Esp8266 water flow meter 0.96 OLED screen

hi,
i am new and trying hard to learn.
i have tested my board/OLED with a basic "hello world!" program and that works fine.
i am using the instructions/code from here: "IoT Water Flow Meter using ESP8266 & Water Flow Sensor" and have removed code relating to transmitting to a server as i just want to look at the screen. this is the code:

148 }

i also had to make one change to the remaining code as i could not get it to compile;
when line 34 has the IRAM_ATTR i get this: error: expected initializer before ‘pulseCounter’
void IRAM_ATTR pulseCounter() so i read and it seemed ok to remove it entirely. the other BOLD (so bold does not work in a scroll window- lines removed have ** surrounding them; they are 1, 13-16, 39, 109-147) text was also removed.
i also added the adafruit BusIO library to mine. here is what my library shows:

#include <Wire.h>
#include <SPI.h>

#include <Adafruit_SSD1306.h>
#include <splash.h>

#include <Adafruit_GFX.h>
#include <Adafruit_GrayOLED.h>
#include <Adafruit_SPITFT.h>
#include <Adafruit_SPITFT_Macros.h>
#include <gfxfont.h>

#include <Adafruit_BusIO_Register.h>
#include <Adafruit_I2CDevice.h>
#include <Adafruit_I2CRegister.h>
#include <Adafruit_SPIDevice.h>

when i load it to the board, the screen looks like this:
water flow meter

many people mentioned having trouble with the IRAM_ATTR, but no one said their screen did this.

please let me know what is causing this if possible.
thank you

Hi, have you copy-pasted the code correctly here?

https://arduino-esp8266.readthedocs.io/en/latest/mmu.html

The ESP8266 has a total of 64K of instruction memory, IRAM. This 64K of IRAM is composed of one dedicated 32K block of IRAM and two 16K blocks of IRAM. The last two 16K blocks of IRAM are flexible in the sense that it can be used as a transparent cache for external flash memory. These blocks can either be used for IRAM or an instruction cache for executing code out of flash, ICACHE.

Without going through the code logic, my guess is that the original programmer did not expect someone else to go commenting out sections of code.

I understand you do not want the webserver, but you should first attempt to compile the code as designed and if all sections of code work, then you can start to hack piece-by-piece.

Hi, and thanks.
tepalia02- yes the code is copied straight from his site.
mrburnette- i did try the code complete as he posted it and it gave the same error (in addition to others about missing wifi, etc info) and would not compile
blh64- do u have an idea of what is missing? I searched extensively but can't find what "initializer" should be before the statement.

Thanks to all...

Your posted code contains actual line numbers in the code

After cleaning it up and commenting out the things you mentioned, it compiles just fine for a NodeMCU. As for all those other libraries, you shouldn't include them directly, just Adafruit_FX.h and it will include the others for you...

@everette13,

Your topic was moved to its current location as it is more suitable.

Could you also take a few moments to Learn How To Use The Forum.

It will help you get the best out of the forum in the future.

Thank you

blh64,
sorry i didn't know you meant the numbers. i made a printed copy to include them so i could reference line numbers. they are not actually in the code i put in IDE.

on Tools > include library, under "recommended libraries, i am just clicking on "adafruit GFX library" and "adafruit ssd1306", but in puts all those others in as well. i am obviously doing it wrong- should i be looking in a different location to add those libraries correctly? should i just delete the extra ones?

i put in your cleaned up code (thanks for the time) and deleted the extra libraries. here is what i put in and what happened. it still doesn't compile for me. i tried changing the board to "generic esp8266" and "nodemcu 1.0" and "nodemcu 0.9" versions and get same result.

expected initializer before 'pulseCounter'

and, PerryBebbington, i apologize for the location. i assumed, wrongly, that since the program did not work it would be in the "troubleshooting" section.

It compiles just fine for me as "generic ESP8266"

I see you are using IDE version 1.8.19 - same as me
The ESP8266 boards version I have is 3.0.2

tried again with "generic esp8266" and same result. i don't know what version the board is- when i click "get board info" it says "unknown board, vid: 10c4, pid:ea60, sn: upload any sketch to obtain it" and it says that after loading the "hello world!" sketch.

so, is that it then? it just will not work for me?

thanks for your time

addendum: finally solved- for any of the others in the original coder's site who were having the same problem if you ever make it here, it apparently is caused by the esp8266 library not being up to date in IDE. mine was 2.5.2 (blh64, i thought you meant the actual board was 3.0.2, not the version library installed in IDE) and IDE does not tell you an update is needed. once installed 3.0.2, all works well.
