That is an awesome looking animation and first time I have seen this tiny Oled, great tutorial....cheers !

[@upir_upir]

Many thanks for your nice comment! This display is definitely on my list of displays to use for a next project.

[@NavySturmGewehr]

Thank you so much for these videos. I want to make a custom gauge set for my truck with a 256 x 64 pixel oled. You've really inspired me!

[@upir_upir]

You are welcome, thank you for your nice comment. Do you have any designs that you might share? I would be very interested in seeing it. Thank you!

[@NavySturmGewehr]

@@upir_upir Do you have discord or anything? I did the most important part first... my emblem has been monochromed and reduced to bits! I haven't committed any of the gauge designs yet... I haven't quite figured out how I want to lay them out. My truck has series sequential turbos, so I need egt, exhaust gas pressure, turbine bypass valve position, compressor bypass valve position, high pressure and low pressure turbo boost, and high pressure shaft rpm.

Excellent! 👍

This effect is awesome👍 , you should try TTGO T-display it comes with a built-in display with esp32!

[@upir_upir]

Thank you. Yes, I have some TTGO boards with displays and I hope to use them for future projects.

Thanks for always having such awesome videos. You are a wizard 🤯

[@upir_upir]

@Adrellias thank you for your nice comment, but there is no wizardry involved 🙂 hopefully my videos are showing that..

[@Adrellias]

@@upir_upir they do, but your hw coding knowledge is really awesome, and you are really good at teaching. Thanks for sharing

[@buildyear86]

You have many skills. Really nice work. If you are taking requests: i would be very interested to see how to display a graph with x-axis = time (intervals of, say, a minute) and y-axis temperature (in, let's say, Celsius) and to have the graph show the past 1 hour or so of temperature measurements of a sensor. Some sort of a live temperature graph being drawn on the display as time goes by. How would you approach somthing like that?

[@upir_upir]

Thank you for your nice comment. I´m always interested in knowing what others might like to see, and this time I have a good news for you - a graph project is already on my to-do list and I hope to publish it in the next month or so. Stay tuned!

[@buildyear86]

@@upir_upir No thanks! You are really good at this. Switching from and to skills like it's nothing. Respect. About the graph project: could you do this using a 3 volt battery and a small graphic lcd? Something smaller than the nokia 5510 lcd display used before. I think you should really check out Display Visions' graphic lcd display, part number 'EA dogs102'. I think that one is small and runs on low voltage. Otherwise I believe CrystalFontz' small graphic LCD, part nhmber 'CFAG12864T3-NFH' would be another candidate. This latter display is the smaller one of the two. I really want to explore miniaturization and limit to a 3 volt button cell battery. Lokking forward to it!

[@upir_upir]

@buildyear86 thank you for your nice words. Have you seen my previous video using the pixl.is board? That one has a standard LCD screen, and when you are not using the backlight, it should run on cell battery for a long time.. plus it also includes the temperature sensor, and I also believe there is a tutorial for a graph project already. Could that be an option?

[@buildyear86]

I haven't ... I will try to find it. I don't know the title but am sure will see it eventually, binge watching your channel now :) @@upir_upir

You are welcome!

[@mlg779]

Can you make a video on how you would display Can-bus messages form the car? you already have a video where you have the speedometer and RPM .

[@upir_upir]

Yes, that’s on my todo list. I have a test project running, so video should be finished in some reasonable timeframe…

[@karlohorcicka7388]

Can you try some rgb screens such as those 1.3" tft based around st7789?

[@upir_upir]

Yes, that´s already on my todo list.

[@CDE.Hacker]

I know my question is not about this video, but about the TURZX display from a few weeks back. I got the 5 inch Screen and it works okay. But I have and issue, and don't know if is normal. The screen goes blank for a few seconds and then come back on. I have not tried you theme or created any of my own yet, only because I have other obligations right now. Do you think there is an issue with my display? Or is there any tweaks I can do?

[@upir_upir]

Please next time, ask the question in the related video. This way, it might be helpful also for others. I would start with setting the screen to play a video, and connect it to some power source using the USB cable - not the PC, just a powerbank. If you still see a problem, it´s most likely a faulty unit and you should be able to get a replacement. Let me know if it was helpful.

[@slabua]

Have you tried the 72x40px display with Micropython? I am having hard time with the standard SSD1306 driver, the display turns on slowly after 10 long seconds~

[@upir_upir]

That’s strange. I haven’t used it with micropython, but I don’t think there should be any major difference.

[@slabua]

@@upir_upir right? It might be defective then. I'll try running your Arduino code let's see whether it's a driver or hardware problem ✨

[@mfanelongobeni674]

Can we use a U8g2 library on an SPI OLED?

[@upir_upir]

Sure, you can use both the IIC and SPI displays.

[@mfanelongobeni674]

#include #include #include // Define the SPI pins #define OLED_CLK 13 // SPI Clock (SCK) #define OLED_MOSI 11 // SPI Data (MOSI) #define OLED_CS 10 // Chip Select (CS) #define OLED_DC 9 // Data/Command (DC) #define OLED_RESET 8 // Reset (RST) U8G2_SSD1306_128X64_NONAME_F_HW_SPI u8g2(U8G2_R0, /* clock=*/ OLED_CLK, /* data=*/ OLED_MOSI, /* cs=*/ OLED_CS, /* dc=*/ OLED_DC, /* reset=*/ OLED_RESET); OK thanks, can you please help me here because it's giving me an error🙏🙏

[@upir_upir]

@mfanelongobeni674 you don’t define data and clock for HW SPI, only CS, DC and RESET.

[@user-pe6jj4ob1r]

Where do you do animation?

[@upir_upir]

You mean what tools I use for drawing animations? In many of my tutorials, I have used online tool called "piskel", that was very easy to use for small pixel animations.

[@erosionreactions]

awesome work, but i did this with the Tiny Circuits 0.42" Tiny screen and it wont work. Can you help. I also keep getting a error.

[@upir_upir]

Thank you. What microcontroller are you using? The display seems to be the same as the one used in the video.

[@erosionreactions]

I used the Seed Xiao esp32c3 board

[@erosionreactions]

Sometimes though I get a whole bunch of dots scattered across the screen. I keep looking for help but cant find any videos on this screen.

[@erosionreactions]

oh and the error only happens when i use thier library. (Wireling.h). When I use your code thats when the dots appear. @@upir_upir

[@upir_upir]

@@erosionreactions esp32 does not use "PROGMEM", delete this word from the code and it should work. The PROGMEM is only for AVR Arduino chips, but I thought that for other architectures, this word is simply ignored in the code.

[@buildyear86]

How much current does this screen draw ?

[@upir_upir]

It´s OLED screen, so it mainly depends on how many pixels are on/lit. I don´t know exact numbers, but they are definitely small enough to be able to power this with a cell battery for multiple hours.

[@buildyear86]

@@upir_upir ah ok, i see. Yeah makes sense. Would be interesting to know how much current a fully lit screen would draw. However i guess that in practice a graphic reflective or even transflective lcd display (whether or not led lit or backlit, respectively) of a similar size would draw much less current... ?

[@upir_upir]

@buildyear86 that’s correct, those screens would use significantly less power when used without the backlight.

[@buildyear86]

thanks@@upir_upir ! You rock!
