Hi, I have bought the Fscope-500K board and the connector H12 for signal generator connected to GP16 but the firmware programmed at pin GP22. Could you or anyone please send me the correct firmware so that the pin output for signal generator is for pin number GP16?

Hi, The firmware for the FSCOPE-500K can be found here: oscilloscope.fhdm.xyz/wiki/firmware-versionsYou'll need either scoppy-fscope-500k-pico-v18.uf2 or scoppy-fscope-500k-picow-v18.uf2 (the one you need to use depends on whether you are connecting a Pico or Pico W to your FSCOPE board). |

Yes I have downloaded and install this firmware. Please check my concern, the signal generator terminal pin (H12) is not connected correctly to the pin of raspberry pi pico. It should be connected to pin GP22 not GP16. You can see also the track on the PCB its clearly connect to pin GP16, the wrong pin.

OK. I suspect the FSCOPE firmware is using the wrong PIN for the signal generator because it is using settings from the previous firmware that was installed. Oops - my bad. If this is the case there are two things you can do: 1. Wipe all data from the flash storage on the Pico by copying flash_nuke.uf2 to it and then reinstall the FSCOPE firmware - flash_nuke.uf2 is available here: datasheets.raspberrypi.com/soft/flash_nuke.uf2Or 2. you can use the 'Restore Defaults' function from the app as follows: - tap the Connection badge at the lower left of the screen (ie. the one that shows USB or WiFi) - tap 'Connected Device' and then 'Firmware Settings' and 'Restore defaults...' - tap OK in the confirmation window - Disconnect and then reconnect power to your Pico If this doesn't help please let me know and I'll investigate further. Sorry for the inconvenience. I'll update the installation instructions ASAP! |

OK thank you so much, its works. Maybe the previous firmware SETTINGS causing this problem. I have installed other scoppy firmware before buy the FSCOPE-500K board.
