Versaloon Software Framework -- a tiny preemptive-capable event-driven incremental software framework for embedded systems

VSF -- Versaloon Software Framework

中文 |

Full name of VSF is "Versaloon Software Framework". VSF is an open-source software framework for embedded applications based on Apache2 license. VSF includes hal, a pre-emptive multi-thread kernel, services and components. VSF is implemented by C language with object-oriented programming methods(PLOOC).

Kernel

Pre-emptive kernel based on event-driven architecture, supporting mcs51, 8bit MCU, 32/64 bit ARM, riscv, x86, etc.

• event-driven architecture, sleep if no event occurred, lower-power naturally
• in pre-emptive mode, task switch is implemented by hardware swi(software interrupt), priority of task is the priority of the swi.
• pre-emptive scheduling for tasks with different priority, collaborative scheduling for tasks with the same priority
• can run in other RTOS as a task, or as swi ISR
• different tasks
  • event handler task -- minimum resources usage, 20 bytes ram usage for minimum configuration, 40 bytes ram usage for normal configuration
  • pt task
  • thread with dedicated stack -- depending on setjmp in libc
  • fsm task
  • other tasks in shell, eg pthread
• IPC: semaphore, mutex, trigger, queue, etc

Components

• Reasonable framework for code re-use
• declarative development model
• standard interface, standard port for 3rd-party components
• software components
  • distbus -- distributed bus framework
  • fifo
  • heap
  • json
  • pool
  • stream
  • trace
• Components
  • fs -- filesystem with vfs support
  • input -- input sub-system
  • mal -- memory abstraction layer(normally known as 'block' device)
  • scsi -- SCSI device
  • tcpip -- TCPIP stack and netdrv drivers
  • ui -- UI and display drivers
  • usb -- USB host/slave stacks
  • bt -- bt stack(using btstack)

HAL -- hardware abstraction layer

• standard hal interface and API -- eg: vsf_spi_init can be used with hardware SPI, GPIO emulated SPI, SPI from external usb device, etc
• IP core driver -- simplify porting by implement clock, reset, interrupt functions which is not provided by IP core
• template for different intefaces and functionalities
• interfaces
  • PM
  • GPIO
  • SPI
  • I2C
  • PWM
  • ADC
  • SWI
  • USART
  • FLASH
  • USB
  • ethernet

Shell

To use applications from other system, shell can be used.

• SDL -- use applications based on SDL directly
• linux -- use applications based on linux directly
  • posix
  • devfs
  • socket
  • console
  • libraries
    • libusb
    • libgen
    • libsdl2
    • libcurl
    • etc

vsf's Issues

请问vsf支持装载运行elf吗？

请问vsf支持装载运行elf吗？谢谢

[hal] IO模块的宏需要更新

修改 IO 模块的 VSF_HW_IO_{PORT,PIN}MAX 到 VSF_HW_IO{PORT,PIN}_{COUNT,MASK}

Event-Driven-Architecture 可以适配其他RTOS 比如freertos 和zephyr 等？

类似 于 QP™ Real-Time Embedded Frameworks ,QP包括事件处理器(QEP)、轻量级的事件驱动框架(QF)可以使用其他的RTOS.

vsf_gpio_output_and_set/vsf_gpio_output_and_clear加详细说明注释

为了避免IO方向改变引起的脉冲，才需要使用的API。

hal中的中断，评估是否需要增加enter/leave，来调用RTOS的对应接口

如题

Example CMake Error

您好，感谢您贡献的 vsf。我在尝试编译 vsf/example/template/project/cmake/esp32s2 示例工程时，出现了多处 CMake Error ，应该是之前您有一次提交改变了工程的目录结构导致，尝试修改关联的 CMakeLists 最终也没编起来，报了 Unknown CMake command "add_subdirectory_ifdef" 我在最新的 CMake 文档中未找到这个 API ，请问需要特殊的处理步骤吗？

hal/driver/common下的模板，尽量做到通用

目前尝试，usart的fifo2req模板，只能针对hw_usart，不能通用，其他usart实例无法使用。

hal里，有些类型加了vsf前缀，有些没加

比如，vsf_gpio_t加了前缀，gpio_capability_t没加前缀。
修改的话，需要同步修改github.com/vsfteam/vsf.demo里的代码。

vsf_template_spi.h中的编译警告

一些枚举的类型，不一定只是8位的，hal中没有这个要求。
hal里其他接口也确认是否有类似的问题

aic8800里运行gpio demo出错

使用默认IAR工程，短接PA10和PB3引脚。

预期输出是

read pin value: 0x00000000
read pin value: 0x00000400
read pin value: 0x00000000
read pin value: 0x00000400
......

实际输出是：

read pin value: 0x00000000
read pin value: 0x00000000
read pin value: 0x00000400
read pin value: 0x00000000
read pin value: 0x00000400
......

添加f1c100s和m484到CI里

• f1c100s
• m484

hal应该避免导出来自驱动的头文件，需要提供一个专用的头文件给上层来包含

I2C对会自动发送STOP的硬件的支持

如题

linux.spi代码的一些细节问题

对于最新增加的linux下的spi的代码

1. 缩进使用4个空格，不适用tab。 -- VSF代码缩进规则
2. __vsf_linux_spi_config里，不应该依赖i2c
3. __vsf_linux_spi_ioc_transfer和spi_ioc_transfer结构，这里并没有看出明显的ioc层
   vsf的命名规范可以在表示层次结构的'_'改成'.'。比如：__vsf_linux_spi_ioc_transfer表示private vsf.linux.spi.ioc.transfer
   如果没有明显的ioc层的话，命名上不需要加ioc

flash_mal里调用flash接口API的方式，不符合flash接口API的规范

flash接口API的规范上，不是阻塞的调用。即使有一些芯片的flash操作是阻塞的，但是flash接口API的规范仍旧是非阻塞的。

i2c的multiplex实现

注意复用的时候，是从start开始，到了stop之后，才能复用下一个。

pwm的lv0接口里，有一些用户层的API

底层接口上，应该没有ms/us/ns等信息，只有时钟周期信息

hal中get_transfered_count的API拼写错误

应该是transferred，而不是transfered

mipi_spi_lcd中，最简用户层封装不依赖mipi命令和参数

需要翻译成人类可以直接理解的定义，而不是mipi的命令和参数

vsf json

vsf_json_get_number, 应该删掉引号判断代码
if (*json++ != '"') {
return -1;
}
考虑添加isdigit，判断

使用armclang编译有大量的'-Wcast-align'警告

GPIO的capability里，增加对应的port的可用引脚的MASK

更新hal里关于init/enable/disable的注释

需要是补充说明各个api的调用先后顺序

IIC操作的时候，在提前NAK的情况下，如何得到已经传输的数据长度？

multiplex_spi.c编译警告修复

VC下，llvm编译器：

AIC8800M的GPIOB0只能输入，不能输出，但是vsf_hw_gpio_set_output不会返回错误

如题

i2c capability里增加mtu

AIC8800M的I2C的MTU是16，在capability里提供。
有些芯片的驱动是可以根据mtu做workaround的。

vsf_i2c_cfg_t中的模式类型，不应该是vsf_i2c_feature_t，而应该是vsf_i2c_mode_t

如何，其他驱动中不确定是否也有类似的命名问题。

如果类型使用vsf_i2c_feature_t，变量名建议使用feature
如果类型使用vsf_i2c_mode_t，变量名建议使用mode

增加 wdt / dma / 外部中断

GPIO的cap中，加入位宽信息

如题

W600 svd?

You seem to have added some basic support for the W600 chip, do you happen to have the svd files?

disp_demo AIC8800M 显示缓冲在heap中的测试

之前测试，显示缓冲放在heap中（heap位于0x00100000开始的320K内存中），其他不变，显示会有问题。

Low power mode + document

提供低功耗模式的示例和文档。特别是在 AIC8800 上

hal/io 的 模式需要完善，也需要补上外部中断 的 hal 模板

hal template 修复因为头文件包含顺序导致枚举类型值不一致的问题

hal里的vsf_*_capability_t里应该包含各个中断是否支持的信息

vsfsm.c

fsm framework 这个不打算再支持了？

增加vsf_tempalte_dac.h，并且重新默认使能VSF_HAL_USE_DAC

如题，VSF_HAL_USE_DAC已被临时关闭

hal 里面的中断的优先级不能假设一定高于调用 hal api 的任务优先级

目前部分代码不满足这个要求，例如 multiplex_i2c

使用说明文档 太少，建议提高
