Hello, I'm having some strange voltage issues from my dual powered programmer. As per the tests in the forum:
vpp-26.6, 32.1, 45.7, 54.1
vcc-10.1
All pins have 8.6 except for following:
27-5.9
22-7.7
13,14,15,17,18,19,20,21,24,25,29 all have 0
The programmer is messing up my bins when programming, I'm always getting verify error with the chip not matching the buffer.
Any idea what is going on here?
Thanks, Dan |

If the voltage is that high, then the programmer is broken. Do not program any chip.
Make sure your voltage meter is working correctly.
Use USB power only and test again. |

My multimeter is working and those values were with usb power only. Will the chips I tried programming still be good?
Thanks for the reply, Dan |

Those chip should be fine. But it to be confirmed with a good working programmer.
