    Print layout (Slave) til Display OLED modul (16x2)

    You could use a DS1307 clock chip’s RAM as an I2C handoff. That way it could be made to work with most flavors of Picaxes & would be way faster than serial. Would need a “Busy” line from OLED/LCD driver & a “Data Available” line from the Sender. The 1Hz output from the DS1307 is also useful...

    Are Rev-Ed & Picaxe missing out??

    hi manuka. The reference to “AX8052F100 data radio” was just to show an example of a modern 8052-based uProc as a possible host for a modernized 8052-BASIC. The “data radio” portion of the chip might not necessarily be used. A “data radio” could be used to send encrypted wireless data...

    Are Rev-Ed & Picaxe missing out??

    hi Flenser, I have a lot of 8052-BASIC boards left over from projects we did in the 90s, so I haven’t had to buy any in decades. We used them because it was the quickest way to do small add-on projects (barcode gens, joystick controllers for old CNC machines, etc.). It was much faster & easier...

    Are Rev-Ed & Picaxe missing out??

    hi erco, The thing that can be confusing when going from Picaxe to “C-like” languages is the concept of local variables. Unlike Picaxe where variables exist inside/outsite of procedures (aka subroutines in Picaxe), in “C-like” languages, a procedure (subroutine) is like a closed box: i.e. you...

    Are Rev-Ed & Picaxe missing out??

    For-What-it’s Worth Dept.: I am an old retired guy who worked with technology all of my life. Now, I have used C, C++, Java(yuk), etc. and it’s all good (at least sometimes). However… for most of my boating & home projects: The best solution is usually the simplest solution (hello Picaxe)...

    Pulsin and servopos in a loop? I'm getting severe servo jitter.

    hi erco, no experiments needed (note all this stuff is done in “Picaxe Kayak Control” app as well as PCA9685 control (very similar)) (used Picaxe pwmout to set update freq, pwmduty to set pulse width) (note: on my servo I used 0.8ms…2.2mS, depends on servo travel allowed) For a standard servo...

    Saving data into 08M2 internal memory

    The link Phil gave to Dataq is spot on. I used Dataq for years in a heavy industrial environment & it can be used to record & measure just about anything (albeit we used the high-end Dataq stuff). The advantage to their Windaq software is that you can record at very high speeds on multiple...

    Pulsin and servopos in a loop? I'm getting severe servo jitter.

    For-what-it’s-worth dept.: My very first Picaxe project (Kayak Control System) was the hardest one I’ve done to date. My buddy (Lewis) wanted to use a Picaxe-20M2 because it had 4 PWM outputs & he said the circuit-boards would be easier to lay out. Having never used a Picaxe before, I was...

    Utilities for mobile homes, boats etc.

    hi cpedw, Nice project! Good to see other projects related to boating (there's a small subset of Picaxe users on this site who are into that stuff). Could use a similar setup to cool solar panels & repurpose the heat. There's a lot of energy on the water to play with (wind, solar, temperature...

    Simple program for OLED Module 16x2

    look in Picaxe app KYK_MSI1 Software for Picaxe.bas procs (aka subroutines) that begin with "OLED." talk to OLED display (e.g. OLED.position_Set OLED.byte_Show etc.) https://picaxeforum.co.uk/threads/chamberlain-motion-receivers-cwa2000-to-picaxe-via-kyk_msi1-rev-a.32439/ about anything you’d...

    Picaxe Kayak Control Project

    Well… it’s been said that all fishermen are liars. All seriousness aside (I don’t do serious), I think they are just “prone to exaggerate”. However, if you’ve ever hauled up a big catfish & tried to remove a stuck hook, the fish may start a sequence of load belching & it does sound like he’s...

    Help with Servos

    hi Frank91608, The I2C PCA9685 boards as sold by Adafruit may be used to control up to 16 lights and servos in any combination for running programmed sequences. I use one of them for running lighting effects on my yak. Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685...

    Picaxe Kayak Control Project

    hi Ibenson, newplumber, & the rest Y’all be sure & post your projects (I’m always looking for new ideas). Ideally, an electric boat would have a connector that allows quick battery attachment to your home backup power system (if you trailer your boat or live near the water). I use my kayak...

    Picaxe Kayak Control Project

    papaof2 presented some very useful info. Battery research is on fire now, if solid-state pans out, the slate is cleaned (go Toyota). Here's a ready-to-go LiFePO4 system (UPS, solar charging, inverter, etc.) that I found interesting. BLUETTI EP500 5120wh LiFePO4 UPS BACKUP Off Grid Solar...

    Picaxe Kayak Control Project

    hi newplumber, That boat should be perfect for an electrical conversion. Looks like you like to have fun with your projects (me too). The little drives I use might not be big enough for your boat, but the interface could be used with bigger drives by using an adapter cable. I wonder if...
