Best way to mate interrupts with c++ periephal drivers?

Hey!​Lets say I write general Can periephal driver in c++ for stm32f4 series(which I'm actually doing), then interrupt handlers for can1 and can2.​Now the proplem is how do I tell lets say can 1 rx interrupt, that >>this instance of object<< is the ...

__set_BASEPRI -- implicit declaration

__set_PRIMASK(1); // No error __set_BASEPRI(3 << 4); // Implicit declarationThis is a snippet of my code from keil uvision5. But, the IDE results in a syntax error; implicit declaration of function ' __set_BASEPRI ' is inval...

Could you give me some reason, why after run receiving I2S via DMA, the handler at half and full of fill of a buffer runs only once?

Configuration: DIR9001 as reciever of optical sound and convertor to I2SSTM32F407VG DISCOVERYSTM32 CUBE IDEAfter setting I2S, I can normally at while loop recieve valid I2S singnal from convertor. After change code to DMA and starting the DMA via con...

I want to use the STM32G474VET6 in a robotic application with 3 motors and a diff GPS. Can I program it in Assembly or do I use C? If the latter is Keil a good compiler?

Need help !!! I want to make 3 delay functions which works guaranteed delay in nanoSecond, microSecond and milliSeconds using Timer.

What i am currently using to achieve my goal.Few Details :1: STM32F103C8 Blue Pill2: CMISS core Library3:Datasheet, Reference Manual and Programming ManualI have attached two files. Which give you some idea that how I want to make These 3 functions. ...

Enabling a PWM kills ability to set state on some GPIOs

I am working with an STM32F777. I need to enable both GPIOs and PWMs (which ones is configured at run time by the application). Right now I'm seeing that some PWMs kill other GPIOs. For example if I turn on a PWM on TIM4 CH3 (PB8), it kills GPIOs on ...

Can not open source input file: No such file or directory

Dear friends,I get a silly error " No such file or directory " in Keil IDE while I've already added the file path to include path directory of the compiler.This error happens only when I add lwIP source files to my project. And what's surprising is ...
