So my question is :why do I need to divide prescaler by 2 for TIMER 2 and TIMER 3 to get expected period call for my interrupt ? Here's how I set up TIMER 3 : /* Get clock speed */u32_ticks = (HAL_RCC_GetHCLKFreq() /1000000);// = 168pst_TimerHandle->Inst...

Present days, solar technology has been progressing in many applications like homes, industries, etc. The main goal of this project is to conserve the electrical energy:here an Arm-Cortex- based solar street light is implemented that works on solar energy. Generally, solar street lights are used...
