 Now we are moving to configuration tab. This is the third tab and Here we have some deeper configuration of the STM32 In case that you can see I not select any any payfile. I have here also the default clocks Then I have here only three default system payfiles. One is the RCC then reset and clock control The NVIC, the Nasdaq vector in the app controller and the DMA in the DMA controller Which I can use without any IP Activated they are always present Okay in RCC we have some basic settings mainly related to the voltage In case that I change the voltage then it's also sometimes necessary to check the related Payfiles like the instruction and the data cache or the payfile buffer and also to set the call correct flash flash latency Here is not visible on the default default clocks, but in case that I hear change the clocks to the maximum Here need to confirm to change the clock source If I change the clocks to the maximum you can see that here are automatically configured the flash latency In case that I here put the voltage for example 1.8 volt You can see on this is not possible to run the payfile buffer and also my flash latency was changed In case that I put it back Then I change the correct number of the weight states This is important in case that you are not running on the 3.3 volt on our new clock it We always running from the 3.3 then we will not change this parameter And also here is possible to change the power Paravoltage scale to the case or increase the consumption Increase the performance of the of the regulator Additionally in the each configuration tab it's possible to define your own constants For example in case that I want here to have the constant which remind me the HSI Clock then I put here The name and the value will be I think here the 16 megahertz Then I can define this this constant and this will be also generated into my project and then I can use this constant This is common for all the profiles which we which we have in the configuration tab Then you can use it as as you want to to define your own Constants and Last part here is also here is possible to enable the interrupt from the from the RCC Yes, only one is the RCC global interrupt min is used when we for example switching the clocks to Notify the user that the second clock are ready and we can switch on them that now for our examples We will not use the interrupts here This is everything for this configuration The second basic System per IP which we can set here is the vector controller It's also common for the all STM32. You can see that we have one active active Interrupt which is the cystic timer Cystic time is used with in our library to keep the one millisecond time base mainly used for the delays You can see we have no other other interrupts enabled And also you can see we can we can set the pension and the subparity for each interrupt in case that you have the defend microcontroller then m m4 Mainly m0 then you don't have the sub parities above the parities and sub parities We will talk we will be talking a little bit a little bit later during our hands-on Then when we will try to work with the interrupts We will we can also do some hands-on with the changing the parities then don't worry and The last periphery which is always present here is the DMA because we can use also the DMA for the memory to memory transfer We can use the DMA to transfer data from the different related peripherals like you said But we can also use the DMA to create memory to memory transfer about this We will talk a little bit later You can see that here is also a lot of empty space But in case that we enable the periphery for example in the pinout I can enable the additional periphery the SPI In case that we return here you can see now we have here also available the SPI We have also the GPOS because the SPI using here the GPOS They are also related Then we open the SPI and you can see you can set the PESC killer for the SPI Again the PESC killer It's count from the base frequency here from the clock 3 from the APB1 or the APB2 birch and you can deeper configure the SPI about this we will talk a little bit later when we will be working with the SPI And the peripherals more deeply, but for this we need also the knowledge about about the library that this will be not for for now and We will talk about this a little bit later then here in this tab you can find Some deeper configuration of each IP which we have Also some IPs which are not related To the to the pinout, it's also possible to enable here on the left side for example the CRC Can be also enabled here if we go inside you can see there is no parameter to configure In case that we enable the watchdog You can see we can set the parameters of the watchdog the counter the window value Then are some deeper configuration of the IPs which are not related to the pinout Okay, this is all from this tab. We will use this tab many time during the next hands-on stand don't worry
