what is the drive strength in numbers???
typedef enum CyU3PDriveStrengthState_t
CY_U3P_DS_QUARTER_STRENGTH = 0, /* The drive strength is one-fourth the maximum */
CY_U3P_DS_HALF_STRENGTH, /* The drive strength is half the maximum */
CY_U3P_DS_THREE_QUARTER_STRENGTH, /* The drive strength is three-fourth the maximum */
CY_U3P_DS_FULL_STRENGTH /* The drive strength is the maximum */
How much mA or µA can a GPIO pin drive when it is configured to 1/4; 1/2; 3/4; 1 ???
We are in the process of evaluating the current numbers under different drive strengths.
I will update you soon on this.
I am interesting to get this information also. I'd like to connect optocoupler to GPIO but I have to know current strength ability to drive it.
