CRC16 for STM32F030

[Yq_it]

I am trying to use the hardware peripheral on the STM32F030 to calculate a 16-bit CRC for a modbus RTU application. But I don't know how to do it.

Was from old SPL, but should be portable

I need  STM32F030 config for CRC16. I try config register for CRC ，but I can not getting the right results

The F030 doesn't support the programmable modes, use the software examples.
