I can't believe how important you have become to me. The videos are always 150% more than what I can understand. but, I know you are using all the tools to allow me to follow and put my new knowledge into my own projects. I have a very simple form of this and struggled to get that going. putting the Value of the encoder into a string seemed so simple for you. Thank you so much for taking the time to get these videos up and out others like me.

Thank you for your nice words, I´m glad you like my videos and that you are learning something new and valuable. I´m sure with time, that 150% number will decrease. Good luck with your projects and thanks again!

For remapping the scale on the x-axis, a sin or cos could have been used to create a "rounder" looking stretch effect, I think :)

@upir_upir 4 месяца назад

That´s right, but you cannot change the appearance too much. With the power function, you can play with the exponent and get the look you like the most.

@ithaca2076 4 месяца назад

true but the compute power needed to do that might be a bit overkill especially on projects that are performing extra calculations outside of using the display

@rikilshah 4 месяца назад

Nice idea! We can go with the lookup table!

@theagileaardvark 4 месяца назад

@@ithaca2076 In this case you might want to do it with a sin lookup table (like we did in the old days). Store an array of sin values you would need for half your display and use mirrored values for the other half. No computation needed at all (so from a computational expense point of view even cheaper than the original pow() version), at the expense of a bit of storage space.

Refer to the Maclaurin expansion of cos(x), then you may understand why the auther uses x=y^2 ;-)

Hi, great project and I like the display with the virtual 3D ring. If i am correct the potmeter drives the compass to demonstrate the 3D compass heading ring. Would be great if you could connect a magnetic compass sensor and turn it it in a real compass. Possibly with calibration option.

@upir_upir 3 месяца назад

Yes, correct, it´s just a simulation for now. And I do plan to connect it to the real compass module and try it that way as well.

@SMO_KWEED 4 месяца назад

That's an awesome tutorial! But ever since I discovered your channel I was wondering why are you using u8g2 library and not adafruit one?

@upir_upir 4 месяца назад

Thank you for your nice comment. The library has more fonts, more functions and it supports more displays, but there is not much difference between adafruit one when it comes to those "standard" OLED displays. I have actually used Adafruit library in a few videos as well. Once you learn how to use u8g2, the adafruit library is almost identical.

@janbuck90 4 месяца назад

This is a great project! Is there a way to eliminate the degree value jumping when the potentiometer is not moving?

@upir_upir 4 месяца назад

There are many ways, depends on what kind of problems you see. A simple solution would be to smoothly jump to the next value by adding only a fraction of the new value to the old value. I.e. new_value = old_value + ((new_value - old_value) / 2)

@fredericfitaire2073 4 месяца назад

Nice project ! But I'd prefer seeing it using a rotary encoder instead of a potentiometer for a continuous rotation without stops. An update would be much appreciated ! Thanks

@upir_upir 4 месяца назад

Great suggestion! I´m using a potentiometer because of its simplicity, but I will indeed include some rotary encoders in my future projects. If you need some examples in the meantime, WOKWI has a support for rotary encoder with some examples.

@fredericfitaire2073 4 месяца назад

@@upir_upir Thanks a lot ! An idea would be to increment the compass of 5° for each step of the rotary encoder (or any other value in the code). Looking forward to see it soon ;)

@putraadriansyah8082 4 месяца назад

Hey, can you make a video on how can I generate a signal that varies from 1hz to 1054hz, to run a car speedometer. I have a spare 1988 Toyota Cressida digital cluster that I'm currently experimenting with, i found that the car uses old style spinning wire from transmission to the back of the cluster, and from there it digitalizes the signal using a Optical interruptor sensor. The sensor loves to stop working mid driving just because a small dust. And I'm getting tired to disassemble the cluster over and over again just to clean the dust. So my idea is to use GPS module with Arduino to get vehicle speed, and then pass the signal to the cluster by connecting a digital/pwm pin to the sensor's signal wire. The original sensor is using 5v so it's compatible with Arduino. I've tried using tone(9,100); and the speedometer responds OK, but tone() cannot generate under 31hz (under 9km/h) so it just jumps between 50kph to 299kph if my code applies less than 31hz frequency to the tone() function

@upir_upir 4 месяца назад

Try searching for "arduino pwm frequency library". The library allows for a frequency range from 1Hz - 2MHz on 16 bit timers and 31Hz - 2 MHz on 8 bit timers. Hope that helps!

@lohikarhu734 Месяц назад

i was thinking that it should be possible to do the scaling of the direction characters mathematically, if i use stm32, that have floating point math, and use a trigonometric function to "scrunch the characters as they 'rotate'...seem like a possibility? certainly, the 'canned' pixel blocks work fine, just trying to complicate things 😁

@upir_upir Месяц назад

You can definitely scale images in the code. I have tried that but the result was slow and not quite convincing. The speed should not be a problem on STM32, but I have found it easier to use images since I can tweak pixels here and there if I need to. Good luck with your projects!

@diversitynone431 4 месяца назад

What is the accuracy of azimuth measurement?

@upir_upir 4 месяца назад

Depends on the used compass module, this tutorial is only about the graphics and OLED. From a quick googling, most Arduino-compatible compass modules will give you at least 5° precision, all the way up to 2°. Still not too much.

Хоть польза от максимальной локализации переменных не особо видна в игрушечном проекте из 50 строк кода, эти compass_degrees, buffer, xpos_offset можно было бы объявить внутри функции loop(). Даже переменные, что должны сохранять состояние между вызовами, тоже можно объявлять внутри, как статические. А то, так можно дооптимизироваться до того, что и переменные циклов начать объявлять снаружи функций.
