Linear camera

The Linear camera driver is suitable for 128x1 cameras. It sends the clock and shutter signals to the camera and stores the analog values in an array.

Note: The driver does not provide a function to get the values. Instead, you should declare the buffer as an extern variable like in the example to get the values directly from the driver.

Initialization

void LinearCameraInit(Pwm_ChannelType ClkPwmChannel, Gpt_ChannelType ShutterGptChannel, Adc_GroupType InputAdcGroup, Dio_ChannelType ShutterDioChannel);

Parameters:

· ClkPwmChannel: The Pwm channel configured for the camera in the Peripherals tool.

· ShutterPwmChannel: The Pwm channel configured for the camera in the Peripherals tool.

· InputAdcGroup: The Adc Group configured for the camera in the Peripherals tool.

Getting a frame

void LinearCameraGetFrame(LinearCameraFrame *Frame);

Parameter:

· Frame: The address of the variable where to store the analog values. The buffer must be declared by the user.
