视频和培训

Learn how to configure and use Universal Asynchronous Receiver/Transmitter (UART) communication on the RA8E1 Prototyping Board (FPB‑RA8E1) Arm^® Cortex^®‑M85 entry‑line MCU. The UART peripheral is configured using the Flexible Software Package (FSP), including communication parameter configuration and the implementation of transmit and receive functionality. Data is exchanged between the board and a host system through a serial terminal, allowing users to observe and verify communication in real time.

Learn how to use the real‑time clock (RTC) module on the RA8E1 fast prototyping board to track and display the current time. We configure the RTC in the flexible software package (FSP), including selecting the low‑speed on‑chip oscillator (LOCO) as the clock source. The project demonstrates how to set the initial date and time through user input and retrieve the RTC calendar values during runtime. The application continuously reads and displays the current time at regular intervals using the SEGGER RTT Viewer, showcasing how the RTC maintains accurate timekeeping.

Learn how to configure a general-purpose timer (GPT) to generate a pulse width modulation (PWM) output on the RA8E1 Fast Prototyping Board. We demonstrate how duty cycle adjustment controls LED brightness during runtime. This project shows how PWM enables efficient signal control for common embedded applications.

Learn how to set up an external interrupt on the RA8E1 Fast Prototyping Board. We configure the Interrupt Controller Unit (ICU) in the Flexible Software Package (FSP) to detect input from the onboard user switch and assign the switch as the interrupt source. When the switch is pressed, the interrupt is triggered and the LED state is updated accordingly. This content supports evaluation of basic interrupt handling and helps accelerate development of RA8E1 applications.

Learn how you can create, build, and debug the default blinky project on the RA8E1 Fast Prototyping Board. The board includes two user LEDs connected to pins P404 and P408, which are configured as output pins in the default project. This content supports evaluating basic GPIO operations and accelerates the development of RA8E1 applications.

Take the guesswork out of your innovation experience by following a systematic and methodical approach to start developing with Renesas Advanced microcontrollers kits. It allows for a structured and orderly exploration of resources that you can utilize to create smart IoT and embedded products.

Introduction to the evaluation kits for the Renesas Advanced Microcontrollers. Select from an assortment of ecosystem-ready kits to jumpstart developing your next embedded systems or IoT design. All the kits feature serial connectivity on-board debugging interface and provide unhindered native access to all MCU IO pins.
