【萌新】D1H如何使用硬件定时器？
-
想使用硬件定时器输出步进电机的脉冲，我看D1H的用户手册是有这个功能的（手册里提供了直接操作寄存器的代码例子），但是不太明白如何在应用层调用，是否是没有对应的驱动？
网上查找了一些定时器相关的代码，编译报错找不到头文件/home/ubt/tina-d1-h/prebuilt/gcc/linux-x86/riscv/toolchain-thead-glibc/riscv64-glibc-gcc-thead_20200702/bin/riscv64-unknown-linux-gnu-gcc -o timer timer.c timer.c:14:10: fatal error: linux/timer.h: No such file or directory #include <linux/timer.h>我看了下在tina-d1-h\lichee\linux-5.4\include\linux这个目录下是有timer.h这个头文件的，但是没有高精度定时器hrtimer.h的文件
之前基本只搞过单片机裸板开发，linux驱动/应用开发都还在学习中，现在是搞不太明白，还望大佬指点
-
在out目录下搜索存在hrtimer.h文件，但是该如何调用？
是menuconfig中有timer的相关配置需要开启吗 -
config-5.4文件搜索timer配置如下
# # Timers subsystem # CONFIG_TICK_ONESHOT=y CONFIG_NO_HZ_COMMON=y # CONFIG_HZ_PERIODIC is not set CONFIG_NO_HZ_IDLE=y CONFIG_NO_HZ=y CONFIG_HIGH_RES_TIMERS=y # end of Timers subsystem # # Clock Source drivers # CONFIG_TIMER_OF=y CONFIG_TIMER_PROBE=y CONFIG_CLKSRC_MMIO=y CONFIG_SUN4I_TIMER=y # CONFIG_SUN50I_TIMER is not set # CONFIG_SUNXI_TIMER is not set # CONFIG_SUNXI_TIMER_TEST is not set # CONFIG_MTK_TIMER is not set CONFIG_RISCV_TIMER=y # end of Clock Source drivers看起来也都是开启的，就是不知道咋用
-
include 的路径对吗，加入了-I 的头文件指定路径吗，或者KERNEL的prefix对吗
-
@yuzukitsuru 代码头文件是这样的
#include <linux/module.h> #include <linux/kernel.h> #include <linux/hrtimer.h> #include <linux/jiffies.h>makefile没有加-l指定路径
#设置编译链路径及工具 CTOOL := riscv64-unknown-linux-gnu- CCL := /home/ubt/tina-d1-h/prebuilt/gcc/linux-x86/riscv/toolchain-thead-glibc/riscv64-glibc-gcc-thead_20200702 CC := ${CCL}/bin/${CTOOL}gcc #设置编译规则 timer:timer.c ${CC} -o timer timer.c #清理规则 clean: rm timer但是编译时没有报错找不到module.h或者kernel.h
prefix不太清楚我去找一下
-
想参考下头文件路径该指定哪里
搜索了package下的文件,都没有调用timer的;
直接搜索整个SDK太大了,在out目录下找到很多,但这里似乎只是存放各种板型生成文件的地方没啥用
总之还是没解决 -
@allwinner_account 可以参考这个 https://v853.docs.aw-ol.com/soft/dev_gpio/#linux-led 编写一个kernel驱动即可
-
@yuzukitsuru 好的感谢回复,我以为可以不用写驱动来着
-
还是尝试找了下头文件位置,参考linux内核目录介绍和搜索功能,添加了一些路径
