Detailed Description

CRTP SPI communication adapter for MAX22200 using BaseSpi and BaseGpio.

Implements all methods required by max22200::SpiInterface<HalSpiMax22200Comm>. Handles the two-phase CMD-pin SPI protocol.

Constructor & Destructor Documentation

HalSpiMax22200Comm()

HalSpiMax22200Comm::HalSpiMax22200Comm ( BaseSpi & spi, BaseGpio & enable, BaseGpio & cmd, BaseGpio * fault = nullptr )

noexcept

Construct the SPI adapter.

Parameters

spi	Reference to pre-configured BaseSpi (Mode 0, 8-bit).
enable	BaseGpio for ENABLE pin (active HIGH).
cmd	BaseGpio for CMD pin (HIGH=command phase, LOW=data phase).
fault	Optional BaseGpio for nFAULT (active LOW, open-drain).
