[Request][Logic Gate] Binary To BCD Converter
DanHCraft opened this issue · 4 comments
Description
It should convert a 27-bit-number into an 8-digit-BCD-number.
A boundled cable has all 16 colored channels in it with that you can provide an 16-bit binary number.
Also you can provide 4 BCD-digits with one bundled cable, because one BCD-digit has 4 bits.
My idea is that you have two inputs and two outputs each of it with boundled cables.
It is also the perfect complement to the 7-sigment-display.
I/O Sides:
- Input One: Bit 1-16
- Input Two: Bit 17-27
- Output One: BCD-digits 1-4
- Output Two: BCD-digits 5-8
Channel Table
| Color from the channel of the boundled cable | INPUT 1 | INPUT 2 | OUTPUT 1 | OUTPUT 2 |
|---|---|---|---|---|
| white | Bit 1 | Bit 17 | BCD 1 Bit 1 | BCD 5 Bit 1 |
| orange | Bit 2 | Bit 18 | BCD 1 Bit 2 | BCD 5 Bit 2 |
| magenta | Bit 3 | Bit 19 | BCD 1 Bit 3 | BCD 5 Bit 3 |
| light blue | Bit 4 | Bit 20 | BCD 1 Bit 4 | BCD 5 Bit 4 |
| yellow | Bit 5 | Bit 21 | BCD 2 Bit 1 | BCD 6 Bit 1 |
| lime green | Bit 6 | Bit 22 | BCD 2 Bit 2 | BCD 6 Bit 2 |
| pink | Bit 7 | Bit 23 | BCD 2 Bit 3 | BCD 6 Bit 3 |
| gray | Bit 8 | Bit 24 | BCD 2 Bit 4 | BCD 6 Bit 4 |
| light gray | Bit 9 | Bit 25 | BCD 3 Bit 1 | BCD 7 Bit 1 |
| cyan | Bit 10 | Bit 26 | BCD 3 Bit 2 | BCD 7 Bit 2 |
| purple | Bit 11 | Bit 27 | BCD 3 Bit 3 | BCD 7 Bit 3 |
| blue | Bit 12 | Bit Free | BCD 3 Bit 4 | BCD 7 Bit 4 |
| brown | Bit 13 | Bit Free | BCD 4 Bit 1 | BCD 8 Bit 1 |
| green | Bit 14 | Bit Free | BCD 4 Bit 2 | BCD 8 Bit 2 |
| red | Bit 15 | Bit Free | BCD 4 Bit 3 | BCD 8 Bit 3 |
| black | Bit 16 | Bit Free | BCD 4 Bit 4 | BCD 8 Bit 4 |
Largest Number that can displayed with that converter is 99.999.999 .
This feels like a very specific function. I think that somthing like an EEPROM or RAM (#1486) that can map any input to any output would be more useful because it could be used for a lot of different things, including this (but it would require two gates instead of one).
Once I made a binary to BCD converter module with project red fabrication. I made it so you can chain them together kinda infinitely and with that you can have as many bits and digits as you want. It might be slower and harder to setup but in the end it is more flexible. I could send you a schematic of my design if you want.

I apologize for the late answer.
Of cause I would like to have a schematic of your circuit implementaion of the bin2bcd converter.
I thank you very much

Wow I didnt think you whould answer after such a long time (I almost forgot that I posted something)!
It uses Double dabble algorithm: https://en.wikipedia.org/wiki/Double_dabble. I have attached some screenshots from the IC workbench. At the top of the schematic there is BCD output. At the bottom there is clock input. Left side is clocked output to next module. Right side is clocked input from previous module. There is currently no way of reseting the circuitry (setting to zero) other than clocking the clock input few times very fast (should be easy to fix).
I have also included screenshots of my setup. The IC gate "16bit sreg pr" is shift register with paralel input from the bus input panel and serial input from the unconected side. The side connected to BINtoBCD unit is serial output. The side of the shift register connected to bundled cable is clock input [white] and input select [orange] (orange off means shifting in from serial input and shifting out from serial output on negative clock edge. When orange is on it latches input from paralel input on negative clock edge)
There is schematic of my shift register with paralel input:
And also the level.dat file from my save folder-you can use something like NBTExplorer to look directly at my player inventory data (the only item in my inventory is schematic of my BIN2BCD module) and even transfer the data to some other world/inventory.
If you have any problems tell me. Btw I am still playing on MC version 1.7.10. I hope you (or anybody else) finds this usefull.
