2. This Week’s Agenda
7/7/14 An Intro to the ARM Cortex-M4 7/8/14 An ARM Cortex-M4 Design Example 7/9/14 Understanding the ST32F3 Tool Flow 7/10/14 Build Your Own ARM-based Product! 7/11/14 Tying Up the Loose ARM Ends

3. Course Description
Are you ready to learn how easy it is to use ARM Cortex-M4 MCUs in your designs?
This course will introduce you to the ARM Cortex-M4 architecture and describe the key features of an MCU, the ST Microelectronics STM32F3 that uses the Cortex-M4 for the CPU.
A readily available Discovery Board, the STM32F3DISCOVERY, will be used to learn how to begin designing right away!

4. Todays Goals and Objectives
Understand the many design examples available for the STM32F3 Discovery Kit
Be able to select a design as a starting point for your own design
Be able to modify a simple design and run it thru the STM32F3 tool flow see it run on the board

7. Example Peripheral Design (ADC)
This example describes how to use the ADC1 to convert continuously voltage applied
to a given analog input channel.
Detailed steps of ADC configuration are provided starting from GPIO configuration
to the analog channel configuration without forgetting the ADC calibration procedure.
In this example the ADC1 Channel7(PC1) is used as directly connected to the power supply.
The converted voltage is stored in the ADC1ConvertedVoltage variable.

8. Example Peripheral Design 2 (ADC)
This example describes how to use the ADC1 to convert continuously voltage applied
to a given analog input channel.
Detailed steps of ADC configuration are provided starting from GPIO configuration
to the analog channel configuration without forgetting the ADC calibration procedure.
In this example the ADC1 Channel7(PC1) is used as directly connected to the power supply.
The converted voltage is stored in the ADC1ConvertedVoltage variable.

9. Example Design 3 (ADC)

10. Example Design 4 (ADC)

11. Example Peripheral Design (EXTI)
This example shows how to configure external interrupt lines.
In this example, 1 EXTI line (EXTI0) when using the STM32F3-Discovery is configured
to generate an interrupt on each rising edge. In the interrupt routine leds
connected to a specific GPIO pin is toggled.
In this example
- EXTI0 is mapped to PA0.
- when rising edge is detected on EXTI0 by pressing User button, LED3, LED6, LED7
and LED10 toggle.

12. Example Peripheral Design 2 (EXTI)
This example shows how to configure external interrupt lines.
In this example, 1 EXTI line (EXTI0) when using the STM32F3-Discovery is configured
to generate an interrupt on each rising edge. In the interrupt routine leds
connected to a specific GPIO pin is toggled.
In this example
- EXTI0 is mapped to PA0.
- when rising edge is detected on EXTI0 by pressing User button, LED3, LED6, LED7
and LED10 toggle.
