Read Inputs
Read the 8-bit state of all inputs on a 'P1_HSC_Module' variable or read the 4-bit state of the four inputs of a 'P1_HSC_Channel' variable.
Used to read all input state bits (bitmapped in order) of a 'P1_HSC_Module' variable. These blocks return an integer whose bits contain the state of the module's inputs. The value of 'HSC' specifies which module to read, and the value of 'Channel' specifies which channel.
Bit mappings:
Read Inputs (HSC):
| bit | value |
|---|---|
| bit 1 | 1A |
| bit 2 | 1B |
| bit 3 | 1Z |
| bit 4 | 3IN |
| bit 5 | 2A |
| bit 6 | 2B |
| bit 7 | 2Z |
| bit 8 | 4IN |
Read inputs (Channel):
| bit | channel 1 | channel 2 |
|---|---|---|
| bit 1 | 1A | 2A |
| bit 2 | 1B | 2B |
| bit 3 | 1Z | 2Z |
| bit 4 | 3IN | 4IN |
- These blocks may be used independently.
- The second block only reads the state bits of one 'Channel' while the first reads the state bits of both channels.
