I am trying to write a function in c for stm32 board. float computeMotorSpeed(TIM_HandleTypeDef &htimer, uint32_t &PreviousCount ) { int32_t DiffCount = 0; uint32_t CurrentCount = 0; CurrentCount = __HAL_TIM_GET_COUNTER(&htimer); /*evaluate increment of timer counter from previous count*/ if (__HAL_TIM_IS_TIM_COUNTING_DOWN(&htimer)) { /* check for counter underflow */ if (CurrentCount <= PreviousCount) { DiffCount = CurrentCount… Read More fucntion in C++ in CUBEide

I have a code: void core() { loop { first_process(); secound_process(); process_synchronizer(); } some_other_job(); } In the process suynchronizer() I evaluate synchronization and if the criterion has not beeing satisfied it will break the loop. The problem is the break is not allowed in that function since it’s not in the loop. void process_synchronizer() {… Read More How do I break, from outside of a loop in C?

I want to have a simple float to string converter for an embedded project and would like to not use floating-point snprintf as that would really fill my flash, so i wrote a simple conversion function. I don’t really care for an exact number of decimals nor negative values. This is just a C++ example,… Read More Why is my static array not cleared by memset?

I am using CMake for a STM32 project as the project is outgrowing a plain Makefile. My directory structure looks something like what’s below. I have an executable defined in the root CMakeLists.txt and somelib compiled as an OBJECT library which is added to the main CMakeLists.txt using add_subdirectory. CMakeLists.txt src/ ├─ app/ │ ├─… Read More How can I apply target-specific compiler and linker flags to subdirectories in CMake?
