All interrupt pins become input ports when attachInterrupt() is executed. #1
Description
■ Corresponding version
v.1.0.0 and v.1.1.0
■ Contents and Occurrence conditions
The attachInterrupt function is originally a function that sets the specified interrupt pin as an input port and defines an interrupt handler. However, there was a problem in which all interrupt pins were set to input ports in the attachInterrupt function. Therefore, if a specific terminal is set as output before calling the attachInterrupt function, that terminal will be overwritten as input.
The pins to be initialized are as follows
P04, P41, P137
■ Workaround
1. Set the attachInterrupt() function at the beginning of the setup function.
2. After setting 1, Set the next output terminal with pinMode
■ Permanent measures
Fixed in v.1.2.0.
