Hackaday Podcast 221: The Future Of The Raspberry Pi, Sniffing A Toothbrush, Your Tactical Tool Threshold 1 Comment There are technologies such as “via in pad” or “via in pad plated over” = vippo but those come at extra manufacturing costs. Putting via’s in the pads is another sort of nightmare, because solder will wick into the holes and can starve the pad of enough solder for a reliable connection. If you put GND on the outer layer, you also need many more vias, which is also PCB real estate not available for the GND plane. The goal is to reduce loop inductance, which means having a direct return path in the GND plane for each of the (digital) signals.Īnd it’s also not just the pads. The possible extra shielding is offset by the many holes for all the pads. Having GND on the outer layers is also horrible for fault finding and repair.

For even more on the subject, you may like our STM32 Bootcamp series on bare-metal STM32 programming. While initially more time consuming, working close to the metal provides a good deal of additional insight into, and control over, hardware operations. We move on to increasingly advanced topics like timers, interrupts, UART output, debuggers, and even configuring an embedded web server to expose a complete device dashboard. The demonstration continues with setup and use of necessary tools such as the compiler, linker, and flasher.

The guide walks us through writing up a minimal firmware program from boot vector to blinking an LED connected to an I/O pin. aptly defines this as programming the microcontroller “using just a compiler and a datasheet, nothing else.” His guide starts at the very foundation by examining the processor’s memory map and registers including locations for memory mapped I/O pins and other peripherals. When we forego these abstractions and program directly on the microprocessor or microcontroller, we’re working on the bare metal. For example, we often start projects already standing on the shoulders of various libraries, boot loaders, and integrated development tools. Even in the world of embedded programming, were things are generally quite low-level (close to the metal), we’ve grown accustomed to a good amount of hardware abstraction. This generally applies to programming BIOS, hardware drivers, communication drivers, elements of the operating system, and so forth. In the realm of computer systems, bare-metal programming most often refers to programming the processor without an intervening operating system. While the general concepts should be applicable to most any microcontroller, s examples specifically relate to the Nucleo-F429ZI development board featuring the ARM-based STM32F429 microcontroller. Put together this epic guide for bare-metal microcontroller programming.
