Using 2 boards as a 4 channel/synchronising triggers
Posted: Wed Mar 07, 2018 3:51 pm
Hi. I have a project where I'm going to use 2 boards "nailed" together mechanically to take readings of 4 different signals on the 2x 2x IN signals (hope that makes sense). As the signals will all be related, I would like to be able to synchronise the triggers so that the 2 boards trigger off the same input event, where the input event relates to a real world analogue input I am seeing.
Is there a way using the browser supplied apps I can achieve this? I can wire into the external triggers on the E1 connectors, but what I can't do is use a common signal generator onto the 2 external triggers to trigger at regular times on both boards. It could be of the form "is trigger condition met? If yes then set DIOn high" where DIOn would then be wired into the second board's external trigger pin. The issue here is that I don't really have the time to get a code environment up and running to control the GPIO and as this is taking measurements underwater I won't be able to change anything on the board once the readings are going (it won't be getting wet, don't worry!)
Thanks in advance.
