The document provides instructions for extending a UDP server to handle additional commands for reading the state of GPIO pins connected to LEDs on a board. The UDP server extension should accept "read gpio<PORT> <PIN>" commands to check the status of LEDs connected to pins 13, 12, 14, and 15, and reply with the pin and state like "GPIOD.15=1". The ncat utility can be used as a UDP client to send commands to control the LEDs or get their status by communicating with ports 5678 and 1234 of the UDP server, respectively.Networking essentials lect3

The document provides an agenda and overview of key topics related to networking essentials including the network layer, IPv4 and IPv6 packets and addresses, and network address translation (NAT). Specifically, it discusses network layer characteristics such as addressing, encapsulation, routing and de-encapsulation. It also examines IPv4 packet headers, fragmentation, and maximum transmission units. IPv6 is introduced as improving on IPv4 by providing increased address space and simplified packet handling. Network address translation is defined as a method for mapping an IP address space to overcome IPv4 address depletion.Networking essentials lect1

This document provides an overview of a training on timers and PWM for bare metal embedded systems. The goals are to learn clock control, generate 1Hz signals using delays and timers, and create PWM signals at predefined duty cycles. It explains clock control diagrams and settings, and provides code examples to generate a 1Hz signal using delays, use Timer4 to toggle a pin in an interrupt handler, and set up PWM on Timer4 Channel 3. Finally, it lists an individual task to control 4 LEDs with PWM using different channels and buttons to fade the LEDs in/out.Bare metal training_02_le_ds_and_buttons

This document provides an overview of training materials for an embedded starter kit focused on bare metal programming of LEDs and buttons. The goals are to create firmware to control LEDs and read button presses, learn about the hardware operation of LEDs and buttons, and learn GPIO input/output and interrupt basics. It introduces GPIO configuration as digital I/O with pull-up/down resistors or analog, covers GPIO pin functionality, and discusses using interrupts to address the delay issues of polling button states in a main loop. The practice section has the learner set up a project to control an LED based on a button press via polling initially, then refactors to use interrupts to eliminate delays.Bare metal training_01_hello_world
