Hi.
I have an ESP32 Wroom with MAX6675 Thermocouple.
This is my config:
- platform: max6675
name: "Temperatura Stufa"
cs_pin: GPIO15
update_interval: 10s
spi:
miso_pin: GPIO23
clk_pin: GPIO21
If I leave the CS wire connected in the GPIO15, the sensor always signals 0 degrees.
If I disconnect the CS wire from the ESP32 board, the sensor oscillates between 2, 64 and 66 degrees
What did i do wrong? Thanks
Not sure if it helps, but this guide usually helps me finding suitable pins: https://randomnerdtutorials.com/esp32-pinout-reference-gpios/
I have a thermocouple on an ESP32 working using the following pins and aligned with the VSPI bus:
spi:
clk_pin: GPIO18
miso_pin: GPIO19
sensor:
- platform: max31855
cs_pin: GPIO5
I have tryed, but no results.
