how to compile new tasmota firmware by simplest way

[tasmo_compiler]

Sorry, for asking again for using your knowledge how to define the build.
As you did it in the past, can you please give an hint to define the LCD Button
for the I2C OLED Adress I2C: PCF8574A found at 0x3c seperate as the other 6 PCF8574 Ports

here is the Log from last build:

00:00:00.128 I2C: PCF8574 found at 0x22
00:00:00.129 I2C: PCF8574 found at 0x24
00:00:00.141 I2C: PCF8574A found at 0x3c
00:00:00.143 PCF: Total devices 3, PCF8574 output ports 6
00:00:00.172 BRY: Berry initialized, RAM used 3138 bytes
00:00:00.184 Project tasmota - Tasmota Version 15.1.0(TasmoCompiler-esp32generic)-3_3_0(2026-01-11T01:07:55)


Thank You for You Help - i only want to know about the define options in user_config_override.h to get this working in latest release for
self-compiling. This would be interesting to me and the community.

Thank you so much
