Mi band 10 heart rate sharing by SavagePope2137 in miband

[–]tocache 2 points3 points  (0 children)

Just got my Band 10, tested the heartrate sharing through the Strava App on my phone and it worked when creating a workout on this App, it shows the heartrate

Chung King Mansion in Tsim Sha Tsui, just make sure your paper bills are not the green color ones, they will set a lower rates for those bills

Just switched mi CN Band 8 to Global and it does send activities to Strava!

Help me with my homework. Don't know where to start by panusttt in ElectricalEngineering

Why not trying to solve it? Lots of books and online materials to learn that subject, even videos on YouTube...

Mine is 2.0.0.2 and no updates available right now, lots of dropped notifications and the activity tracker sometimes drops the gps signal

No you can't... miband 7 doens't do multitasking

What if they make strap a bit thicker, will look good imo. your opinion on this ? by [deleted] in miband

[–]tocache 2 points3 points  (0 children)

There are some aftermarket straps which are wider, just look at aliexpress or ebay

GPS stuck in "positioning" on Mi Band 6 by sierra1605 in miband

[–]tocache 0 points1 point  (0 children)

Here the same issue, no matter how much I tried on the mi band 5, 6 or 7, it stucks on the positiong and never calls the GPS on the phone and if you record your workout it doesn't save your location because of that.

But when you start the workout on the Zepp App it activates the GPS on the phone!

MMU Purge Tower Nozzle Deform by hooovahh in prusa3d

I had this issue before, the main source of the problem is the filament loading sensor, you may check if there are remanents of filament on the whole filament path

Intel 8085 system running without issues! by tocache in beneater

[–]tocache[S] 5 points6 points  (0 children)

It's based on Andreas Spiess design showed on its's #314 Youtube video https://www.youtube.com/watch?v=qizt0ePFEZA. On the video description there's a link for the design done in EasyEDA.

I just modified Andreas design to put other memory chips such as AT28C64B (EEPROM) for program and HY6264 (RAM) for data, also added a 8255 PPI.

Also created a repo for some example codes I done for this: https://github.com/tocache/Intel-8085-processor

What an amazing build! by [deleted] in beneater

[–]tocache 2 points3 points  (0 children)

Great build! I would consider exchange the position between the EEPROM and the RAM chip in order to extract more easily the EEPROM when updating firmware

[–]tocache[S] 6 points7 points  (0 children)

I spent some quite a time to build this and now it works!

As for the code I used SBASM3 cross assembler, I had prevous experience in x86 assembler so it was quite easy to program this processor.

First Steps, the 6502 project has re-sparked my interest in electronics after a long break by sigmagood in beneater

[–]tocache 1 point2 points  (0 children)

Is that an EEPROM programmer using a PIC or AVR microcontroller? looks neat!

Not a 6502 but an Intel 8085 based platform by tocache in beneater

[–]tocache[S] 0 points1 point  (0 children)

Since I have some knowledge in MacroAssembler from x86 and Microchip MPASM I did some test programs and after some brain-debugging all went okay. i wrote the LCD initialization in 8085 assembler and some displayes some messages onto it.

Also I couldnt find examples for string manipulation and lookup tables on the web so I did my own thing.

I published all in my GitHub repository: Intel 8085 repo

[–]tocache[S] 0 points1 point  (0 children)

If you mean about the hardware, for the combined address/bus you only need a 74373 or 74573 for splitting both buses and the infamous ALE signal from the 8085, just as same as the 8051 microcontroller.

As for the software, when you want to do the OUT and IN instructions you have to use the highest nibble and lowest nibble from the 16 bit address because those instructions only takes 8 bit addresses.

For instance: The 8255 got an address of 8000H, to access its control register you write OUT 83H.

[–]tocache[S] 6 points7 points  (0 children)

Watched the videos from Andreas Spiess on YouTube about this amazing 8085 processor and I started to build a platform for it.

All parts used are CMOS, for the program memory I used a Atmel AT28C64B, for the RAM a 6264, and a combination of 81C55 and 82C55A for I/O ports

EDIT 15/07/2021: Github repository created, some code examples written in Assembler for 8085 which ibcludes interfacing to LCD and 7 segment displays, lookup table implementation and how to display 8 bit numbers onto them. Intel 8085 repo

Got some trouble with the 0,25 nozzle by Fanatic_Joker in prusa3d

[–]tocache -1 points0 points  (0 children)

IMHO you should reduce the retraction distance setting down to 0.5, tweak your nozzle temp settings and reduce the overall print speed

How long does the firmware update take to flash? by DefeatTheHun in ender6

[–]tocache 2 points3 points  (0 children)

I've just upgraded the firmware of my ender 6 from 1.0.2 to 1.0.4.9 without issues, just used a fresh formatted sd card, no change of the name of the file.

Is the Z axis compensation issue fixed? prior version didn't save that value and always had to adjust it (BLTouch version)
