 Now, some of the features have also second position, which is not here visible, then, for example, I want on this pins something different, I can check for the alt-A position. The cube mix advise me here to for the alt-A position show use the control and click, Prostežíte kontrolu, kliknám pen, a k tomu hlavní blu je třeba našličit alternativnou pozicí. Přijíte, že alternativnou pozicí na SPI-1 misce je na pb5 penu. A když jsem vzlávat na pb5 misce, můžu přijít pb5 misce. Můžu si vidět, co je výště zvědět, a velmi zvědět. A tady můžu se zvědět SPI do pozíci, jen je velmi zvědět. Ale když jsem vysvědět s pozíci, který je zvědět. Můžu se tady vytvět, kde je zvědět, když se na 17 dneště důvět. Sorry, first I disable the SPI, disable here the pins, enable the SPI again. OK, and in case that I want kupa mix, for example here I have collision between the SPI and also between the ADC, but I know that this SPI have the second RNA position. Then if I uncheck this keep user placement signal, then kupa mix try for me always optimize the pinout and move for example the SPI to the RNA position. Then if I here select the input 7, you can see he automatically moved my SPI signal to the RNA position and I don't need to do this with my own. But in case that you don't want the kupa mix to optimize the pinout for you, you check here the keep user placement and he cannot optimize the pinout for you. OK, I here set my pinout, clear pinout, yes. OK, then this is about pinout. I can here show you some additional functions in case that you for example select one pin as the output. You can with the right click on this pin also select the label when you can put your name because GPO output is not very good explanation of this functionality. Then I can for example here put my let this PA4 will be my let signal. OK. Then here in the pinout menu you can found more interesting functions. For example in case you set the SPI's you set, you can here want you use the three pins for example output, but you want to use for example ten pins not only one which you need to do that you ten times click here and select output which is annoying. Then in the pinout you can here use the functionality set unused GPOs and here you can set how many GPOs you want to set and what will be the functionality in my case for example analog. And he set all unused pin into the output mode. I can again close my pinout. And this is all from this important from this step. Last part I can show you here the USB host how to activate it. He advised me to enable the USB full speed IP. And for example if I here enable the USB for example as a device then here I can use the USB middle wire stack which is related to the USB. Without USB periphery it's not necessary to have USB stack. OK. Then this is all from the pinout. We can jump to the second second part.
