Firmware 10 on System Red PCB 10.5 - firmware bug ??? - mmlightning - 2024-06-24
Hello,
I installed the new firmware on my PCB 10.5 controller for System red. The PCB was manufactured according to schematic and Eagle-File:https://docs.lightningmaps.org/files/hardware/red/PCB_10_5.brd
The firmware did not work properly as the PCB-ID was not detectected correctly. It turned out that PCB 10.5 has a different coding then described.
Description according to the hardware reference in TablePCB Controller Ids:
https://docs.lightningmaps.org/hardware/lightning-detectors/hardware_reference/#system-red
Id PCB System PD10 PD11 PD3 PD1 Offset
2 10.5 RED - + - - 0
but it turned out that actually Coding of PCB 10.4 and PCB 10.5 is different, PCB10.5 has the following coding:
Id PCB System PD10 PD11 PD3 PD1 Offset
? 10.5 RED + + - - 0
this can also be seen in the schematic of PCB 10.5, so PD10 has a high level +5V instead of GND like PCB 10.4.
I did cut off pin PD10 from the controller-board and now all is working; PCB 10.5 is detected as PCB10.4 now
... but it seems that there is a firmware bug in 10 RED ???? This potentially could affect several stations, as station list has decreased since new firmware is out
