sloop is an embedded bare-metal framework that provides a set of APIs to facilitate the management of multiple tasks, such as timeout tasks/cyclical tasks/parallel tasks/mutex tasks, etc.
There are two non-blocking waiting APIs, sys_wait and sys_wait_bare, which support suspending the current mutually exclusive tasks, but not blocking parallel tasks.
Tasks adopt dynamic registration mechanism, which has the following advantages:
1. It can be easily enabled and stopped at runtime, without any side effects after stopping.
2. It can replace partial static calls to simplify call coupling between files.
3. It can replace the operation of synchronizing the number of flags, effectively reducing the number of flags used and increasing the readability of the code.
Update log:
2025-3-11
feat: Added GPIO output command on the console
feat: Added gpio input echo switch on the console
2025-3-10
feat: streamline GPIO API
2025-3-3
feat: a brand new gpio configuration template
optimiz: Remove system API: sys_wait_for and sys_delay_nonblock
optimiz: simplify demo logic
feat: readme.txt Join mdk project
2025-2-27
feat: add some design suggestions to readme
feat: Added common memory illegal operation tips
2025-2-26
feat: both uart1~6 are verified and the console provides uart sending support
2025-2-19
feat: hardfault adds stack resolution and throws the location of the suspected error code (i.e. address)
2025-2-13
feat: readme new directory structure description
2025-2-8
feat: Added task cycle statistics, and the console task on command can be viewed.
2025-2-7
feat: Use Note Add Best Practices on Interrupt Handling.
feat: Added us-level delays sys_delay_us and sys_get_us, which are precisely timed through tim7, but no interruption occurs.
2025-2-2
optimiz: Modify the print log api name, for example, sys_printf_func is modified to sys_prt_withFunc.
feat: Add -h to view the command using examples, such as uart -h.
2025-1-27
feat: The communication port serial port and can configuration are integrated in com_config.h. service_api.h summarizes the service layer api.
2025-1-24
feat: Added parallel tasks and periodic task queries on the console, and enable behavior logs to take effect.
feat: The console serial port and can support sending hexadecimal. Command format uart -hex 30 31 ..., without -hex, the default ASCLL code is sent.
2025-1-23
feat: can support FIFO
2025-1-20
feat: The console adds a query mcu load command.
feat: Remove API sys_cycle_flag_start.
feat: The soft-timed task no longer runs in ms interrupts, and is changed to the main thread loop. It helps to reduce stack space, reduce stack entry and exit, and improve system performance and stability.
feat: The interrupt is changed to level 16 response priority, and no longer supports preemption, which helps reduce stack space, reduce stack entry and exit, and improve system performance and stability.
There will be no deadlock problem anymore. However, interrupt processing is required to be clean and neat, process real-time data, and exit quickly.
2025-1-16
feat: serial port receiving DMA + FIFO OK
feat: base_init is changed to task task_baseInit. That is, the ancestor task.
2025-1-15
feat: Serial port send DMA + FIFO OK
feat: Refactor the mutex task, and change the original static call to dynamic call.
feat: Added _FREE and _RUN to facilitate the release of resources at the end of the task. For example, periodic tasks.
2025-1-14
feat: The serial port supports DMA transmission and reception
feat: The console adds a task command to query the current task. Mutex tasks need to implement INIT before they can support queries.
2025-1-13
feat: Add idle idle task, and the mutually exclusive task can be done or stay in idle.
feat: Added task_end mutex task recycling function.
It releases some resources that are enabled in the current task, such as periodic tasks, before jumping to other tasks, so you don't need to do the release operation before each sys_goto.
Weak definition, implemented according to requirements, may not be implemented.
feat: Add multiple tasks on the basis of periodic tasks, and specify the number of executions and intervals. It can be used for multiple buzzer calls and multiple regular resends on the serial port.
feat: Add sys_wait_bare non-blocking naked wait until break or continue. No need to pass in waiting conditions. Applicable to multiple conditions.
It is equivalent to suspending, and the external interrupt is through sys_wait_break or sys_wait_continue.
feat: Added sys_is_waiting to query the waiting status.
feat: The console adds a query version command version, which can be set through sys_set_version.
2025-1-10
feat: Added buzzer driver, supports multiple buzzing
feat: Added a new running light driver
2025-1-9
Added new parameter saving driver and demonstration, Flash is used as storage medium by default, and can be configured as EEP (EEP has a 32-byte limit).
2025-1-6
A new system console is added, and preset commands can be executed on the RTT terminal, such as inputting reboot to perform restart. Enter m to exit the menu.
Support input parameters, such as test -p 6.88
The console can be used for initial online debugging hardware, online debugging sports, etc.
2025-1-4
Added a single task API sys_task_once, which is executed only once and is lagged to the loop. Can be used for decentralized execution of complex logic in interrupts.
2024-12-31
Added a configurable enable watchdog, timeout time of 1s, not enabled by default.
Added behavior logs, which can be enabled in bl_config.h, to facilitate analysis of business workflows.
New timestamp for logs [day h:m:s.ms]
2024-12-30
Added a system heartbeat, printed in terminal1 window, which can be used to determine whether the crash is delayed.
2024-12-25
Simplify mutually exclusive tasks
Added error log, print source code location sys_error
Added variable print macro sys_prt_var
2024-12-20
