TFTP is a very simple UDP file transfer protocol that can be implemented with very little effort and footprint. For this reason, TFTP servers are very crucial for embedded developers even if they are used only for the purpose of firmware upgrades. This article is more of a note-to-self so...

For those of you who haven’t heard about GNU Screen, it is a window manager that multiplexes a physical terminal between several processes, typically interactive shells. It allows you to start, retain, attach and detach to a session across different connections. In lay man’s terms, it’s a life saver when...

At some point in time we all have had to develop some sort of UI for our embedded devices. The thing about UI design is, it can take one hell of a time before we can get it right (and it’s a thankless job! I have my reasons). I for...

Timers are one of the mostly used modules in microcontroller. Almost every system that has to reliably produce time interval or delays will have to use timers modules. The PIC timer calculator is a cool tool that will make life much simpler. If you haven’t worked with timers, I suggest...

Migrating to HI-TECH C compiler for PIC MCU is not really a hard task. The developers have taken much care in keeping it that way. In addition to the existing features of the C18 compiler, there are a lot of other added features in the HI-TECH C compiler. This post...

The MPLAB X is an IDE for developed by Microchip Inc. for their PIC microcontrollers. It has a lot of added features when compared to the older MPLAB IDE v8.xx. TheA MPLAB X is not a new version of the current MPLAB IDE v8. Instead it is a brand new...
