 ## Supported Devices and Peripherals
 
 Currently, supported chips are listed in `Cargo.toml` as feature flags.
 
-Supported chip flags: `py32f030f16`, `py32f030k28`, More is coming...

 others should work if you are careful as most peripherals are similar enough.In fact, the IPs of peripherals in different PY32 series may be consistent. Moreover, some series use the same die, so it might not require much work.
