Multifunction Pins
The multi-function pins accept different operational modes. They can be used as Digital Inputs, Digital
Outputs, Interrupts or PWM signals (defined via Software PIN MODE).
MF pins can only operate at 3.3Vdc or 5Vdc (configurable by switch). It is very important to check the
configuration of the switches for the use of the multi-function pins before making the connection to verify
the voltage in which they are configured.
Please check the following table to select the desired signal voltage level:
ATTENTION
Material damage!
Disconnect Weidos from Power Supply before any change on DIP switches configuration.
As described in the last table, only DIP-Switches 1, 2 and 3 from SW1, need to be configured for operational
voltage of multi-function pins selection. If they are all in the ON position, the pins will operate at 3,3 Vdc,
while if all switches are in the OFF position, they will operate at 5 Vdc.
Multifunction pins are located in the following Weidos connector:
