Detailed Description

Driver for the I/O Ports peripheral on RA MCUs. This module implements the I/O Port Interface.

Overview

The I/O port pins operate as general I/O port pins, I/O pins for peripheral modules, interrupt input pins, analog I/O, port group function for the ELC, or bus control pins.

Features

The IOPORT HAL module can configure the following pin settings:

Pin direction
Default output state
Pull-up
NMOS/PMOS
Drive strength
Event edge trigger (falling, rising or both)
Whether the pin is to be used as an IRQ pin
Whether the pin is to be used as an analog pin
Peripheral connection

The module also provides the following functionality:

Read/write GPIO pins/ports
Sets event output data
Reads event input data

Configuration

The I/O PORT HAL module must be configured by the user for the desired operation. The operating state of an I/O pin can be set via the RA Configuraton tool. When the project is built a pin configuration file is created. The BSP will automatically configure the MCU IO ports accordingly at startup using the same API functions mentioned in this document.

Build Time Configurations for r_ioport

The following build time configurations are defined in fsp_cfg/r_ioport_cfg.h:

Configuration	Options	Default	Description
Parameter Checking	Default (BSP) Enabled Disabled	Default (BSP)	If selected code for parameter checking is included in the build.

Configurations for System > I/O Port (r_ioport)

This module can be added to the Stacks tab via New Stack > System > I/O Port (r_ioport).

Configuration	Options	Default	Description
Name	Name must be a valid C symbol	g_ioport	Module name.
1st Port ELC Trigger Source	MCU Specific Options		ELC source that will trigger the 1st port
2nd Port ELC Trigger Source	MCU Specific Options		ELC source that will trigger the 2nd port
3rd Port ELC Trigger Source	MCU Specific Options		ELC source that will trigger the 3rd port
4th Port ELC Trigger Source	MCU Specific Options		ELC source that will trigger the 4th port
Pin Configuration Name	Name must be a valid C symbol	g_bsp_pin_cfg	Name for pin configuration structure

Clock Configuration

The I/O PORT HAL module does not require a specific clock configuration.

Pin Configuration

The IOPORT module is used for configuring pins.

Usage Notes

Port Group Function for ELC

Depending on pin configuration, the IOPORT module can perform automatic reads and writes on 4 ports (RA2 series support 2 ports only, see the table of ELC triggers below) on receipt of an ELC event.

ELC triggers	RA6T2	RA2XX	All others
1st Port	Port B	Port 1	Port 1
2nd Port	Port C	Port 2	Port 2
3rd Port	Port D	NA	Port 3
4th Port	Port E	NA	Port 4

When an event is received by a port, the state of the input pins on the port is saved in a hardware register. Simultaneously, the state of output pins on the port is set or cleared based on settings configured by the user. The functions R_IOPORT_PinEventInputRead and R_IOPORT_PortEventInputRead allow reading the last event input state of a pin or port, and event-triggered pin output can be configured through R_IOPORT_PinEventOutputWrite and R_IOPORT_PortEventOutputWrite.

In addition, each pin on these ports can be configured to trigger an ELC event on rising, falling or both edges. This event can be used to activate other modules when the pin changes state.

Note: The number of ELC-aware ports vary across MCUs. Refer to the Hardware User's Manual for your device for more details.

Examples

Basic Example

This is a basic example of minimal use of the IOPORT in an application.

void basic_example ()
{
    bsp_io_level_t readLevel;
    fsp_err_t      err;
    /* Initialize the IOPORT module and configure the pins
     * Note: The default pin configuration name in the RA Configuraton tool is g_bsp_pin_cfg */
    err = R_IOPORT_Open(&g_ioport_ctrl, &g_bsp_pin_cfg);
    /* Handle any errors. This function should be defined by the user. */
    assert(FSP_SUCCESS == err);
    /* Call R_IOPORT_PinsCfg if the configuration was not part of initial configurations made in open */
    err = R_IOPORT_PinsCfg(&g_ioport_ctrl, &g_runtime_pin_cfg);
    assert(FSP_SUCCESS == err);
    /* Set Pin 00 of Port 06 to High */
    err = R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_06_PIN_00, BSP_IO_LEVEL_HIGH);
    assert(FSP_SUCCESS == err);
    /* Read Pin 00 of Port 06*/
    err = R_IOPORT_PinRead(&g_ioport_ctrl, BSP_IO_PORT_06_PIN_00, &readLevel);
    assert(FSP_SUCCESS == err);
}

Blinky Example

This example uses IOPORT to configure and toggle a pin to blink an LED.

void blinky_example ()
{
    fsp_err_t err;
    /* Initialize the IOPORT module and configure the pins */
    err = R_IOPORT_Open(&g_ioport_ctrl, &g_bsp_pin_cfg);
    /* Handle any errors. This function should be defined by the user. */
    assert(FSP_SUCCESS == err);
    /* Configure Pin as output
     * Call the R_IOPORT_PinCfg if the configuration was not part of initial configurations made in open */
    err = R_IOPORT_PinCfg(&g_ioport_ctrl, BSP_IO_PORT_06_PIN_00, IOPORT_CFG_PORT_DIRECTION_OUTPUT);
    assert(FSP_SUCCESS == err);
    bsp_io_level_t level = BSP_IO_LEVEL_LOW;
    while (1)
    {
        /* Determine the next state of the LEDs */
        if (BSP_IO_LEVEL_LOW == level)
        {
            level = BSP_IO_LEVEL_HIGH;
        }
        else
        {
            level = BSP_IO_LEVEL_LOW;
        }
        /* Update LED on RA6M3-PK */
        err = R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_06_PIN_00, level);
        assert(FSP_SUCCESS == err);
        /* Delay */
        R_BSP_SoftwareDelay(100, BSP_DELAY_UNITS_MILLISECONDS); // NOLINT
    }
}

ELC Example

This is an example of using IOPORT with ELC events. The ELC event system allows the captured data to be stored when it occurs and then read back at a later time.

static elc_instance_ctrl_t g_elc_ctrl;
static elc_cfg_t           g_elc_cfg;
void ioport_elc_example ()
{
    bsp_io_level_t eventValue;
    fsp_err_t      err;
    /* Initializes the software and sets the links defined in the control structure. */
    err = R_ELC_Open(&g_elc_ctrl, &g_elc_cfg);
    /* Handle any errors. This function should be defined by the user. */
    assert(FSP_SUCCESS == err);
    /* Create or modify a link between a peripheral function and an event source. */
    err = R_ELC_LinkSet(&g_elc_ctrl, (elc_peripheral_t) ELC_PERIPHERAL_IOPORT2, ELC_EVENT_ELC_SOFTWARE_EVENT_0);
    assert(FSP_SUCCESS == err);
    /* Globally enable event linking in the ELC. */
    err = R_ELC_Enable(&g_elc_ctrl);
    assert(FSP_SUCCESS == err);
    /* Initialize the IOPORT module and configure the pins */
    err = R_IOPORT_Open(&g_ioport_ctrl, &g_bsp_pin_cfg);
    assert(FSP_SUCCESS == err);
    /* Call the R_IOPORT_PinCfg if the configuration was not part of initial configurations made in open */
    err = R_IOPORT_PinCfg(&g_ioport_ctrl, BSP_IO_PORT_02_PIN_00, IOPORT_CFG_PORT_DIRECTION_INPUT);
    assert(FSP_SUCCESS == err);
    /* Generate an event signal through software to the linked peripheral. */
    err = R_ELC_SoftwareEventGenerate(&g_elc_ctrl, ELC_SOFTWARE_EVENT_0);
    assert(FSP_SUCCESS == err);
    /* Read Pin Event Input. The data(BSP_IO_LEVEL_HIGH/ BSP_IO_LEVEL_LOW) from BSP_IO_PORT_02_PIN_00 is read into the
     * EIDR bit */
    err = R_IOPORT_PinEventInputRead(&g_ioport_ctrl, BSP_IO_PORT_02_PIN_00, &eventValue);
    assert(FSP_SUCCESS == err);
}

Return values

FSP_SUCCESS	Pin written to
FSP_ERR_INVALID_ARGUMENT	The pin and/or level not valid
FSP_ERR_NOT_OPEN	The module has not been opene
FSP_ERR_ASSERTION	NULL pointerd

Note: This function is re-entrant for different pins. This function makes use of the PCNTR3 register to atomically modify the level on the specified pin on a port.

◆ R_IOPORT_PortDirectionSet()

fsp_err_t R_IOPORT_PortDirectionSet	(	ioport_ctrl_t *const	p_ctrl,
		bsp_io_port_t	port,
		ioport_size_t	direction_values,
		ioport_size_t	mask
	)

Sets the direction of individual pins on a port. Implements ioport_api_t::portDirectionSet().

Multiple pins on a port can be set to inputs or outputs at once. Each bit in the mask parameter corresponds to a pin on the port. For example, bit 7 corresponds to pin 7, bit 6 to pin 6, and so on. If a bit is set to 1 then the corresponding pin will be changed to an input or an output as specified by the direction values. If a mask bit is set to 0 then the direction of the pin will not be changed.

Return values

FSP_SUCCESS	Port direction updated
FSP_ERR_INVALID_ARGUMENT	The port and/or mask not valid
FSP_ERR_NOT_OPEN	The module has not been opened
FSP_ERR_ASSERTION	NULL pointer
