If you modified the rotary encoder you need this firmware : [Dso150STM32F103_usb.bin.zip](https://github.com/mean00/DSO_STM32Duino/files/5902417/Dso150STM32F103_usb.bin.zip) (v1.0.6 @ 72 Mhz)

The frequency meter is not very accurate at high frequency + the 5us/div range is a bit buggy If you can try using 10u/div, it should be better

Not sure i got the point, but The GD32F303 can go up to 120 Mhz, but it's not needed. It has several difference compared to the STM32F103 : - The...

The problem is the bandwidth of the analog parts (opAmp in particular) Increasing the CPU clock will not help It works above 100khz, but the signals get weaker and weaker...

for info this is the latest firmware compiled with the rotary change (better to use the one a few posts below, the calibration bug is fixed) I'm not sure improving...

The master branch is using timers as sample rate instead of duplicating/ dropping samples, which is more accurate. It is slightly less stable than the last release but the timer...

Small warning : master is no longer using a bootloader. That was what was creating crashes at boot sometimes. So if you go back & forth between release and master,...

The main problem is synchronizing the ADC with the digital inputs. The ADC is basically doing things on its own until it is triggered it is difficult to use another...

Interesting ideas, the digital ones could be used as triggers also. I'll look into that later on. Short term wise, I'd like to have a better trigger that what is...

you can try this on head: _cmake -DMCU_SPEED=128000000 xxxxxxxxxxxxx_ Only 72,96 and 128 Mhz are supported Seems to work fine as far as the ADC is concerned on mine
