From 8eea37e61e919819e6ef51d8a1c1bd04cfd0892a Mon Sep 17 00:00:00 2001 From: "Pavel V. Shatov (Meister)" Date: Sun, 22 May 2016 14:21:03 +0300 Subject: Initial commit of code, that initializes the two on-board SDRAM chips. Includes simple memory test program. Note, that there turns out to be a bug in low-level HAL driver, so this commit includes corrected stm32f4xx_ll_fmc.c --- gpio.c | 95 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 95 insertions(+) create mode 100644 gpio.c (limited to 'gpio.c') diff --git a/gpio.c b/gpio.c new file mode 100644 index 0000000..d24af2a --- /dev/null +++ b/gpio.c @@ -0,0 +1,95 @@ +/** + ****************************************************************************** + * File Name : gpio.c + * Description : This file provides code for the configuration + * of all used GPIO pins. + ****************************************************************************** + * + * COPYRIGHT(c) 2016 STMicroelectronics + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * 1.
