Pulsating outputs
« on: January 27, 2012, 11:50:58 AM »
Iā€™m just setting up and testing a new ModIO V6.3 board per instructions in user guide ModIO_User092.PDF and find one unusual condition. Following the instructions on page 10, Lighting an LED, activating output 3 on port 0, pin 6 all goes as expected. DOut 4 through 7 all respond to the active low, high state by either staying on or off. However, DOut 0 through 3 flash on and off at about 5 / second with the same setup.

I have a pot set up on analog 1 for test that is read and shown with the VB Script Editor with:
 A= Getinput(64)
Print A

I have nothing wired to analog 2 and 3 but when reading them with A=GetInput(65 or 66) they seem to be reading (64). With none of the analogs wired I get a reading of about half (500+-).

This is from the LCD
ModIOtm   SN:0346
H/W:       F   S/W:022F
Id:      6  57600,8,1,N
DAL1H2HpfkGEd ā€“ DEF ā€“

Any thoughts would be appreciated.

Yes, I know this is an old thread.  I was looking for a solution to the problem too, and did solve it.

Modio does this flashing of the signal on purpose for "lamps" and such (although way too fast to be useful).  You can turn it to a solid signal by changing the register.  Look in the manual for FLASH 103 register.

Better yet, look herehttp://www.machsupport.com/forum/index.php/topic,5185.0.html
