问 Semaphore inside ISR

发布于9年前

Thanks. But what will cause the ISR context to block? Some RTOSes has special functions to call only inside ISR. Why RT-Thread have not?

Hi Bernard,

Thanks for your reply. It’s all clear to me now.

问 RTThread Licence

发布于10年前

Bernard. Could you clear this question? Can I use this RTOS in a commercial application without expose my application code?
If no, why not modify the RTThread licence to one like FreeRTOS?

I believe that RTThread has potential to be great in commertial applications.

问 RT-GUI Macro Error

发布于10年前

I’m trying to compile the demo_listview_icon.c from the RTGUI demo folder. I’ve downloaded RTGUI 0.8 and I believe that the demo examples are outdated. There was some headers files that was not found in the source code, for example “toplevel.h”. Do exist a new RTGUI version for download? Is correct the use of the code bellow in the demo_listview_icon.c?

application = RTGUI_APPLICATION(rtgui_widget_get_toplevel(widget));

Is there some manual in english format for RTGUI or RTThread?

Where can I configure my LCD driver and Touch driver to RTGUI use them?

Regards.

((type )NULL)

问 RT-Thread GCC Compiler Error

I’m using LPC176x bsp and using eclipse with your default make build tool, but this error is not a build error and a compile error. The compiler don’t acepts this macro because it found a sintax error. Did you compile the RT-Thread 1.2.0 with GCC?
