Reading INPUT’s from the IMS C011

After controlling the output of the IMS C011 Transputer IO-Link interface it is now time to take a look at the input’s. Before my friend can build a Robot based on a Transputer system we must can control output’s but also read input’s from sensor’s. So let’s take a look at the Input’s of the IMS C011 Transputer IO-Link interface.

I wrote a little program how i think how it must be work’s.

But nothing happens (ofcourse ?) At saturday 16 March there was an meeting of the HCC!Retro computer club. This means Hobby Computer Club, section Retro computers. This meeting was held in Bilthoven the Netherlands.  HCC!Retro website

During this day we have a lot of talk about Vintage computer systems, core memory, Bubble Memory and other old hobbycomputer stuff. Also we have a little look at the transputer I carryed with me. When I ran the program noting happen, but when a friend of mine take a look at the IO-Interface print I have build he take a look at the backside of the print. On that moment a saw some numbers comming on the screen ??!!

Wait !! What is happening here, then I remember the handshake signal’s. The Ivalid was not connected and this is high impedance so when you are moving your hand in the area “sometime’s” you get a high strobe on the input and then you get a value in your system.

I took a nice little wire and use this as a strobe signal to the +5Volt. When i touch the Ivalid then the value of the dipswitch would be displayed on the screen. Victorie !!!

Next step is to make the system a little bit more better working. I decide to connect the OVaild to the IValid so when i get data for the output, then also the value from the dipswitches goed into the IMS C011 to the Transputer.

Now I read the values of the dipswitch very good.

Lessons I have learned about this: There are 4 handshake line’s on the IMS C011. Think about them carefull !
