Happy to be wrong but I fear you cannot do a hard reset on that series of alpha displays. You need to cycle Vcc.

Ditto. Perhaps you could put a permanent link on the forum home page?

My understanding was the if you are doing High voltage programing then PGM becomes normal io. I also think (and may well be wrong) that the Pickit provides the equivalent of the clock, so xtal or rc...

I just checked and I don't think there is any assembler in the INC file? Did I miss something?

Getting rid of dongles can only make the product, name apparently in doubt, more attractive. I for one detest the little usb port using, useless pieces of pointlessness.

Colin, the demo, I2CPrintHardCommand_SerEx.bas (what a pompous title for simple program) compiles under 3.7.3.9 What version are you using? What error message do you get? Is your main file and the...

FWIW the fuses you posted in post #7 seem to be correct for 2550. Dodgy crystal maybe, write the blink to be sure to be sure.

Of course if you used a PIC device with PPS.

John, one of the most common reasons that a USB device is not recognized is clock. You must be absolutely certain that clock is 48MHz. Create a blinky if you haven't already then post fuse config.

MC have a whole bunch of sample descriptor in the MLA. One great thing about this USB implementation (as opposed to the built-in commands) is that the descriptor format is similar to MC's own, make a...

You really lucked out because I thing 90% of the learning curve for 3d printing is conquering the 2 or 3 CAD packages before you find the right one for you.

I should have said that in this application weight is at a premium.

I already have a LED strip mounted on the gantry so I'm just looking to fill in the shadow under the extruder.

@KenK What range of values of resistor would I need for 4 LEDs?

@Tim You seem to be making great progress, what CAD are you using?

Anyone using Tet should be extremely careful, that stuff is very toxic.

I'd like to have a LED attached to illuminate the nozzle on my 3d printer. To save running additional power cables, the 24v fan on the extruder heatsink is always on while printing. Is it possible?...

I think that only works with ABS.

I'm interested in producing mechanically sound parts, usually in either PETG or ABS. What is the relative strength of "resin" (what sort of resin is it anyway)?

Yes Prusa use quality parts but as I said 750$ for a kit seems like you'd have to use it a LOT. They do sometimes do odd things though, like their modified V6 which seems to be an issue.

Can't find it now but I think my 2 cell unit has 4 wires. Seems like 2 cells ought to have 4 wires. May be wrong though.

PM'ed you (and made space in queue)

Flosi, I don't even know what a cascading style sheet is.

Lester, atleast I have ads on for this site (the only exception to my no ads rule)

How very odd that they (CCS) would waste their ad budget like that.

Hi, I'd like one but I'm in Ireland. I'm happy to pay postage up to say £15, if more let me know. PM me.

Pretty much all Pic devices (last 10 is years) allow an alternate clock which can be set really slow.

In the short term you always have the auto load function.

I no longer use PicKitPlus but when I tried it I used "-w -e -a3.3 -pPIC$target-device$ -f"$hex-filename$" -mpce -d5" (without the overall quotes but with $hex-filename$) for 3.3v

The posted code is subroutine, you cut and paste it into your program.

PPSTool is here devices file is here. It has the option to upload latest files from MC

John's PPS tool does not cover 18F but PPS Tool (on Github and part of GCB) does. FWIW Tim I believe your RA0PPS and RA1PPS values are correct.

@basparky Just as Creality did recently.

In short, yes.

A way to get binary values to display correctly is to avoid going back and editing the page but even better is an attachment.

All that accepted, it's got to beat the shit out of Mplabx.

Personally I use Proteus for debugging algorithms and serial terminal for real hardware.

I really don't think this is the way forward, if you want a debugger, port the existing (but not working) user written debugger to the latest version of Proton. It is called P-IDC.

Good luck with MplabX, the spec and all the features looks great the implementation sucks the big one. Don't even get me started on IPE.

Evan posted earlier that if he'd changed PK2/3 firmware (which he decided not to do) he could have made it even quicker.

Perhaps I misunderstood. You posted that your test worked on the 14K20 but not on the 13K20 and I pointed out that I suspected that as the 14K20 was marginal with 768 RAM, the 13K20 would be even...

@Evan, I was referring to the way that mplabx and ipe change pk2/3 firmware at a whim (I guess there's some rule but I dumped IPE as soon as I could and mplabx sucks so hard it leaves me speechless)...

FWIW I'd agree with your choice although give how MC play fast and loose with that aspect of the PK2/PK3

Can't find a reference but I vaughly remember Les posting that 14K50 was marginal, if so 13k50 even more so (768 vs 512). Only a guess but as they share a DS it's one of the few differences.

It's great to hear PicKitPlus development continues and I would defiantly have got it if I hadn't previously found NSDSP, using LVP this thing is so damn fast, sometimes I do a (redundant) verify...

Yea, it's neat isn't it, the quys who wrote it showed up MicroChip.

Of course if you use the MSSP directly you have many selectable clock sources but I doubt if you can go that slow. Anyway I see your using 22 bit so forget my post.

I seem to remember you could buy 3.3v 16x2 alpha modules.

Edit In fact I have one if you want to borrow till you can source one.

The problem with the backpacks you can buy is that there is so...

The CH340 is found in pretty much anything where the budget is too tight for FTDI. eg Arduino clones

Why not dedicate a PIC device to reading the encoder and sending the result on demand?

As I posted previously, if you use the format



you will need to change the appropriate property in Proteus.

Me too (prepay that is). To repeat myself, I think this is a great step forward for Proton and hopefully for you, Les. Do you have a notional list of libraries?

You need to monitor USB 5v with a GPIO.

In both cases 5v will not be present on USB input. It simplifies things if you power your project from USB.

Another example might be where a battery power key fob used sleep to save power and a irq from a bunch of key depression ioc's

I find that if I post code with binary data and don't subsequently edit it, it displays ok. I'd like to try you code, perhaps you could repost?

@johngb I wish I could unfortunately my brain is far too small, I find even the newer 18F's ie 18F27K42 much to complicated, the ADC alone is enough to cause considerable hair lose.

@kuhrig In my opinion arrays on 16F and to a certain extent all PIC devices are severely complicated by the segmented nature of paged RAM. Personally I would use an intermediary variable, you only...

@mjturner Thanks very much for the excellent code for RC522. I'm trying to port to 18F25K50 and curious why you used the SPI hardware directly and not thro one of the SPI commands ie SHIN/SHOUT?

The only difference between the two versions provided is method of generating I2C either bit bang or MSSP.

@Joe I have similar to your s-l16004.jpg 4 wires, apparently 2 loadcells and different legend on ADC board.

@Joe what colour wires do you have from the load cells and how are they connected?

I wonder if there's anything here will help https://www.theengineeringprojects.com/2018/08/introduction-to-pic16f88.html

Just curious, but why are you persevering with this Pic device? I suppose you could try LVP (assuming you aint messing with RB3 (PGM)

@Maxi - are yu sure about that? its just a breakout board after all?

You do not need code, rx/tx is completely transparent.

For example a wireless GPS. HC-12 to the rx/tx on the gps, another HC-12 to a ttl to USB dongle. Fire up putty on the PC and bob's your uncle.

@David

on the register description for OSCCON, above IRCF0-2 the text R/W-0 means the register is read/write and resets to 0.

According to Les, the trick with binary display in this forum is NOT to edit after adding.

@Giuseppe Thanks for the video link, good info but the voices are so duuullllll. It appears that by luck I have genuine parts.

The thing that throws me about drones is the massive disparity in prices between machines that have (apparently) the same features.

Doesn't that rather imply that it's off by default for 14-bit devices?
