IS31FL3236_WriteLEDControl Function

Declaration

void IS31FL3236_WriteLEDControl(IS31FL3236_HandleTypeDef* handle, uint8_t channel, uint8_t led_current_setting, uint8_t led_state);

Parameters

• handle [IS31FL3236_HandleTypeDef*]: The handle instance of the IS31FL3236 chip.
• channel [uint8_t]: The channel number (0 - 35) to change the PWM value of.
• led_current_setting [uint8_t]: The new LED current setting of the specified channel. Use the definitions IS31FL3236_LED_CURRENT_MAX, IS31FL3236_LED_CURRENT_MAX_DIV_2, IS31FL3236_LED_CURRENT_MAX_DIV_3, IS31FL3236_LED_CURRENT_MAX_DIV_4 to specify the current mode of the channel.
• led_state [uint8_t]: The new LED state of the specified channel. Use the definitions IS31FL3236_LED_STATE_OFF and IS31FL3236_LED_STATE_ON to specify the LED mode.

Description

This function sets the LED current mode and state of a specified channel. Further information about the LED current mode and state can be found in the manufacturer's datasheet of the IS31FL3236 IC. (Link to IS31FL3236 Datasheet)

Example

// Set the LED current mode and state.
IS31FL3236_WriteLEDControl(p_hIS31FL3236, 3, IS31FL3236_LED_CURRENT_MAX_DIV_2, IS31FL3236_LED_STATE_ON);
// Send the chip and update command.
IS31FL3236_Update(p_hIS31FL3236);
