recently i had a bad day,
and play breadboard wiring with INA and ADS
and burned my finger?
assuming some boards/ measuring sensors got damaged.
but with recent discussion about ADC that
* ESP Ain is to avoid
* PICO Ain "hmmm OK"
* Arduino 5V Ain better even only 10bit?
OR use external ADC board
i need to check on the
ADS1115 board again ( or order a new one ),
connect to PICO W first
( it was working using CircuitPython, but with Arduino IDE never try )
PICO W & ADS1115
use it in big project code
breadboard wires
PICO W & ADS1115
-1- what is PICO W?
PICO family
Pinout
-2- what is ADS1115?
* a I2C connected (default 0x48)
* 4 channel ( or 2 differential )
* ADC ?16bit,
* 860 samples/s
*programmable gain aka measuring range: 0.256V, 0.512V, 1.024V, 2.048V (default),
4.096V, 6.144V
* max volt allowed: Vdd +0.3V on Ain (so here 3.6V )
datasheet
there are many different boards , i have
and when i burned my finger from it the chip must have been real hot
so, how to connect and use 2 differential inputs?
and the real hardware ( measuring a battery Voltage on ADS differential input )
and the readings / screenshot
start from using the example code.
lucky it still works fine
use it in big project code
start with making a new TAB
ADS.ino
and copy in the above example code.
and in 'secrets.h'
#define use_ADS1115
also make again that decision NOT report ADS1115 values separately
if you use ADS1115 means you not want use internal ADC,
so just overwrite A0 A1 internal ADC values
and because of increased resolution, i have to pass that somehow,
by defining A0 A1 is now in 3300.000 [mV]
project code name will be:
PICO2_ESP_WIFI_newMQTT_WEBPAGE_INA_ACS_ADS_V270.ino
now also shows more info in web-page
breadboard wires
not want to make a extra BLOG,
but also it not fit in here well..
my breadboards and jumper cables are very old...
contacts might be corroded whats bad when work analog signals
then i buy a set of these (m-m / m-f / f-f wires )
what are good esp for board-sensor connection without breadboard
but the f-male 'plugs' are a little too small for header pins and come 'back' from the black plastic,
when apply the needed force to plug it on a board header pin
there is a 3rd option for breadboard,
ready wires, these i just order.
using these i see some nice looking breadboard projects
