Can you upload your ESP32 code please (remove all username and passwords surely!)..another question , why am always receiving this warning "Acid priming failed"
Thank you so much . Your answer is quit enough regarding acid priming , i will increase the volume to 1ml,Can you upload your ESP32 code please (remove all username and passwords surely!)..
I prime acid line a bit - as a precaution. It's done by adding 0.5ml of acid to the reaction chamber (before the test) - and checking if PH dropped by a certain amount of PH points (and if not - you may have ran out of reagent OR you have other problems, such as your reaction chamber is empty or your acid line tubing has a leak and it's not full). If you are using acid that is more dilutated, you should prime the acid line with a bit more acid (1ml?) or test for a lower PH drop (0.05PH?)?
This is not a strictly speaking a neceassary step and priming can be left out...
There is also a separate menu item called "Prime" - this is used in sutiations where you disconnected the acid container (say for refilling) and want to re-fill the acid tubing.. I normally do it in a few goes, i.e. select that menu a couple of times to achieve the result..
This looks like a Dev board - same as I use.. Let me look into your issue a bit more carefully..@Borat i have bought a brand new ESP the same model i had before just to test why serial communication not working when settings the UART as follows and still not working .. am wondering do you use the same ESP model if yes have you modified the
Configuration.h file
RX0 , TX0 are occupied by Programming port in ESP32 so how did you managed to use them
so this line never work with me and works with you
Serial.begin(115200);
// Serial2.begin(9600, SERIAL_8N1, 16, 17);
Serial2.begin(9600, SERIAL_8N1, 3, 1);
Thank you so much . This issue is driving me crazy, and am not comfortable pending new board pins to use TX2, RX2 pinsThis looks like a Dev board - same as I use.. Let me look into your issue a bit more carefully..
One favour plz from anyone here whom successfully completed this amazing project. I need a video from the reaction chamber that shows the cortex when stirrer starts.
Also need the exact size of the Stir magnet bar .
Mine is 1CM and not making vortex effect at all but it spins normally with good speed i think
