Replacing the ATMEGA328P−MUATMEGA328P-MU (U1) with an ATmega8 involves ensuring that the pins and functionality you need match with the new microcontroller. The ATmega8 is part of the same AVR family and generally has similar pin configurations, but there are notable differences. Here's a general guide on what to change:
  1. Pin Configuration:
    • Ensure that the pinout matches your current connections. While many pins may be similar, verify that critical pins (such as power, ground, clock, reset, etc.) are correctly connected.
  2. Power and Clock:
    • Connect the power (VCC) and ground (GND) pins as previously configured.
    • If using a crystal oscillator like X1X1, confirm that the crystal pins (XTAL1 and XTAL2) match the ATmega8's corresponding pins.
  3. I/O and Peripherals:
    • Check that the I/O pins used in your project match with the ATmega8's I/O configuration. You may need to map them according to the ATmega8 pinout.
    • Verify that peripherals such as SPI, UART, and ADC are supported and correctly connected. Adjust any connections if necessary.
  4. Software:
    • If you're using Arduino, ensure that the software is compatible with the ATmega8 or make required changes to the microcontroller settings in the development environment.
Would you like any help updating the connections or checking specific pin configs?

All GPIOs are wired to the Net Portals. But the names/designators of these Portals are empty so you can fill them in as you prefer. You probably will don't need them all, so you can delete unused ones or leave them blank.
