I would like to program the GP timer of the Blackfin in order to sample the sensor data with a defined frequency. Therefore I would like to ask the following:
1- How can I set the parameters (ADI_TMR_GP_CMD_SET_PERIOD and ADI_TMR_GP_CMD_SET_WIDTH) of my GP timer to trigger a callback every 100Hz. I could not find the formula to set these parameters?
2- what is the difference between these two parameters:
as I understood one is used for the period value of the timer and the other is the width value of the timer.
3- If I would like to configure the GP timer so that it counts up and when it reaches a value it reset and starts again to count up to that specified value. For this configuration what should I fill the parameter (ADI_TMR_GP_CMD_SET_TIMER_MODE)?
4- what is meant by the values of the parameter ADI_TMR_GP_CMD_SET_TIMER_MODE:
