When I trying to use iic in ch32v003, the arduino library may cost a lot of memory to initialize the iic (about 7000bytes),which is almost the half of the tatal ROM.Frankly speaking ,this way can success initalizing.When I trying to cut down the rom usage by replace the arduino framework with None-os,but it can't work correctly.Neither the offical (WCH.)'s example code nor my custom code did not work in it.But,when I paste them to the MonuRiver Studio,it can work normally.
