掌機 - Miyoo Mini Plus - GPIO Address

位址如下

U32 gChipBaseAddr    = 0x1F203C00;
U32 gPmSleepBaseAddr = 0x1F001C00;
U32 gSarBaseAddr     = 0x1F002800;
U32 gRIUBaseAddr     = 0x1F000000;

計算方式

#define MHal_CHIPTOP_REG(addr)  (*(volatile U8 *)(gChipBaseAddr    + (((addr) & ~1) << 1) + (addr & 1)))
#define MHal_PM_SLEEP_REG(addr) (*(volatile U8 *)(gPmSleepBaseAddr + (((addr) & ~1) << 1) + (addr & 1)))
#define MHal_SAR_GPIO_REG(addr) (*(volatile U8 *)(gSarBaseAddr     + (((addr) & ~1) << 1) + (addr & 1)))
#define MHal_RIU_REG(addr)      (*(volatile U8 *)(gRIUBaseAddr     + (((addr) & ~1) << 1) + (addr & 1)))

例如：GPIO11_IN = (0x1f20782c & (1 << 0))

(*(volatile U8 *)(0x1F000000 + (((0x103C16) & ~1) << 1) + (0x103C16 & 1))) = 0x1f20782c
