kandi X-RAY | OSAL Summary
大学的时候用过 TI 的 ZigBee 和 BLE,里面都有一个 轮询式的操作系统 OSAL,小巧灵活,并且适合学习。在单片机上开发大家都了解,一般的开发流程是,修改代码 -> 编译(速度慢) -> 下载 -> 复位单片机 -> 看现象。从改程序到看到现象步骤繁多,容易让初学者在繁杂的步骤中失去信心。当时为了克服这个学习困难把 OSAL 抽离了出来,放在了 VS 环境下。编译速度和学习的方便程度都有很大提高 。最近在整理东西,再次把它拿出来,希望对大家有所帮助。. 注 : 因为OSAL组件的不同,这次移植参考了 CC2541的 协议栈源码,CC2538的协议栈源码,和CC2630的协议栈源码, 争取在剥离出来的时候做到对官方源码的最少的改动,对官方代码模块的最大包含。.

QUESTION
I would like to compile my own project. I have error with **make**
. cmake ..
works properly.
I tried to compile the example in /Onboard-SDK/sample/platform/telemetry. I did mkdir build and cd build in telemetry directory.
This is my CMakeList.txt

QUESTION
I am trying to write a copy file function that can be used on both Linux and Windows. It works on Linux, but on Windows, I get error code 5 when trying to use the WinApi function CopyFile().
In header File.h
This is the custom defined function in the File namespace that I should be able to use on both Linux and windows.
...ANSWER
Answered 2017-Jul-15 at 07:55The CopyFile API expects file names for both source and destination files. Your code passes a directory name for the destination. This causes the API to fail. You need to append the file name for the destination as well.
Besides that, there are several other issues with your code:
- The path separator on Windows is a backslash (
\
). Your are mixing forward slashes (/
) and backslashes. Depending on the arguments passed, the system won't translate forward slashes to backslashes, before passing them on to lower-level file I/O API's. - You are calling
GetLastError
too late. You need to call it immediately, whenever it is documented to return a meaningful value. Do not intersperse it with any other code, however trivial it may appear to you. That code can modify and invalidate the calling thread's last error code. - Your code assumes ASCII-encoded strings. This will stop working, when dealing with files containing non-ASCII characters. This is quite common.
new wchar_t[...]
buys you nothing overstd::vector
, except the possibility to introduce bugs.- Your MultiByteToWideChar-based string conversion implementation makes (undue) assumptions about the code unit requirements of different character encodings. Those assumptions may not be true. Have the API calculate and tell you the destination buffer size, by passing
0
for cchWideChar. - Your string conversion routine ignores all return values, making bugs ever so likely, and unnecessarily hard to diagnose.
QUESTION
I am working to assign a pointer to a double within C++. When I take the pointer out it runs fine however as soon as I run it with the pointer I get an error saying "cannot convert 'double*' to 'double' in assignment". I cannot figure out why this is giving me this error. Any help is greatly appreciated.
...ANSWER
Answered 2019-Feb-10 at 23:48Pointers in C++ are a little bit different than their C counterpart.
It should be invoked using the keyword new
for efficient memory management.
double *pbsal = new double[2];
Now pbsal[0]
and pbsal[1]
are just double values. And the loop should be i<2
not i<=2
.
QUESTION
My project has structure with many subfolders. I managed to collect all of the C files into SOURCES
variable and now I want to compile all the files with the same rule. Since my C files have many different locations I can not just use a simple pattern rule like %.o: %.c
. Searching revealed the solution to exactly the same problem however it does not work for me. For some reason my function define_compile_rules
is not ever called. Why, I have no ideas.
ANSWER
Answered 2018-Jan-06 at 19:30The "main" rule app
(thats builds all that needs to be build) must have as dependency the needed files (the object files). This way make
will first build them by calling the appropriate rule.
Thus, you rule needs to be:
QUESTION
I'm trying to create OSAL (Operating System Abstraction Layer) adapter for FreeRTOS but confused with the provided interfaces.
For example, init function of RiCOSTask is defined as follows in the docs :
...ANSWER
Answered 2017-Apr-10 at 11:56The documentation is written for the OXF, not for the SMXF Framework. As far as I know there is no real documentation for adapting an SMXF but.. the SMXF is there as a model (Check your /LangC/smxf directory) this should make it easier to create an adapter. Do you really need the SMXF or would an OXF suffice (or even another Framework like RXF?
