README.mdVSF -- 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 interfaces and functionalities
- interfaces
- PM
- GPIO
- SPI
- I2C
- PWM
- ADC
- SWI
- USART
- FLASH
- USB
- ethernet

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

Questions
How big is the Gamepad PCB?
It measures 155.8 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gamepad use?
100 parts, built around the ADS7830IPW, 74HC165D, 74HC595 and AO3402. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Gamepad KiCad files?
From the vsfteam/vsf repository on GitHub, at the commit this page was made from: the board is hardware/ext/gamepad/gamepad.kicad_pcb and its schematic hardware/AC6321A/vsf_ac6321a.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gamepad design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
