[READING A/D VALUES TO A SPREADSHEET Project 70]
Jason sent us this example for a data logger --> to Excell with ESP32forth.
First off, I needed to grab ADC values, and as is customary for me, I like to average them out a little. After some tinkering, I settled on this bit of code:
: DECADC 10 0 DO 34 adc LOOP 9 0 DO + LOOP 10 / . ;
The LDR is connected to pin 34, thus, "34 adc" to read the analog value from pin 34.
Then I cooked up a delay loop:
: delay 0 DO LOOP ;
Finally, I stuck it together in a little loop that allows me to write out values so I can import it as CSV into Excel, which helps me model the data and figure out what I want to do with it:
: SLOADC CR 0 DO DECADC CR 250000 delay LOOP ;
which I can then run thus: 100 SLOADC
which in turn gives me the data in the images you see.
[M5-STACK RUNS ESP32FORTH 71]
Jason sent us this example how ESP32forth runs on his M5stack.
The M5Stack platform would make a perfect portable, self-powered ESP32forth platform. However, to make use of all its features, ESP32forth needs some customisation.
When used with the M5Stack Faces QWERTY keyboard combination, it promises the possibility of true mobility with ESP32forth.
