And I can't even get the regular EEPROM.read() and EEPROM.write() functions to work when I turn my unsigned long variable into an int. You're right, it does have a different library which seems very bare bones and maybe broken. Ppm = 0.2 * (analogRead(tdsPin)) - 23 //calculate ppm from voltage If (currentMillis - startMillis >= standbyTime & timer = true & count = 0) // timer is running and standby time has passed, count is already resetĮlse if (currentMillis - startMillis >= resetTime & timer = true & standby = false) // timer is running and reset time has passed, not in standby (yet)ĮEPROM.put(0, mlCounter) // write the contents of mlCounter to the EEPROM starting at address 0 time elapsed since last change in volume
StartMillis = millis() // set timer to zero If (ml2 = ml1 & timer = false) // same volume but counter not running yet Volume = count * 0.5 // convert counts to milliliters Interrupts() //Enables interrupts on the Arduino MlCounter = EEPROM.get(0) // read out the counter from EEPROMĪttachInterrupt(digitalPinToInterrupt(intrPin), Flow, RISING) //Configures interrupt 0 (pin 2 on the Arduino Uno) to run the function "Flow" I never really learned coding from scratch, so please don't be too hard on me, but here's my code: // A7 TDS And since the variable I'm trying to save is an unsigned long, I need four bytes. When I only use EEPROM.read and EEPROM.write, I don't get these error messages but I can only read and write one byte. 'class EEPROMClass' has no member named 'commit'ĬhatGPT says this is because the EEPROM.h library was changed recently and all these functions have been removed with version 2.0.0, but I can't find any information about this and the official documentation still has these functions, so I'm thinking ChatGPT may have just made that up. 'class EEPROMClass' has no member named 'put' 'class EEPROMClass' has no member named 'get' However, with my current sketch I get these error messages: 'class EEPROMClass' has no member named 'begin' I want the counter to be preserved even when power is lost, so it needs to be saved to EEPROM. The one thing I just cannot get to work is counting the total volume of water, so I know when to change my filters. I started out on a Wemos D1 mini because that was all I had, but then transferred it to an Arduino nano clone (LGT8F328p) because I needed more analog inputs and don't need WiFi capability. I've managed to build a device that can show me both of these things, using different sensors and a small OLED display. Also, the degree of desalination fluctuates during use so I would like to see that too (measured in TDS). I want to know exactly how much volume I'm dispensing so I can fill my kettle perfectly every time. I have a reverse osmosis system that can give me filtered and desalinated water through a little tap.
