 # stm32f1-hal
 Because the design of [stm32f1xx-hal](https://github.com/stm32-rs/stm32f1xx-hal) is unsuitable for my needs and [stm32-hal](https://github.com/David-OConnor/stm32-hal) doesn't support the F1 series, I decided to write a new crate.
-
 Many codes come from [stm32f1xx-hal](https://github.com/stm32-rs/stm32f1xx-hal).
 
+Example is [here](https://github.com/jw-mcu-rust/stm32f1-hal/blob/main/examples/f103c8/src/main.rs).

 ## Design
 Below are the design principles.
 1. Readability is the most important.
@@ -13,3 +14,6 @@ Below are the design principles.
 Therefore, if a module is quite complex, I would not use a macro + generic approach, as it is too difficult to read.
 
 Instead, I use a script to generate code for GPIO alternate function remapping and a synchronization script to manage duplicate code across peripherals.

+## Note
+This project is still in its early stages, with only a few features completed.
