Detailed Description

Waveform2 Click example.

Description

This is an example that demonstrates the use of the Waveform 2 Click board.

The demo application is composed of two sections :

Application Init

Initialize the communication interface, preforming hardware reset, and configure the click board.

Application Task

Predefined characters are inputed from the serial port. Depending on the character sent the signal frequency, waveform or amplitude will be changed.

• Command: [ + ] - Increase frequency [ - ] - Decrease frequency [ t ] - Triangle-shaped signal [ s ] - The signal in the form of a sinusoid
• Additional Functions : aprox_freq_calculation( float freqency ) - This function is used to calculate the aproximate value that will be written to the frequency set register.

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.
