Overview
Le Slider Click Board™ est doté d'un potentiomètre mécanique à glissière - un curseur, qui donne une sensation agréable lors de l'actionnement, ainsi que de 16 LED SMD, qui peuvent être utilisées pour tout type de retour visuel. Le convertisseur analogique-numérique haute résolution 22 bits intégré peut détecter même le plus petit mouvement, capturant fidèlement la fluidité du mouvement du curseur, tout en numérisant sa position. Les 16 LED SMD intégrées peuvent donner un bon retour visuel de la position du curseur, mais ces LED peuvent également être utilisées à d'autres fins car elles ne sont pas câblées au curseur.
Le Slider Click Board™ permet de contrôler diverses applications numériques avec un potentiomètre à curseur précis et confortable, tandis que les LED permettent d'afficher les informations souhaitées sous forme de barre ou de position. Par exemple, le Slider Click Board™ permet de contrôler un potentiomètre numérique quadruple, tel que celui que l'on retrouve sur le DIGIPOT 5 Click Board™, tout en affichant la position du curseur numérique sélectionné sur les LED.

How Does The Slider Click Board™ Work?
The Slider Click Board™ consists of two sections: the first section is the slider section itself, with the sliding potentiometer end terminals connected between GND and the VCC, and the wiper connected to the MCP3551 IC, which is a low-power, single-channel 22-bit delta-sigma ADC from Microchip. The slider acts as a voltage divider so that the voltage between the GND and the wiper position is determined by the slider position. This voltage is then applied to the input pin of the 22bit ADC converter and converted to a digital value. The MCP3551 has its SPI lines routed to the mikroBUS™ so that the values can be read easily by the MCU.
The second section of the Slider Click Board™ consists of the MAX6969, a well know 16-port, constant-current LED driver from Maxim Integrated, used to control the SMD LEDs. The MAX6969 IC uses the same SPI lines as the ADC, but to avoid data collision, different chip select (CS) line is used. While the ADC uses the CS line routed to the CS pin of the mikroBUS™, the LED driver uses the RST line of the mikroBUS™ as the chip select input. This allows to work with both ICs independently. MAX6969 output enable (OE) pin is routed to the AN pin of the mikroBUS™, making it easy to completely turn off the output stage of the MAX6969, by setting this pin to a HIGH logic state. If left floating, this pin will be pulled down to the GND by the 10K resistor. The output LED current is constant and it is set to around 20mA by the resistor on the SET pin of the MAX6969.
The Slider Click Board™ can work with both 3.3V and 5V, depending on the used MCU capabilities. This can be done by switching the VCC SEL SMD jumper to the desired position.
SPECIFICATIONS
| Type | Potentiometer |
| Applications | The Slider Click Board™ can be used to control various digital applications with an accurate and comfortable slider potentiometer, such as the PWM ratio for the lighting, digital volume for the audio amplifiers, BLDC motor speed control and similar. |
| On-board modules | MCP3551 - a single channel 22bit delta-sigma ADC from Microchip, MAX6969 - a 16 segment LED driver from Maxim Integrated |
| Key Features | It features a smooth action slider pot, that can be used to control any digital application. The onboard 22bit ADC allows a very precise and faithful capture of the slider movement. 16 LEDs can be used independently for a visual feedback. |
