Hi there, im working on the development process of a respirator and im using a Riverdi RVT70HSBFWCA0, that has a BT817Q in it.
I've hit a bump in showing live data on the display, im not really sure how to solve and i was hoping to get some help.

To start off, i cant seem to find any widget or tool to display an external value on real time on the screen (Im using EVE Screen Designer 4.8 RC2).
I can show the number of the external value (using numeric label), or at least emulated it, but im finding trouble on displaying it like a continous line on a graph, (kind of like a heartrate monitor).
I tried with the sketch widget and the image widget, tried to mix them with a clock to get a continuous line on a window that refreshes, but i cant seem to get it working.
Has anyone done something similar? Displaying real time changes on a "function" type of display, where X would be time and Y would be the external value im getting trough the STM32?

Thanks in advance, and sorry for any spelling errors, not my native language.

Hello,

Thanks for your question.

Just to clarify you are trying to graph incoming data in a similar manner to the following application note:
AN_356 FT800 Interfacing I2C Sensor to VM800P

When programming EVE at a lower level (not with EVE Screen Designer) we tend to utilise line strips or the line primitive to produce a graph on the screen.

ESD includes a line primitive which could be utilised in a similar way, and you can look at the login patter example for how this renders lines on the screen.

Are you committed to utilising ESD in your projects development? if so, i would suggest updating to the latest available version of ESD 4.15.1.
