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.

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.
