspberryPi, there is a product that can use up to 32 by creating two serial ports using the SC16IS752 using I2C and adding addresses. I'm trying to apply this to Tinker Board2, but there are problems with the driver, etc. Could you please give me some reference information? Have a good day.
