Cautions

1. LED Safety: Do not look directly into the LED beam, especially the high-power LEDs.
2. Power Supply Limit: The E1 On-Chip debugger provides a maximum current of 200mA. An external power supply may be required for full functionality.
3. Motor Control Power: When connecting an external power supply to the motor control part (CN2), ensure jumpers are set correctly as described in section "4.2.1.1 Power supply configuration".

Framework Description

Renesas provides a software framework for its Starter Kits, enabling easy access to controller modules. The kits feature peripherals like encoders, potentiometers, LEDs, displays, CAN, LIN, UART/USB transceivers, and buttons. The framework includes software functions for simplified module usage.

The framework is structured in three layers:

• Application Layer: Contains the actual application (e.g., sample application using lower layers for display, LEDs, and transceivers).
• Modules Layer: Includes modules like `canfd`, which access peripheral functions (e.g., RS-CANFD, port) and potentially controller-agnostic modules (e.g., "led" using port, timer, pwmd).
• Peripherals Layer: Contains source code for microcontroller peripherals (e.g., port functions in `r_port.c`).

Higher layers should only access lower layers.

Sample Software Classic

The software includes a test function and two run modes. Connect the starter kit via USB to a computer for live documentation.

Note: Use a USB 1.0/2.0 Type A to mini USB 1.0/2.0 mini-B cable and a baud-rate of 9600 Bd.

Figure 7. Software flow: This diagram illustrates the software flow starting from Device Reset, through Startup Test, Mode 1, Mode 2, and DeepStop, with transitions between modes and a reset option.

The default software depends on the starter kit version (with or without motor control). Motor control software is detailed in the "Motor Control Application Note".

Start Up Test

Upon startup, the clock is initialized, followed by a start-up test. This test cycles LEDs, sweeps the RGB LED through colors, and checks serial interfaces (CAN, LIN) and RGB LED PWM feedback. Results are displayed via debugger and UART/USB. A test picture is shown on the display before proceeding to Mode 1.

Mode 1

LED1 and LED2 intensity varies with POT1 position, controlling LED duty cycles. Blue LEDs follow the Rotary Encoder (ENC1). The Rotary Encoder Pushbutton changes the RGB LED color. Load current for RGB LEDs is monitored for faults. A short push on S1 switches to Mode 2; holding it for 3s or more enters DeepSTOP. The microcontroller enters DeepSTOP automatically after 30s of inactivity. Mode 1 operates on a 1ms cycle via the Operating System Timer.

Mode 2

LED1 and LED2 blink alternately, and Blue LEDs circle the Rotary Encoder at a frequency determined by POT1. Each interval adjusts LED duty cycles for blinking patterns. The number of circling blue LEDs can be changed with ENC1. Load current monitoring is similar to Mode 1. Switching to Mode 1 restarts PWM output and diagnostics. A short push on S1 switches to Mode 1; holding it for 3s or more enters DeepSTOP. The microcontroller enters DeepSTOP automatically after 30s of inactivity. Mode 2 operates on a 1ms cycle via the Operating System Timer.

StandBy

Entering standby mode turns off unnecessary functions and switches the controller to DeepSTOP for low power. This is indicated by a 2s interval of LED2. Wake-up can be triggered by S1, the Rotary Encoder Pushbutton, DIP switch S6, or POT1 adjustment. Wake-up events are generated by the Low Power Sampler. Resuming returns to the previous mode.

Motor Control Software Example (with display)

If equipped with a Motor Control Unit, the starter kit defaults to motor control FOC example software, detailed in the "Motor Control Application Note". After startup tests, the motor control mode is entered. The board can control the connected motor "stand-alone". The encoder controls rotation speed (clockwise/counterclockwise), with Blue LEDs indicating RPM feedback (500 RPM per LED, -8000 to 8000 RPM). POT1 adjusts acceleration/deceleration (~0 to ~10000 RPM/sec). The software uses sensorless field oriented control with flux estimation.

A PC application, included in the starter kit package, provides more information and allows modification of motor control parameters.

Display Description

The display shows key motor control parameters:

Note: Detailed motor control parameter descriptions are in the "Motor Control Application Note".

The motor control unit supports connecting hall sensors for the delivered motor, though they are imprecise for field oriented control. Custom software can use hall sensors for trapezoidal control.
