# CH32F10X系列BSP移植
|
||||
## 1 工程结构
|
||||
+ wch\arm\ch32f103c8-core
|
||||
+ wch\arm\Libraries
|
||||
+ wch\arm\Libraries\ch32_drivers
|
||||

|
||||
+ wch\arm\tools
|
||||
|
||||
ch32f103c8-core为移植到具体芯片的BSP, Libraries存放的是厂商的驱动库(CH32F10x_StdPeriph_Driver等)和适配rt-thread的驱动(ch32_drivers),
|
||||
tools是在env环境下使用scons --dist所需要的依赖工具
|
||||
|
||||
### 1.1 已适配rt-thread的驱动(ch32_drivers)：
|
||||
现已支持以下驱动(支持的驱动，使用到的宏开关，需要实现的接口)：

|
||||
~~~c
|
||||
void ch32f1_i2c_clock_and_io_init(I2C_TypeDef* i2cx);
|
||||
void ch32f1_i2c_config(I2C_TypeDef* i2cx);
|
||||
~~~
|
||||

|
||||
~~~c
|
||||
void ch32f1_tim_clock_init(TIM_TypeDef *timx);
|
||||
rt_uint32_t ch32f1_tim_clock_get(TIM_TypeDef *timx);
|
||||
~~~
|
||||
~~~c
|
||||
struct rt_hwtimer_info* ch32f1_hwtimer_info_config_get(TIM_TypeDef *timx);
|
||||
~~~
|
||||
+ PWM 4(timer) x 4 (channel)
|
||||
+ RT_USING_PWM
|
||||
+ BSP_USING_TIM1_PWM
|
||||

|
||||
~~~c
|
||||
void ch32f1_pwm_io_init(TIM_TypeDef *timx, rt_uint8_t channel);
|
||||
~~~
|
||||
其中需要依赖定时器的接口：
|
||||
~~~c
|
||||
void ch32f1_tim_clock_init(TIM_TypeDef *timx);
|
||||
rt_uint32_t ch32f1_tim_clock_get(TIM_TypeDef *timx);
|
||||
~~~
|
||||
|
||||
|
||||
### 1.2 需要实现的接口：
|
||||
除了使用上面驱动提及的接口外，以下的接口必须实现：
|
||||
~~~c
|
||||
rt_uint32_t ch32_get_sysclock_frequency(void);
|
||||
~~~
|
||||
## 2 构建具体芯片BSP
|
||||
以ch32f103c8-core为例，在ENV环境下，使用MDK，至少需要准备
|
||||
+ ch32f103c8-core (具体的BSP名)
|
||||
+ ch32f103c8-core\applications
|
||||
+ ch32f103c8-core\applications\SConscript
|
||||
+ ch32f103c8-core\applications\main.c
|
||||
+ ch32f103c8-core\board
|
||||
+ ch32f103c8-core\board\linker_scripts
|
||||
+ ch32f103c8-core\board\linker_scripts\link.sct
|
||||
+ ch32f103c8-core\board\board.c
|
||||
+ ch32f103c8-core\board\board.h
|
||||
+ ch32f103c8-core\board\ch32f10x_conf.h
|
||||
+ ch32f103c8-core\board\system_ch32f10x.c
|
||||
+ ch32f103c8-core\board\Kconfig
|
||||
+ ch32f103c8-core\board\SConscript
|
||||
+ ch32f103c8-core\Kconfig
|
||||
+ ch32f103c8-core\rtconfig.py
|
||||
+ ch32f103c8-core\SConscript
|
||||
+ ch32f103c8-core\SConstruct
|
||||
+ ch32f103c8-core\template.uvprojx
|
||||
|
||||
### 2.1 创建template.uvprojx
|
||||
新建名为template的MDK工程，删除多余的子目录target1，将目录改名为rtthread-ch32f103x，options选项栏device设置具体芯片，user编译后的动作, 如"fromelf --bin !L --output rtthread.bin"
|
||||
|
||||
### 2.2 编写board/Kconfig
|
||||
|
||||
~~~
|
||||
menu "Hardware Drivers Config"
|
||||
|
||||
config SOC_CH32F103C8
|
||||
bool
|
||||
select SOC_ARM_SERIES_CH32F103
|
||||
select RT_USING_COMPONENTS_INIT
|
||||
select RT_USING_USER_MAIN
|
||||
default y
|
||||
~~~
|
||||
SOC_CH32F103C8为具体的芯片，SOC_ARM_SERIES_CH32F103在Libraries\Kconfig下已定义。
|
||||
RT_USING_COMPONENTS_INIT，RT_USING_USER_MAIN为rt-thread设备框架默认选项。
|
||||
|
||||
|
||||
使用适配的驱动根据宏开关编写即可，以串口驱动为例：
|
||||
+ BSP_USING_XXX
|
||||
+ select RT_USING_XXX
|
||||
+ BSP_USING_XXX1
|
||||
+ BSP_USING_XXX2
|
||||
|
||||
~~~
|
||||
menu "On-chip Peripheral Drivers"
|
||||
|
||||
config BSP_USING_UART
|
||||
bool "using onchip usart"
|
||||
select RT_USING_SERIAL
|
||||
default n
|
||||
|
||||
if BSP_USING_UART
|
||||
config BSP_USING_UART1
|
||||
bool "using uart1"
|
||||
default n
|
||||
|
||||
config BSP_USING_UART2
|
||||
bool "using uart2"
|
||||
default n
|
||||
|
||||
config BSP_USING_UART3
|
||||
bool "using uart3"
|
||||
default n
|
||||
endif
|
||||
~~~
|
||||
|
||||
比较特殊的定时器和PWM驱动额外定义了以下宏开关，详见ch32f103c8-core。
|
||||
+ BSP_USING_TIM
|
||||
+ BSP_USING_TIM1
|
||||
+ BSP_USING_TIM2
|
||||
+ BSP_USING_TIM3
|
||||
+ BSP_USING_TIM4
|
||||
### 2.3 在board/board.h加入接口，并在board/board.c实现
|
||||
使用适配的驱动根据宏开关编写即可,如串口驱动：
|
||||
+ BSP_USING_XXX
|
||||
~~~
|
||||
#ifdef BSP_USING_UART
|
||||
void ch32f1_usart_clock_and_io_init(USART_TypeDef* usartx);
|
||||
#endif
|
||||
~~~
|
||||
比较特殊的定时器和PWM驱动使用额外定义了的宏开关
|
||||
~~~c
|
||||
#ifdef BSP_USING_TIM
|
||||
void ch32f1_tim_clock_init(TIM_TypeDef *timx);
|
||||
rt_uint32_t ch32f1_tim_clock_get(TIM_TypeDef *timx);
|
||||
|
||||
#ifdef BSP_USING_HWTIMER
|
||||
struct rt_hwtimer_info* ch32f1_hwtimer_info_config_get(TIM_TypeDef *timx);
|
||||
#endif
|
||||
|
||||
#ifdef BSP_USING_PWM
|
||||
void ch32f1_pwm_io_init(TIM_TypeDef *timx, rt_uint8_t channel);
|
||||
#endif
|
||||
#endif
|
||||
~~~
