Hal_systick_callback
WebCallback functions are defined as weak functions. My understanding for this is if you define the same function name in your code this function will not be compiled but will use yours instead. For example DMA half-transfer callback in my program. In stm32f3xx_hal_adc.c callback function is defined as: stm32f3xx_hal_adc.c /**
