Need help converting mems sound into waves on the stm32f746ng kit

[trinhhoa03]

Please help me everyone.
I'm doing a project about stm32f746ng, they ask me to transmit sound through mems and convert it into waves on a tft screen but I've searched all the documents but still can't find the ioc and sample code. Who can help me? Thank you

Hello @trinhhoa03 

First let me thank you for posting.

Working with STM32 microcontrollers like the STM32F746NG can be challenging, especially when you are tasked with complex projects like transmitting sound through MEMS and displaying it as waves on a TFT screen.

To get started with your project, you can follow these general steps:

1- First you will likely need to understand  the role of  the following components:

1. MEMS Microphone: This will capture sound in the form of electrical signals.
2. ADC (Analog-to-Digital Converter): To convert the analog sound signals from the MEMS into digital signals that can be processed by your  microcontroller STM32F746NG.
3. TFT Screen: To display the sound waves.

2- Refer to the STM32F7 reference manual and datasheet for information on the specific pin mappings and peripheral configurations.

3- Look for example codes or projects that involve ADC reading on the STM32F7 series. These can serve as a good starting point.

4- The STM32CubeIDE is a useful tool for STM32 development that provides code generation and project management features.
