#94652 - Chip not functioning properly |
Hi I am using a AT89LS52 chip and just to see how everything works wrong a program to set P1 high for 1.5 ms and low for 18.5ms. I simulate it with Jsim no problem, but after I program the chip when i test the pin outs they read nothing correct. I have a 4V power source its grounded with a 11.0592 crystal and 2 39pF caps. Im not sure if I am missing anything I went through that data sheet and could not find anything else for such a simple PWM program.
Any advice?? or solutions? Thanks, |
