Yet another fantastic update, thanks!

Do both screens work with either STM32 BluePill or ProMicro?

Thanks 😁

Yes both screens work with both micros. Just uncommented  the micro and the screen you are using from the config tab. 

The BluePill has a lot more memory for bitmaps. The only downside is that neopixels on the STM use the MOSI SPi pin. This being the case I left it out for the moment.

 You can use software SPi and get the pin back but it really impacts the refresh of the screen.

Heya,

Having an odd issue and wondering if I've mucked up somewhere!

I purchased https://www.aliexpress.com/item/0-96-inch-IIC-Serial-Yellow-Blue-OLED-Display-Module-128X64-I2C-SSD1306-12864-LCD-Screen/32896205376.html

When I load the display up, the bottom bit of the screen seems cut off as can be seen in this screenshot:

https://www.dropbox.com/s/68gqtzxcljyv5cr/2019-03-21%2018.10.52.jpg?dl=0

Have I ordered an incorrect display, or is this a configuration setting I can change?

Thanks!

I noticed this issue using the newer adafruit SSD1306 libraries. 

I have never had this issue before in earlier libraries.

Kind of got around it in v1.4 by specifying the pixel height and width

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels

Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

Most vendors just call it a SSD1306 but often they are SH1106. The 1.3" screens are always SH1106 it appears, even though they call them SSD1306

Try selecting the SH1106 library 

Which SH1106 library did you use? I seem to be having compile errors with the choice I have (https://github.com/davidperrenoud/Adafruit_SH1106).

Alternatively, would v1.4 work with my particular setup? I noticed that the power pin option was removed, so didn't want to risk it lest I fried an OLED!

Thanks!

Edit: Ignore - if I RTFM'd, I'd see you already included a link!

All working perfectly with the 1106 library! Thank you very much!

Having a small issue with the neopixel ring... 

I received a ring whch is marked wcmcu-2812B-16, which seems to be a clone of the original, but of a larger size. It works ok-ish, but has 2 issues..

The leds seem to be reversed. The cpu leds are mapped to the bottom part and the gpu leds are at the top.

There's no startup animation (as seen on one of the youtube videos.)

Mostly concerned with reversing the top and bottom mapping. Could you give me  a hint, what needs to be changed in the code?

Thanks!

if you look in the "NeoPixelGauges" tab and take the following as an example

//---------------------- CPU--------------------

void CPU_loadGauge(int cpuUsage ) {

  refreshNeopixels();

  float CPUloadfactor = cpuUsage ;

  if (CPUloadfactor >= 0 ) {
    pixels.setPixelColor( number of the pixel you want to be lit  round the ring, 229, 193, 0);

..............................

if you have 16 pixels the numbers start at 0 -15 , so the first pixel is address "0"

In your case the PCB is laid out in reverse. You will have to go down the "NeoPixelGauges" tab and change all the numbers.

Example: CPU_loadGauge

  pixels.setPixelColor( 15, 229, 193, 0);

  pixels.setPixelColor( 14, 230, 165, 1);

  pixels.setPixelColor( 13, 232, 137, 2);

Above becomes 

   pixels.setPixelColor( 0, 229, 193, 0);

   pixels.setPixelColor( 1, 230, 165, 1);

   pixels.setPixelColor( 2, 232, 137, 2);

and so on..................

Hope this is as clear as mud :)

Thanks man, will dive into it ;)

Thanks for the fantastic project.

I recreated the project, using an arduini nano instead. V1.2 works somewhat ok, but with the v1.31 the telemetry data is not pulled. Is there anything in the latest code, which possible conflicts with the arduino nano?

Replaced Arduino nano with Arduino ProMicro and all the issues gone.

The code needs hardware USB to function correctly

Hi Rupert, thanks for your proyect i'd love it, I'm trying use your gnat-serial-monitor, and detects usage. and temps, but I want send more data like vram, voltage, cpu & gpu freq...so how I can add these parameters?? hope you can help me.

Hi Rupert! I've been looking for a project like yours for a long time. So thanks a lot! But I'm stuck with one meter to go, can you help me out? Everything works great, but the data is missing: no temp, no hardware names, just CPU...blank, GPU...blank, hertz...blank. I've an i7-7700 and a GTX 1080. Hardware Serial Monitor tray v1.1 is up and running. Any suggestions could be very useful to me, thank you!

HI Belean,

Did you run HardwareSerialMonitor as Admin?

Thaks for your answer Rupert! Yes I did. HardwareSerialMonitor_v1.1. And OpenHardwareMonitor v0.8.0-beta works fine, if this can help. You can confirm that if I did everything right it should work even on an updated PC, right? There should be no external variables that could interfere with the project therefore?

if you ran the app as admin and you have selected the correct com port from the tray it should work. The only other things that may effect it are folder permissions, the arduino Com port driver, Antivirus or a firewall blocking the com port.

Hello. Excellent project. I'm trying to reproduce this project, but I'm having the following problem. Can you give me a hand?

how to fix form1 windows problem on serialmonitor?

great project. thanks for share it but i want to same build for my pc. how i set up this parts and how i install to code in arduino? can u help me about this issue?

tell me please,what command do I need to write to display information about the gpu ram load?

Asrul...  Which display have you got ?

hey Rupert, im really new to adruino. im trying to varify the scetch, and i got "splashscreen was not include in this scope" error. How do i fix this? 

Hi,

Did you alter something in the sketch before you verified it? 

Did you download the libraries?

In arduino IDE 1.85 with correct libraries it should complie just fine.

Just because it complains about "splashscreens" does not mean the problem is with that. It could be something as simple as you deleted or  missed out a semicolon somewhere above, in the code.

hi.. i've find out the problem and able to upload the sketch.. but now no display.. can u help me on this.. i ve try as your previous comment below.. but still didnt light up.. any suggestion?

really very happy with this monitor. I will buy WS2812 digital leds right now ;)

OMG ! This is so great !

led is circuit module RGB?

Its a NeoPixel ring with a custom cut overlay.  i would have posted more pics but hackadayio has a limit of 6 pictures.

and on what contacts deduced? amazing thing happened))

Glad to see Gnatstats/HardwareSerialMonitor detects your 8700k Coffee Lake

I saw your CPU on the OLED display on Thingiverse ;)

If you are the same person as below 

" valentin wrote 09/18/2018 at 20:41

I realized a shell in 3D printing from this project:

https://www.thingiverse.com/thing:3107543 "

But maybe i am wrong

this is not me)

it's me ;)

Hi, Thanks for this Project. I am newbie using Arduino, So which one of the libraries do I use ?  I used all of them and when I upload it works but my oled screen doesnt light up. I made sure the pins outs are right.

You have to use all of the libraries mentioned.

You have to uncomment  one of the lines for the perticular OLED display you are using...

//#define OLED_SSD1306
#define OLED_SH1106

or 

#define OLED_SSD1306
//#define OLED_SH1106

If your using a display with a ProMicro on the back as per the pictures 

you will need to uncomment

 //#define enablepowerPins

And uncomment the one below it in the sketch for you perticular screens power requirements.

check you have the correct polarity for the selected OLED screen!!!

Also make sure you i2c address correct in the sketch

for itself decided to use this holder(his own and can convert it) https://ru.aliexpress.com/item/128X64-0-96-O/32871594368.html?spm=a2g0s.9042311.0.0.7a2833edrKLWbw

Hello, very cool project, I would like to ask the question, is it Possible to add a second physical display with the output of information about the state of RAM and paging file?

Yes it is possible but not with the present library. U8GLIB supports multiple screens, It would mean a extensive rewrite of the code.  I am not sure if open hardware monitor supports displaying the page file. 

it's sad, because I was ready to order two displays ((by the way there is an idea about the front panel for the case, if you make it out of black Plexiglas,the display will Shine through and off will also be nice. and please sorry, i use google translate))

I  am working on a enclosure for a variant of GnatStats at the moment :)

GnatStats Release v1.3

Version 1.3: 

Option to trigger an event at a given CPU or GPU threshold eg: LED indicator at 100% CPU Load. 

Top Config option to disable all pre-selected power/gnd pins on Arduino pins D4 and D5 when not powering OLED from ProMicro 

Top Config option to disable/enable "activitychecker" (Enable blank screen on serial timeout eg: PC powered down, Disable to retain last sampled info eg: PC crash or overclocking diagnostics)

NeoPixel Ring CPU/GPU Bargraph example

Thats really great Valentin. I will be sure to link it in the next update :)
