First try on custom component

ESPHome
1

I’m trying step by step to implement a fram memory module to esphome.

to do so, i’m trying to setup a custom component, to start with, no fany stuff, just setup and loop.

one thing i don’t understand, why is the log output from the setup not visible in esphome.
The log output from the loop is visible.

is it becaus the chip isn’t ready for displaying anything, how can i manage to display these kind off stuf.
Later on in the setup the fram chip is setuped, so i wan’t to display a message that a memory module is found and is ready for use.

This is what i have so far, not much but try to understand why things are going as they go.

If you are accessing the logs using wireless, then the setup message was likely logged well before the wireless connection was established. Try using serial connection to usb to view the logs then reset the module. Should see the complete startup that way with all the setup() info logged.

found out somthing to print out information.
one can use void dump_config() and printout information.
