Posted 3310 days ago by zarya Getting closer to the issues but no fix yet, it looks like the ADC is having problems if i measure the ADC0 its around 2.4 volt but when i print the value to the serial line its 1023 |

Posted 3320 days ago by zarya It stays low only a reset of the MCU brings back the voltage. |

Posted 3321 days ago by zarya C9 is 2 68pF 500v caps in series to make around 22pf still waiting for the 22pf C's to be delivered. The tube seems fine when booting after that it stops working and the voltage goes down to 2 volts. The software i am running is also 2.61 btw |

Posted 3321 days ago by zarya I finally got around soldering the kit together Now it does not work i rechecked all the welds, the unit is running without a display There is only 2 to 3 volts on the tube all the 5v rail looks good. It looks like i am missing R19 it was nog soldered BOM said i should be delivered. Serial output only gives ???????? i tried to re-flash the bin file and reset the fuses this all did not help to much After some more fiddeling around i found out that i am unable to set the EFuse to 0xFC avrdude: verification error, first mismatch at byte 0x0000 0xfc != 0x04 please help me |
