Re: I2C for Multiple Clients Modification - XCORE 200 MC

For the default setting, I found i2c_share is used in the usb audio firmware, why is it needed? as the compiler will complain and avoid multi use of i2c in different thread, swlock seems useless, it will also hunt performance unnecessary.

Re: I2C for Multiple Clients Modification - XCORE 200 MC

Does anybody know how many MIPS if it is changed to use lib_I2C run in main par, any MIPS different during i2c client active and idle? anyway to ensure it will not affect the other thread?
