The CH32 only has 64 kB
The attached test fw should fit with 64 kB, totally untested

Hi,

Firstly, thank you for creating this code. It's brought my DSO back to life, a huge improvement over the stock firmware.

I managed to compile the git code to a bin, but there's an error in /src/dso_debug.h as far as I can tell. There's a trailing "²" on line 7. The code then compiles but when flashed the device just has a white screen. I'm compiling with "cmake -DMCU_SPEED=128000000 -DUSE_VANILLA_HW=True".

Can you help?

First of all: think this is an awesome project! I'm really impressed by the work you've done 😄

I was able to install the custom firmware using your compiled (vanilla) binaries and the the open source project stm32flash by running ./stm32flash -b 115200 -v -w Dso150STM32F103_vanilla.bin /dev/ttyUSB0. As this was quite simple, you may consider to include it in your installation instructions.

Secondly, I was wondering whether you intend to get the rotary encoder to work better without hardware mod. Do you think that is possible? Do you intent to implement it?

And more generally speaking: can you say anything about features you plan to add in the future?

i have this error when flashing with st-link v2 on ubuntu 18.04 to my DSO-150

hi i dont find this file. and arduino give me error for this line. how i solved this problem?

It looks like you have a 3d printed case. Did you construct your own device?
I'm looking for replacement Rotary Encoder and was wondering if you had a source?
Thanks

So, I tried both Open DSO 150 and your latest firmware, and both give me a completely white screen, I don't know if the code is just failing or if it's missing a display driver or something.

Is there a way that I can help with information and maybe find out what's the deal with that?

Does the current master code support dumping the input buffer to UART?

Hello,

Finally took the time to install 1.0.6 with rotary encoder mod at 128Mhz.

I am really happy with the firmware so far. I also found some bugs I am reporting below:

1. In 5us mode (10kHz test signal with 1V UP trigger), the selector switches between GND and DC constantly, clearing the selection and preventing to go somewhere else in the UI or to revert to another timescale
2. 10Khz test signal is weird with timescale >1ms (2ms, 5ms, etc...) -> looks like <1khz signal
3. 100Khz test signal is weird with timescale >100uS (200us, etc...) -> looks like <1khz signal
4. Frequency calculation is really off. It is based on one period only ? 100Khz at 10uS varies +/- 25khz.
5. Non working functions :

• Button test = black screen
• Test signal 3V = nothing happens

6. The rotary switch actually requires to be rotated two steps to change a value (might be a hardware limitation?)

Apart from that, I attach a picture so you can use it in the README. For the firmware to be more widely used you have to polish a little bit the "commercial" side and the picture on the main page is not really appealing :)

Hello mean00 and thank you very much for your great work.

Sorry for hijacking the issue page but I could not find any other way to contact you.

I intend to use this firmware on my DSO150. Do you consider the master branch to be stable ? What are the main differences ? Should I go for 1.05 or wait few more weeks instead ? I noticed some changes related to ADC in the last commits.

Kind regards,

Valentin
