Hey, great that you are passionate about embedded software! Your current path to learning C and computer architecture is present.
You must have a good understanding of various hardware interfaces like I2C (https://discrete.co.in/blog/i2c-protocol-in-embedded-systems-working-uses), UART, SPI, GPIO, CAN, etc.
From here, focus on mastering embedded C, data structures and RTOS. For the interview, understanding hardware-software interaction, microcontroller basics and debugging is key.
As for development kits, once you are confident with the basic concepts, get a popular one like STM32 or Arduino to start practising. Self-study is possible with dedication and practical projects.
Keep up, ask questions and use online resources. You are on the right track!

To program ATmega64A, ATmega128A, or ATmega2561 using a USB ASP programmer, you need to connect the following ISP pins:
MISO (Master In Slave Out): Pin 2
MOSI (Master Out Slave In): Pin 3
SCK (Serial Clock): Pin 4
RESET: Pin 1 (Connect to programmer’s reset pin for programming)
PEN (Programming Enable) is not necessary for ISP programming. It is mainly used for High-Voltage Programming in some cases.
Ensure proper connections and fuse settings for successful programming.

It looks like your STM32 Nucleo F303RE is stuck in a loop where LD1 (Communication LED) is switching between red and green. This may indicate a problem with the ST-Link connection or a firmware issue. Here’s what to try:
Check ST-Link Drivers: Make sure ST-Link drivers are properly installed and updated.
Reset the board: Try resetting the board using the reset button or disconnecting and reconnecting the power.
Reflash Firmware: Reflash ST-Link firmware using ST-Link Utility.
Debugging Mode: Try using the debugger to find out if your code is causing the problem.
These steps will help stabilize the connection.
