Display Time Block Bug

Post by bungeshea »

I have noticed a bug with the Display Number/Display Time blocks from Team Hassenplug. If you wire a timer into these blocks and place it in a loop, when the timer reaches 33 seconds, instead of displaying 0:33:00 it displays 0:-31:00 and continues counting down in minus until it reaches 0:00:00 and then it starts happening all over again. I have attached a video made with NeXT Screen and Hyper Cam 2, and the test program. Does anyone else experience this bug?

It was not uploading with the message. I do not know if it is an issue of size (2.1MB) or just phpBB. I have uploaded the file to here.

Can't you just use the Capture AVI feature in NXTScreen

Which one are you using.

There are 2 links to the file - who cares what he used to create it?

It does that because the value is a 16-bit signed value. Because time can't be negative, the block should use either an unsigned 16-bit variable (up to ~65,000), or an unsigned 32-bit variable (up to >4,000,000,000).
