This document discusses how to write embedded C code from scratch without using an IDE. It explains that you need a cross toolchain, Makefile, linker script, startup assembly code, and C code files. It then discusses the requirements for C startup, including initializing the stack, global variables (.data, .bss, .rodata sections), and jumping to the main function. It emphasizes that the linker script is important for section placement in memory. Finally, it outlines the key parts of the startup code: exception vectors, copying .data to RAM, zeroing .bss, setting up the stack pointer, and branching to main.Microcontroller part 1

Here are the steps to determine the status of the C, H, and Z flags after adding 0x38 and 0x2F:
1. 0x38 + 0x2F = 0x67
2. The addition does not generate a carry, so the C flag remains unset.
3. The addition results in a half carry, so the H flag is set.
4. The result 0x67 is non-zero, so the Z flag is unset.
Therefore, after adding 0x38 and 0x2F, the status flags would be:
C flag = 0
H flag = 1
Z flag = 0Fpga & VHDL

This document discusses adopting an ASIC verification approach for FPGA verification. While ASIC verification principles like functional coverage, self-checking testbenches, and random stimulus generation should be used, FPGA verification has some differences. Interfaces may use FPGA hardware instead of VIPs and lab testing can run in parallel. CPU and memory controllers can use simpler VIPs and lab software instead of exhaustive verification. Error injection is also important for FPGA verification. Case studies show this approach found critical bugs and improved time to market over lab debugging.Sech1920 1200112979886874-3

For any number of circumstances, obsolescence risk is ever present in the electronics industry. This is especially true for human-to-machine interface hardware, such as keypads, touchscreens, front panels, bezels, etc. This industry is known for its high mix and low-volume builds, critical design requirements, and high costs to requalify hardware. Because of these reasons, many programs will face end-of-life challenges both at the component level as well as at the supplier level.
Redesigns and qualifications can take months or even years, so proactively managing this risk is the best way to deter this. If an LED is obsolete or a switch vendor has gone out of business, there are options to proceed.
In this webinar, we cover options to redesign and reverse engineer legacy keypad and touchscreen designs.

17th International Conference on Wireless & Mobile Networks (WiMoNe 2025) will provide
an excellent international forum for sharing knowledge and results in theory, methodology and
applications of Wireless & Mobile computing Environment. Current information age is witnessing
a dramatic use of digital and electronic devices in the workplace and beyond. Wireless, Mobile
Networks & its applications had received a significant and sustained research interest in terms of
designing and deploying large scale and high performance computational applications in real life.
The aim of the conference is to provide a platform to the researchers and practitioners from both
academia as well as industry to meet and share cutting-edge development in the field.Rapid Prototyping for XR: Lecture 4 - High Level Prototyping.
