I was thinking late last night and I forgot to mention the LCD backlight control. I know I said the PCF8574 only uses 7 pins, that's not totally true. I forgot to mention PCF8574 P3 is actually the LCD backlight control.. So I stand corrected, the PCF8574 uses all 8 pins to control the LCD. So the s...

Thanks. I've usually used these LCDs in 4-bit mode, with 6 lines (just grounding the R/W, which just means you have to give it enough delay that you know each instruction is finished, since you can't poll it). I have working sample code in different forms at http://wilsonminesco.com/6502primer/LCDc...

Hi Garth.. Thanks for your comments and kind words, Yes they are 5v devices, I think the PCF8574 will even run at 3.3v (I've not tested), but I don't know if that will have any effect on the LCD (I will have to test that). No I don't actually sell the I2C module or LCD, for me here in the UK they ar...

I just wanted to share that I have added a new module for Swordfish so you can now use the cheap LCD displays with the I2C PCF8574 chip boards

Link to the I2C LCD Swordfish page

pickit4device.png I thought this was worth sharing that you can now use the PicKit4 with the Swordfish IDE to now programme microchips using a command line.. As time changes I guess we all have to move with the times, I still have my much loved PicKit2 and PicKit3.. Also Swordfish now supports some...

I have been soldering some fine pitch 0.5 MCU's and 0603 components recently, they have been fun used a lot of desoldering wire on these MCU's...

Sorry for a late reply here..

The picture quality is good, and the soldering joints have turned out perfectly, looks very clean

I also use Acetone to finish off my boards!..

Is this tutorial still valid or has something changed? I must be doing something wrong if it is. Hi Vallance, Has this tutorial was posted by a forum member, and the links/code seem to be missing I would gather this tutorial is no longer valid. Is there something we can help you with specifically? ...

So sorry for the late reply guys :oops: A lot of things going on at the end of this year, which meant not much time to visit the forum. Thank you Garth for your recommendations, I will take that on board if I ever redesign or remake this board, has it happens the board actually turned out fine and w...

I've recently seen a bunch of youtube videos relating to JLCPCB, 10boards for $2, that seems a lot cheaper than iTead PCB, So I thought I would give it a go with my next project. I've placed my first order with them for 50mm X 50mm 10 PCB's which came to about £1.41p here in the UK, wth shipping the...

I think the post got deleted I'm afraid. The "Raptor IDE" I was talking about actually got renamed just before it was release to "Firewing", this can be found at the following link. http://www.firewing.info/ I've done a lot with the Firewing programming language and fully recommend it if you are use...

Hi Joyce, welcome to the forum..

Yes I've seen you have been busy, looks like Retroball is doing very well, I'm sure ill be backing it but waiting too see what funds I have over next few weeks :) I really like that you've designed it around the arduino and pic. There seems to be a lot of discrete components there - are they mainly ...

As we all love anything electronic and to do with gaming here I thought I would share this! :) I was a Kickstarter backer to this project back in Feb 2017, and I have just received my kits (July). The Makerbuino is based on the GAMEbuino except that it's a kit that you build yourself which includes ...

If this is a genuine post then isn't it just down to the compiler optimisation levels?.
