lwshyang WROTE:i checked these two capacitors on board only. i have got quite weird value.
for
C5 : 170pf ( when i tune capacitance meter to 200pf range ), reversed polarity i get 1 ( too small)
1200pf (when i tune to 2000pf range), reversed polarity i get 1
C6 : 190pf (when i tune to 200pf range), reversed polarity i get 1
1400pf (when i tune to 2000pf range), reversed polarity i get 1
or can teach me how to on board measure the capacitor correctly? thanks
Thanks for the photos and video, it is very helpful for us to verify any possible problem. Seem to be the capacitor is correct. I asked this because we did get some similar cases where the board keep resetting itself and finally realize that user connect wrong capacitor at crystal. Is difficult to measure capacitance when the component is on board. That is should be fine.
Looking at the video you posted, again thanks for the effort, seem to be it is drawing too much of current at a moment and reset. After reset the current draw drop and the voltage back to normal and supply to PIC again, and this process repeat. I would suggest you to fill in the form under support tab in our website. Support team might arrange for send back and troubleshooting. That should be faster in solving your problem.
