Want a battery saver? 1. In the menu, there would be a choice after which time the backlight level should be reduced and a setting to which level it should be reduced.
1. video is not available
2.exceeding the range of the AD converter
instruction 0.025v
different roll mode, only test, no final solution, try and comment.
Clearing the display and rendering everything takes some time, so I'm not sure if it can even render at 100ms/div
Special thanks for the saved backlight state! About the new display.
1. Channel 2 is not working
2. The scrolling speed for 100 ms, 200 ms and 500 ms is the same from 1 second
3. It would be good to make this mode turn on separately from the button, either as it was before, or scroll mode.
4. Few points are drawn on the ray, there are no lines that connect them into a solid line.
In conclusion. It turned out very cool! That's what I wanted! It remains to refine a little)
This style was not used because it takes a lot of time to erase the entire display and redraw it. Therefore, the sampling frequency is rapidly reduced. The question is whether it could be optimized somehow.
Won't it be possible to organize a fifo type? But even if you do not change anything, this mode can be useful already in this form, only activate it not by default, but as an additional function on the button and if there is not enough power, then do not from 100 msec, but from 1 second.
Because the dc shift is 0.
Hi Atlan
, Regarding our 1013D oscilloscope, could you let me know which firmware version you’d recommend as the most reliable for daily use? Thanks,
Russell
Firmware 0.025u with userguide 0.025v.
It is possible to upload a new version tomorrow, where the overload is fixed so that the signal is red.
v0.025x Saving the brightness setting, correction of exceeding the range of the ad converter - the displayed signal course is red. roll mode old version
PC. Is it possible somewhere in the code to simply turn off the correction function using the value (ADC comp) (why is it done first for adc1(ch1) and then for adc2(ch1). Thanks
A simple turning it off, I don't think so, but I made it like this to get a slightly larger and better centered range. If the compensation is only done on one ADC, like in the original, and the difference between the two ADC's is let say 6, you have to add or subtract 6 to or from one of the ADC's, thus limiting the range from 0 to 249. If you split it in the middle and adjsut both ADC's with only half the value the range becomes 0 to 252. It is not much, but in my eyes better.
ok thank you. if the Chinese did not extend the power supply around the uP, fpga, ad converter and so on to the input amplifier... when I extended a separate power supply for each part, the interference is 0-1

Yeah, the hardware design is not the best, but we already knew that.
Unable to measure long term signal
v0.025u
Save the wave, and measure there.

I don't know how to get this menu (300mv and others) again. Because the menu doesn't appear anymore.
Resetting calibration does not help.
Now I tried it, everything works like me. I perform a reset through the diagnostic menu, return to the main menu, start the base calibration, after performing the calibration, a request to connect 300mV is displayed and so on.
How to mirror the touchscreen vertically? gt911
I recommend doing it through the program loader 1.1.3, because the bits for the botloader are also located in the given space (behind the settings of the touch panel and the rotation of the display)
Is it possible to connect a USB serial interface to CH340b based on this? f1c100s_ch340 is it functional? Somehow it doesn't work for me. Where is the baud rate option?
Is it possible to connect a USB serial interface to CH340b based on this? f1c100s_ch340 is it functional? Somehow it doesn't work for me. Where is the baud rate option?
I wrote that code to test the USB interface in device mode. The f1c100s_ch340_sd_package version was used to test communication with the FPGA. It emulates a CH340 USB device on the host, but not on the device itself, so no serial communication from the F1C100s to some other hardware.
It works for sending and receiving data to and from the F1C100s. If you want to use the F1C100s UART in combination with the code I wrote, you have to extend the code.
The link between the host and the device is baud rate independent, and I did not implement any of the control stuff in the handler on the F1C100s.
So it is just a tool for easy communication with the F1C100s.
