Joystick Setup Configuration 🎮

Before to do the configuration on STM32CubeMX take a look of all pin configurations in this table

Joystick Pin	STM32 Board Pin > Pin CubeMX Config	Connection Diagram
VRx	A5 > PC_0
VRy	A4 > PC_1
SW	D2 > PA_10
GND	GND pin of Board

Navigate to the section Analog
Click on ADC1 tab and select the analog pins that you have connected.
Pay attention on select the right value, in this case we have PC_0 , PC_1 respectly situated in :
IN10 and IN11. The next view that you have is like this.
Now we need to set the Channel Configuration for retrieve the data from the two channels
Go in the Configuration tab and click on Parameters Setting
In the ADC_Settings :
Click on Scan Conversion Mode and set “Enabled”
Click on Continuos Conversion Mode and set “Enabled”
In the ADC_Regular_ConversionMode:
Click on Number of conversion and set “2”
In the Rank 1 :
Set channel 10
Set cycles 480 ( the maximum cycle that board support )
In the Rank 2:
Set channel 11
Set the same cycles as we did before 480

In this section we set the two ADC1 channels to DMA in this way:

Goes in the Configuration settings as before and click on DMA Settings
Click on Add and select ADC1
After we select the Mode as Normal and the other parameter as Word as we see in the picture

Configure GPIO pin for joystick button:
- Navigate to the GPIO Configuration tab.
- Set the pin PA_10 as a GPIO input.
- The final configuration look like that

Ensure that the ADC clock is configured correctly in the RCC settings:
- Navigate to the RCC Configuration tab that is situated in “System Core”.
- Set High Speed Clock HSE as “Crystal/Ceramic Resonator”
Clock configuration Tab
- Take a look on the schema and we need to modify:
- In PLL Source MUX select HSE
- In System Clock MUX select HSI and the last value in the HCLK(MHz) select the maximum value that the board support
