Six (really three) problems with this sick script

monsterthews · July 18, 2020, 5:09pm

Good morning!
I want to make a weather station, and I found a code that does most of what I want in a much different way that I want to try. It does a lot more than I wanted, but each thing happens to be on my list. It’s too long to post:

github.com

G6EJD/ESP32-Weather-Forecaster/blob/master/ESP32_WX_FORE_SCROLL_096_SSD1306_01.ino

/* Last udpate: Added enumerated weather types, improved efficiency
 * Last update: 07-Aug-17, with improved forecast rules
 * 
 * ESP32 and BMP180 or BME280 and OLED SH1106 or SSD1306 display Weather Forecaster 
 * Using air pressure changes to predict weather based on an advanced set of forecasting rules.

Solving one of these problems will help me get past a challenge I have with definitions. I’m fresh from Arduino, so there’s been a lot of hand-holding and preprocessing. I need to understand how to define something early enough to keep it around for a whole program.

280

The ‘Const uint’ exceeds my capacity at the moment. I’d really like someone to just give me the answer, and I’ll make sure to learn it soon.

I can encounter no such error. Using a platformio.ini of

[env:heltec_wifi_lora_32_V2]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 115200
monitor_filters = esp32_exception_decoder 
lib_deps = 
    https://github.com/squix78/esp8266-oled-ssd1306
    Adafruit BME280 Library

(libraries added per the comments in the ino and by library finder)

and adding the .ino code as main.cpp while respecting the conversion rules by adding the function prototypes

void msOverlay(OLEDDisplay *display, OLEDDisplayUiState* state);
void drawFrame1(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y);
void drawFrame2(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y);
void drawFrame3(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y);
void drawFrame4(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y);
void drawFrame5(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y);
float read_pressure();
String get_trend_text(float trend);
void ForecastToImgTxt(weather_description wx_text);
weather_description get_forecast_text(float pressure_now, float trend, bool range);
void wx_history_1hr();
void wx_history_3hr();
void update_time_and_data();
bool update_time();
int StartWiFi(const char* ssid, const char* password);

after line 178 of the original sketch, I get a succesful compilation

The 2 “problems” being reported by VSCode are unused variables

Which is indeed correct, p and t are not used. But that isn’t a fatal compilation error.

monsterthews · July 18, 2020, 11:57pm

Ah! I assumed they were in there somewhere.

Thank you!

monsterthews · July 19, 2020, 12:07am

Looking again, I have no idea what you said. I also can’t remember how I got it down to 6 errors.

I have 35 problems. As usual, nothing is declared.

What does ‘after line 178’ mean? I only care if the whole thing compiles, and it’s not working.

Why did you retype those lines?

The only thing I see that’s different is in the .ini file. I’ve been told only to put edited libraries in the lib folder.

I think I’m in worse shape after your help.

Half of the errors:

Seems like most of your errors are coming from your preinstalled library. Maybe it’s corrupted / not up to date?

I’d suggest using the same platformio.ini (albeit with a different board = .. maybe) and use local library dependency management instead of global libraries.

After line 178 as referenced in the above .ino ifle.

As explained above due to the needed .ino -> .cpp conversion to make VSCode happy with full intellisense. Otherwise just leave it as a main.ino file instead of a cpp file.
