示波器的触发功能做的很帅，速度也比较流畅，屏是SSD1963，使用的是STM32F4探索套件
This is my DSO project which will eventually be given to the public under GPL licence. This is just a glimpse of what is to come.
I accept that this project is my greatest challenge because at the current stage i am lacking lots of knowledge needed to complete
this project. This project started a month ago and has already reached the point where basic dso functions are possible. The video
quality is not the best and i apologise. Many thanks to ChibiOS and especially uGFX for their help which were used to make this project
possible. There will be a dedicated website in a few weeks time that will give more information.
What i really wanted to see in this meter is waveforms of whatever is being measured (except of course DC). I literally want to actually
see what i am measuring in the big high res tft lcd. This meter will be both portable and AC plugable and later connectable to any PC
through an app developped both for Win and Linux platforms.
I know, this is too much!
The target features at the moment are:
- 3 ADC channels:
1 x 24bit 4Msps mostly for low frequency but high precission multimeter like measurements of V, A, R
2 x 16bit greater than 200Msps for high freq content
- Both non-repetitive and repetitive signals
- Power analyser (W/VA/PF etc) for up to 100KHz with integrated current transformers (2 channels to compare with each other - will
use the 24bit adc to capture) and optional external Rogowski coils (1 channel 3 phase capable - will use the 24bit adc to capture)
displaying both HV and A waveforms (cool) and including extended (days) logger of consumptions.
- LC high precission meter.
- (Later) Logger of V, A, R, Temperature, Lux, Pressure and virtually every single type of sensor out there.
