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 […]
I’ve been wanting to try project Trellis out for a little while now, I was impressed with the open source toolchain for the ICE40, however the ECP5 has everyones favourite feature (MOAR!) it’s basically bigger and faster – what’s not too love. There is a slight issue with the current state of the toolchain, but […]
As anyone who’s regularly used a Pi in their projects knows, sooner or later either the power gets lost unexpectedly or you manage to lock it up playing fast and loose with low level coding… and you’re likely left with an SD card that’s corrupted. Equally with a finished project you don’t want to ssh […]
For literally years, I’ve wanted to start a project using a 32×32 RGB matrix, however they have been prohibitively expensive for some time. Granted you can still pay a fortune for them but I managed to pick this one up for £18 at Pimoroni, which isn’t cheap but still affordable… I no longer had an […]
I’ve had a Pi4 (4GB) for a few weeks now and overall I have to say I am really quite impressed! and for a curmudgeon like me that’s saying something… (bonus video at the end of the post…!) The first thing to discuss is temperature, while for the first week I was using the Pi […]
A pattern I have found myself using a number of times is a pool array, you can just use an array, and simply scan over it when you need to find an unused item, however that can be a little inefficient, another strategy could be to use a linked link and allocate and free individual […]
Its common with logic circuits to have a number of similar groups of logic elements, for example a counter can be made from a number of master slave flip flops. Rather than recreate this part of the circuit multiple times, create a circuit and assign in input and output pins, these are then used when […]
I’ve implemented two new nodes in cLogicFun, a source label and a destination label. It’s not uncommon to see the same signal introduced at numerous different points in a circuit. This means for common signals that are needed in many places you don’t need to route wires all over the circuit. They have a special […]
For a little while now I’ve been working on cLogicFun, and while its far from perfect and definitely a work in progress you can do quite a bit with it. There are a number of examples provided but first lets take a look at the different “nodes” you can add to your circuit. AND, OR, […]
