Detailed Description

GainAMP3 Click example.

Description

This example demonstrates the use of GainAMP 3 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration which verifies the communication and sets active the input channel 1.

Application Task

Changes the amplifier gain level every 3 seconds and displays the gain value on the USB UART.

Note

VDDH should be within the range from +5V to +30V. VSSH should be within the range from -5V to -30V. Input channels should be within the range from GND to VCC selected by the VCC_SEL SMD jumpers. Gain * Input voltage must not exceed VCC voltage.

Note

If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
