Function Documentation

uint8_t TM_SDRAM_Init

(

void

)

Initializes SDRAM.

Parameters

None

Return values

SDRAM

status 0: SDRAM is not configured OK > 0: SDRAM is configured OK and prepared to work

uint8_t TM_SDRAM_InitCustomPinsCallback

(

uint16_t

AlternateFunction

)

Initialize custom pins callback. It can be used by user to implement custom pins for application if needed.

Note

This function is called every time TM_SDRAM_Init() function is called

Parameters

AlternateFunction

Alternate function to be used when initializing GPIO pins

Return values

Initialization

status: 0: User did not initialize custom pins, default will be used, depending on already supported boards > 0: User has initialized custom pins, default pins will be ignored

Note

With __weak parameter to prevent link errors if not defined by user
