HI I found CH32X035 I2C is disabled. If uncomment it, the will pass complie(Not yet download to the bord). May I know if any bug found for CH32X035 I2C? Thanks

Some time ago another user encountered this too. I had the same with SPI on the CH32V003. That user noted I2C (master mode) works on the CH32X035 when enabled. See also issue #26 and #29 here.

Are you sure that you have won the silicon lottery? See the X035 datasheet.

HI, I also found that issue. I just call WCH, They told me for newer patch of chip will not have that issue. We should not able to buy such old patch of chip in the market

To verify this function, a corresponding version of the chip needs to be used here.
