Struct stm32_hal2::crc::Config [−][src]
pub struct Config { /* fields omitted */ }
Expand description
CRC unit configuration.
Implementations
Creates the Config struct with the default configuration of the STM32H7 CRC unit:
0x04C1_1DB7
polynomial0xFFFF_FFFF
initial value- Bits not reflected
0
output XOR
This configuration is the MPEG-2 CRC.
Set the polynomial.
Set the initial value of the CRC. The CRC unit will only use the needed
bits to match the polynomial; the default initial value 0xFFFF_FFFF
will actually write 0x7F
in the case of a 7-bit CRC, for example.
Set how to reverse the bits of the input. None
means no reversal.
Set whether to reverse the bits of the output.
Set whether to reflect the CRC. When enabled, reflection is
BitReversal::Byte
and output reversal enabled. This is simply
a convenience function as many CRC algorithms call for this.
Set the value to XOR the output with. Automatically masked to the proper size.
