Detailed Description

template<typename CommType>
struct tmc9660::TMC9660< CommType >::NvmStorage

Subsystem for storing and recalling parameters from nonvolatile flash.

This API wraps STAP (0xFFF) and FactoryDefault commands. Use it to persist all RWE parameters across power cycles, matching the functionality of the “Save to Flash” button in GUI tools.

WARNING: Requires that external memory is configured via BOOT_CONFIG. Refer to the "Storing System Settings" section in the datasheet (see page 15).

Member Function Documentation

eraseFlashBank()

template<typename CommType >

bool tmc9660::TMC9660< CommType >::NvmStorage::eraseFlashBank ( uint8_t n )

noexcept

Erase a configuration bank from external memory.

Parameters

n	Index of the flash bank to erase (typically 0)

Returns

true if erase command sent successfully.

Use before re-storing to flash if stale config causes issues.

recallFromFlash()

template<typename CommType >

bool tmc9660::TMC9660< CommType >::NvmStorage::recallFromFlash ( )

noexcept

Restore parameters previously saved to NVM.

Returns

true if configuration was successfully recalled.

Sets CONFIG_LOADED flag in GENERAL_STATUS_FLAGS if success.

storeToFlash()

template<typename CommType >

bool tmc9660::TMC9660< CommType >::NvmStorage::storeToFlash ( )

noexcept

Store all writable parameters to flash or EEPROM.

Returns

true if the operation completed without error.

Internally sends STAP (type=0xFFF) to save parameters.
