variable = Count(channel)
|variable||Variable to store results. (No String or Single)|
|channel||Counter channel number (0 to 1)|
Return the counted value from the specified counter channel. Please set the counter's input pins to input before use of this command (refer to the pin/port table for the appropriate CUBLOC module). The maximum pulse frequency is 50KHz.
The CUBLOC’s counter is hardware driven, meaning it runs independently from the main program. It is able to count reliably in real-time regardless of how busy the CUBLOC processor is.
The CUBLOC has 2 x 32 bit counter inputs. Counter channel 0 uses the same
resources as PWM0 through PWM2, so you cannot use both at the same
time. However, counter channel 1 can be used while PWM channel 0 is
Set Count0 On command must be executed before using
counter channel 0. Counter channel 1 requires no additional settings.
For MSB products, the high speed counter pins are already configured as
Input, so it is not necessary to add the
Input xx statements.

As illustrated below, counter 0 uses the same resources as PWM0 through PWM2, so please be careful not to use both at the same time.
