Reading From an Output Pin
In the hardware design (PSoC Creator 3.3, PSoC 4 Prototyping Kit) I use some digital components with external inputs to decide how to set a digital output with hardware connection outside the PSoC. This works quite good. Now I want to read this output and use the value in the c-program to display additional stuff on the LCD-Display. But I have no luck in getting a value from the output-pin.
I start with defining a variable...
int CutOffVariable = 1
and later I'm polling the digital output "Cut_Off" with...
CutOffVariable = Cut_Off_Read();
but the variable doesn't change although I measure that the the hardware pin has changed it's status.
I tried also with ...
CutOffVariable = Cut_Off_ReadDataReg()
but I had no luck, probably don't understand the format of the returned value.
Any ideas how to solve this problem?
