CMSIS-DSP low-level bindings
Configuring and using the bindings
Different versions of the library will be linked depending on the type of processor the code will run on. You may need to enable some Cargo features depending on the target:
- Cortex-M7: Enable the feature
cortex-m7. Also, if the processor has a double-precision floating point unit, enable thedouble-precision-fpufeature. - Cortex-M33 (target
thumbv8m.main-none-eabiorthumbv8m.main-none-eabihf): If the processor supports DSP instructions, enable thedsp-instructionsfeature.
All other targets will be configured automatically based on the target passed to cargo. If you forget to enable a feature, everything should still work but it may be slower.
