I've got a strange problem that probably has an easy solution, but I've been trying to hard to figure it out and am afraid that now I'm missing the obvious.

|

Tried what you said Joshua, I went through all the analog ports and manually fed them with a TTL signal from a function generator at a relatively low frequency of 5Hz and wrote this little test code to test it. In this example, the sencdr3.icb has (...) (25 years ago, 23-Oct-99, to lugnet.robotics.handyboard)

| | Re: Analog port shaft encoder
|
|
Rob, Another suggestion for debuging your setup would be to write a program which; 1, anually counts the pulses from the encoder, and writes them to the lcd screen; or 2, Just writes the state of the encoder input to the screen (a 1 or 0). Then you (...) (25 years ago, 23-Oct-99, to lugnet.robotics.handyboard)

Hi, I am having great difficulty trying to get my shaft encoder to work using both sencdr3.icb or fencdr3.icb driver. I am using the QRB1114 optical sensor connected to analog port 3 with a current limiting resistor of 330 ohms for the emmiter and (...) (25 years ago, 22-Oct-99, to lugnet.robotics.handyboard)

THis may be a dumb question on my part, but we are getting stack overflows on for loops such as for(int i = 0;i<1000;i++){...} when using values over 100 or so. Is this an 8bit counter thing or something else? Thanks, Owen Popplestone (25 years ago, 20-Oct-99, to lugnet.robotics.handyboard)
