#34552 Partial working code still under construction... Microchip pic collects data and sends over serial port to ESP

#34583 Additional info:

serial input of [c26.1/1660/43677/71/10]
will change Temp to 26.1c and the degrees F will update along with temperature affected values
1660 update ppm
43677 updates ppm counter the pic uses the ppm counter referenced to a table to generate ppm
71 is the ph -- need add divide/10 to code
10 will be the probe constant , will support 0-255 = 0 to 25.5 , but really just want 1,10

The D,I,W,V send querries to pic which will respond , usually using data window

Current setup:

pic--- > Bluetooth Serial >>>>38400<<<< Bluetooth Serial >>>com14-38400<<< computer |liberty basic bridge software |usb com2 >>>>9600<<<<ESP

#36693
serial
(1.43 KiB) Downloaded 444 times
main file
(11.62 KiB) Downloaded 374 times

The working version attached ...
load both .txt as .lua files and compile then dofile(do140-13wa.lc)
must use external serial in to change the data ...
The pic program that supplies the info I still be worked on.....

#38138 I'm in process of porting this to a sketch, It's been a good teaching/learning tool..

I only have the serial input left to port, and an having issues with that..

The Arduino IDE was not to hard to begin using Ver 1.6.5. I have a lot to learn yet..
I'm just using USBRxTx and ESP and Arduino IDE , I'm not using any Arduino Boards,,,
