seewaw not find it on default address..

[yo2ldk]

looking further, I find that my ESP32 board (M5Stack Atom Lite), using YOUR example - encoder_basic- , not find your I2C - Adafruit I2C Quad Rotary Encoder

"rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 188777542, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0030,len:1184 load:0x40078000,len:13260 load:0x40080400,len:3028 entry 0x400805e4 Looking for seesaw! Couldn't find seesaw on default address"

even if I declare it

include "Adafruit_seesaw.h"

include

define SS_SWITCH 12

define SS_NEOPIX 6

define SEESAW_ADDR 0x49

where is declared PIN A and PIN B in ALL your examples ?? once again,on ALL your example, I find just for switch,neopix led,and all possible, EXCEPT a good example for ENCODER, because i buy it just for that: to use it as I2C ENCODER !! as is name you give it..

What happens if you run the example from the guide? https://learn.adafruit.com/adafruit-i2c-quad-rotary-encoder-breakout/arduino

Thank you for fast reply, this is problem, except red LED from power, nothing happens, on C pin, I put SCL, on D, SDA and declared as: #define SEESAW_ADDR 0x49, on serial have follow message:

"configsip: 188777542, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0030,len:1184 load:0x40078000,len:13260 load:0x40080400,len:3028 entry 0x400805e4 Looking for seesaw! Couldn't find seesaw on default address "

Does the address show up in an I2C scan? https://learn.adafruit.com/scanning-i2c-addresses/arduino

[yo2ldk]

it is present at 0x49, with the same ESP32 board

[caternuson]

Weird. It's showing up in the I2C scan as expected. So unclear why the example code is not working.

Is the M5Stack Atom Lite your only Arduino board?

[yo2ldk]

no, I have also others boards, I will try when I have time but, I need for Atom Lite because not have enough IO ports, more exactly is Atom lite HDMI display, and all his ports is for that driver and, Thank's for your time, help and patience !

[yo2ldk]

ok, this issue will be closed, I found the problem If your I2C encoders boards is not recognised on I2C, just add on void setup the line "Wire.begin(25, 21);" where 25,21 is YOUR xx, xx arduino board SDA, SCL pinout numbers.
