  1. Thanks! My sampling period is a problem but I tried 50ms before, it didinot work. I will focus on this and try to find the limit of sampling period.
  2. The sampling period is 5ms, is it tio small? and much information will be lost by wifi? I donnotknow how to handle it, so I am still using USB now.
  3. Thx, The attachment is my callback function configuration and I used Step Down Power Supply to power my stack when WIFI extension was used.
  4. Hey, I am building a wheeled driven robot and use WIFI extension to communicate with my laptop, in my callback function I write the velocity of two wheels into files, when USB was use for communication, this callback function works well but when I change it to WIFI extension this program seems didnot get into the callback function at all and there was nothing written in files. Dose anybody know the reason?
  5. I am doing a project about wheel drive robot, I used WIFI extension and the stack was supplied by step down power supply. last week and it worked very well but when i used it yesterday it failed the problem is : 1. when i put the wifi brick on the master brick and connected it to laptop with USB, the master brick cannot be recognized by brick viewer. 2.when i put one DC brick on the master brick, master brick and DC brick were shown on the brick viewer but when I put two DC bricks on the master brick only the mater brick was recognized. It seems to be the problem of supply current but it worked well before until yesterday. Is anybody who knows the reason of this problem, that will be much appreciated. and any discuss about wheel driven robot is welcome. Thanks.
