SPIFlash API

For full per-call detail, use the SPIFlash Function Reference.

Functional groups

• Initialization: begin, setClock, sfdpPresent
• Identification: getJEDECID, getUniqueID, getCapacity, getMaxPage
• Addressing helpers: getAddress, sizeofStr
• Read/write primitives and arrays
• Generic IO: writeAnything, readAnything
• Erase operations: sector/block/chip/section
• Power and suspend/resume

Behavioral notes

• Writes are page-aware and support page-boundary spanning.
• Write verification is enabled by default.
• Erase timing comes from defaults or SFDP when enabled.
