This view enables the developer to choose between external and internal clock sources. This view is shown in figure 3 and provides a good overview of the clock tree. Clock configuration viewДЄll clock configurations should be done in the clock configuration view. of the SPI peripherals or the sampling rate, data conversion mode, resolution, etc., of the ADCs. It is possible to set the baud rate, data size, endianness, prescaler, clock polarity, etc. In this view, the configuration of the peripherals is done. In addition, it is possible to configure watchdog functionality, DMA transfers, enable the different interrupts and set additional clock and reset behavior. The configuration view shows all the enabled peripherals and middlewarelibraries. More settings related to the peripherals can be chosen in the configuration view. An example of this is FreeRTOS, which is a real-time operating system. The only exception to this is that some middleware libraries can be enabled from this view even though they do not change the pinout. The pinout view lets the developer enable and configure peripherals that affect the pinout. This affects the pinout, but the selected sampling rate, data conversion mode, resolution, etc., does not. Another example is enabling an ADC and ADC channel in the pinout view. In this view, it is not possible to set the baud rate, data size, endianness, prescaler, clock polarity, etc., as they do not affect the pinout. The three possible selections all enables the SPI peripheral, but they also have an effect on which pins are utilized.

For example, one can choose to enable SPI in either full duplex, receive only or transmit only. This view has a focus on pinout and therefore only settings related to each pins possible configuration are set. Both ways of selecting peripherals do not allow a combination that is not supported by the selected microcontroller. Sometimes this automatic conflict resolver might not be wanted and therefore it is possible to lock a peripheral to a pin if necessary. When using the toolbar, it will solve pin conflicts by moving a conflicted peripheral to unused pins that also support the peripheral. The tool will automatically assign the peripheral to the appropriate pins.

Selection of drivers can be made by choosing a pin that support the peripheral directly or by selecting the particular peripheral from the toolbar. It includes a vizualization of the microcontroller and its pins and has a vertical side toolbar.В This is where the required peripherals are selected. Following is a brief explanation of these four views. Configuration of driversДЄfter selecting the correct microcontroller for the application, the user interface has four main views. For getting started quick and easy with prototyping, a board support package and a lot of example project are readily available for the three IDEs: Keil uVision, IAR Embedded Workbench and Atollic TrueStudio. It let the user choose a microcontroller based on the required peripherals, family of microcontrollers, package type, flash size, ram size, minimum number of input/output pins and so on.
