    Enable/disable PCI interrupts. Controlling STM32 Hardware Timers using HAL. The good thing about the timer interrupts is that you actually don’t need to check their status manually. As long as you enable the interrupt by calling HALNVICEnableIRQ, the timer will automatically trigger an interrupt handler function when the event occurs. After you have unzipped the STM32-Discovery-Test-forAtollic you must do: Run ATOLLIC TrueSTDUDIO Lite v.2.1.0 and select the TrueStudio directory. In my case is: C:\ESEMPI-SW\STM32-Examples\Lib340_IO-ADC-UART-SPI_STM32FDiscov-ATOLv210\Project\STM32F10x_StdPeriph_Template\ TrueSTUDIO see below.
