#13089 - RE: 89c52 need pull up resistor at port 0 ? |
Hi! I agree with Alfredo but I always have been using pull-up resistors for "any case". The value of pull-up resitor depends on you microcontroller's output current and current you really need.
Usually I have been using 8x47k or 8x10k (8 resistors in one package). Jacek |
