I find that the P0 pins are all zero (while it says the reset value should be high = +5V).
both what you measure and what "it says" is correct. your are trying to walk before you can crawl read "the bible", without knowing what's in it you WILL be lost, Erik here are the links to "the bible" Chapter 1 http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf chapter 2 http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf chapter 3 http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf |
