Re: RTC component in 2d panel

Hi

You can easily rescale it from within the Dashboard. Simply select it, click the rescale icon on toolbar (5th from left) then drag component to desired size.

Hope this helps
Regards

Re: Esp32 with Ili9341 and DS18B20

Hi Jorgen It's just referring to the "x/y" pixel position. "x,0" is the top of the display with your baseline at position x,225. To plot the Temp against this baseline we simply deduct the temperature from 225. If the temperature was 0 then the graph would show a line being drawn at x,225 (225-0). I...

Re: running a DC motor using the arduino motor shield

Hi Try the attached. Do you have a logic analyser or scope? If so look at the output pin on the Uno, it should show a 50/50 square wave. If not perhaps try an led with a resistor in series. It won't flash but if you change duty to 255 it should then be brighter than 128. This will at least prove you...

Re: Esp32 with Ili9341 and DS18B20

Hi Jorgen In the attached I "spun" the display around in 2D Panel to make it easier for me to read. In the DS18B20 Macro I added in a command to set the address I created a new variable called "Plot" and In the Live_x Macro I added a calculation Plot=225-Temp. This then offsets the Temp value with r...

Re: Esp32 with Ili9341 and DS18B20

Hi Jorgen Looks to me that you might have forgotten to set the device address in your DS18B20 macro. Try adding a AddressSpecificDevice ("000000000000") component macro before you sample. I included the above and the calculation mentioned earlier and in simulation I can plot. I'll forward a chart la...

Re: Esp32 with Ili9341 and DS18B20

Hi Jorgen I only had a quick look today. I should get more time tomorrow to look further. It turns out I do already have one of those displays. I ordered up one last year, but as it came with zero documentation it went into the "play later" pile. I've since found a good site that provides help inclu...

Re: Esp32 with Ili9341 and DS18B20

Hi I want one of those displays. Amazon or such like will be my next site :D Not having the chance yet to play with one I can only suggest some things to try. Maybe someone with better knowledge can assist further. In properties it appears to be able to Flip X and Y (in Hardware) but in simulation t...

Re: running a DC motor using the arduino motor shield

Hi Martin

Thanks for the clarification. I'll check the compiler messages later too.

Re: running a DC motor using the arduino motor shield

Hi Working now sort of.... With Duty set to 128 I get the expected 50% Duty Cycle on the analyser. However irrespective of the frequency set under properties, I always get half of expected. If set at 7.8KHz I get 3.9KHz etc. Freely admit to only starting to play with the Uno so maybe I'm doing somet...
