What Will I Learn?

• Adding a touch screen to a project on a developet board
• Sending and receiving data from and to the screen using UART
• Using the General Purpose Input Output (GPIO) pins of the screen as Input, Output, and PWM.
• Creating a custom animated gouge (animated battery level indicator)
• Receiving data to screen by creating a battery level indicator using the ADC of the development board and UART communications
• Sending UART data from the screen to the dev. board and from Dev board to a MIDI shield
• The screen used in this board is from Nextion, and the Dev board is Nucleo-64 from ST Microelectronics with 411RE microcontroller

Requirements

• Familiarity with programming in C
• Familiarity with a development board and an IDE software to program it
• If you are no familiar with the above, then it is still an opportunity to understand the concept.

Target audience

• Makers who want to learn hwo to add touch screen to recevie and send data and istructions
• Engineers who want to add a touch screen to their
• Engineering students who want to create touch screen cotrol panels attached to their projects
• Anyoen prototyping and interested in adding screen
