Andrew Leech	8ed4a28dae	stm32/sdram: Increase GPIO speed for SDRAM interface to "very high". Currently all usages of mp_hal_pin_config_alt_static() set the pin speed to "high" (50Mhz). The SDRAM interface typically runs much faster than this so should be set to the maximum pin speed. This commit adds mp_hal_pin_config_alt_static_speed() which allows setting the pin speed along with the other alternate function details.	2019-02-20 16:54:32 +11:00
Andrew Leech	4343c9330e	stm32: Add method for statically configuring pin alternate function. Works with pins declared normally in mpconfigboard.h, eg. (pin_XX), as well as (pyb_pin_XX). Provides new mp_hal_pin_config_alt_static(pin_obj, mode, pull, fn_type) function declared in pin_static_af.h to allow configuring pin alternate functions by name at compile time.	2018-07-20 14:03:21 +10:00

stm32/sdram: Increase GPIO speed for SDRAM interface to "very high".

Currently all usages of mp_hal_pin_config_alt_static() set the pin speed to
"high" (50Mhz).  The SDRAM interface typically runs much faster than this
so should be set to the maximum pin speed.

This commit adds mp_hal_pin_config_alt_static_speed() which allows setting
the pin speed along with the other alternate function details.

stm32: Add method for statically configuring pin alternate function.

Works with pins declared normally in mpconfigboard.h, eg. (pin_XX), as well
as (pyb_pin_XX).

Provides new mp_hal_pin_config_alt_static(pin_obj, mode, pull, fn_type)
function declared in pin_static_af.h to allow configuring pin alternate
functions by name at compile time.
