 Okay, in previous lectures we talked about the CUBE MX, about the pinouts, about the configuration, what is necessary to install and now it's the time to test our first hands-on and test if everything is installed correctly, also the IDE and test if we can also work with our discovery board, nuclear board or the eval board. Okay, then we start with the new project. I will here select the F4 series, the line F401 and the package LQFP64 and I have the STM32 F401 RE on my nuclear kit. In case you have different processor you need to select the different family, different series, different line. Now my RE, now what I need to do, I want to create a very simple hands-on for the lead toggling. This will be very easy. First I need to select one pin which is dedicated to lead. I know that on my nuclear board it's this pin PA5. Then I can select PA5 as an output which is very simple. Here I can also label my name of my pin. It will be for lead for the better naming. And this is all from this tab. The clock configuration I'm okay with the default setting for the GPO toggling. I don't need to do anything more but I here need to check the configuration in the GPO. I only check the GPO state after configuration will be low. I'm okay. The mode will be push-pull. This is okay in line with my configuration. Now pull-up, pull-down resistor is also correct and minimum speed. The skew of the edges is low for the GPO toggling. I think it's enough and we can save this. We can here save our project. Damn this I need to change here in the trainings. Example projects. Okay this I will cut a little bit later. GPO one for IR. You can name it how you want. I click on the okay. I can generate a project with the project generate or here with the icon generate project. Let's take a while and now the QPMix asking me to open my project in the IR. Then I can click okay and open my project.
