From 93b063fedfcf7409a67df035170ea5670cad22e1 Mon Sep 17 00:00:00 2001 From: Josh Rahm Date: Tue, 24 Nov 2020 13:46:41 -0700 Subject: Moved action to top level. Removed old iterations of the project and moved the files from 02-usart to the root directory since that's the sole place where the action is and that subproject has outgrown its initial title. --- 01-system-clock/src/main.c | 36 ------------------------------------ 1 file changed, 36 deletions(-) delete mode 100644 01-system-clock/src/main.c (limited to '01-system-clock/src/main.c') diff --git a/01-system-clock/src/main.c b/01-system-clock/src/main.c deleted file mode 100644 index 7912bf2..0000000 --- a/01-system-clock/src/main.c +++ /dev/null @@ -1,36 +0,0 @@ -#include "clock.h" -#include "delay.h" -#include "gpio.h" -#include "spin.h" - -volatile uint32_t delay_amt = 20000000 / 4; - -/* Main function.
