I’m going to show a very simple plug-in, it will show the years, months and days since a given day, to ensure it has a reasonably unique name (which is important) I’ve called it sincer. Sincer will use wordpress short codes to insert the date interval into any post, so first it’s worth looking at […]

Pointers can be a confusing topic for the new C programmer, often explanations get bogged down in too much technical detail, or are just too simplistic. I’m going to attempt to show in both a simple and comprehensive manner just what pointers are and how to use them. First let’s consider the design of a […]

I bought a couple of 68008 CPU’s years ago always meaning to make something, as the 68000 series has a great instruction set and is fun to code on! First job was just to verify that I hadn’t been sent a counterfeit or DOA part… sadly something that is always a possibility theses days. As […]

Its fairly common to see libraries that are written in C++ but only offer a C API (some also offer C & C++ API’s). As someone who much prefers to code in C, I’ve sometimes needed to link my C application with a library that’s written in C++ (for example ODE). My initial solution was […]

For the purposes of this post, a very simple scenario is going to be considered. Given a Model structure that holds a pointer to a Mesh structure, the issue to be addressed is to whether or not there are references to a particular Mesh. Once all Models that reference a Mesh have been freed we […]

While this product is intended to be used with a Raspberry Pi, I bought it specifically to use with my FPGA board, having a HDMI (DVI) port on such a tiny board, just inspires a mobile build! While there is a PI type connector on the board, you can simply use the LCD as a […]

While originally waiting for my board to arrive I found and got a Z80 soft core working (in simulation) I was a little disappointed that tri-state logic seems to cause issues with yosys (I think that might be what was causing the logic “loops” later down the toolchain anyhow). Having recently gotten around to soldering […]

Well, you could knock me down with a feather, if you thought remote programming was blisteringly fast….. File name Time 1 Time 2 Time 3 Time 4 Time 5 Ave Time (ms) /blink.bit 518 518 548 521 522 525 /blink.bit.gz 1140 1140 1142 1141 1141 1141 /blinkc.bit 86 84 87 83 86 85 /blinkc.bit.gz 189 […]

It was pointed out to me that ecppack has a compress option and it has quite the impact on programming speeds, so I thought I’d do a simple test and try a few different compression combinations and see what impact they have (you never quite know with these things till you try) File name Size […]
