When you do, you can add the Extended ICU driver I wrote for 3.0.0.
It can be found here: https://github.com/korken89/KFly_ChibiO ... er/drivers

Hey,

I made the changes for 3.0 and renamed the files/defines to avoid conflicts.
They use "DRIVER_USE_*" instead of "HAL_USE_*" now. The API is unchanged.

I added a dacConvertOne() function to the DAC driver, useful in case you only need a simple conversion or want to use the timers/dma for something else.

I added the eicu driver.
