The main processor right now is a Laptop running a packet sequencer I wrote in EXCEL utilizing the built in VBA to send serial data.

Hola Beau Schwabe

If the TS does not opose, could you elaborate on that. I always foun difficulties of different kinds to acchive it. The function serial comm never being available, the most frequent.

A legal version of current Win 10 and 2016 (IIRC) of Excel could make it? I am not scared of VBA.

If deemed convenient I could start a thread. Gracias.

If I know it right, still there are few space craft out there with the 1802.

Yes, they were used for their low power consumption, resistance to cosmic rays etc, and because they are easily reprogrammed remotely - as far as I'm aware a number of deep space probes used them? (the type aliens upgrade and send back, destroying everything in their path - except the Kirk!).
 
We're still servicing our old indicators... Still have a few 1802's knocking about... Its the support chips we cannot get...
 

I'm using Microsoft Excel 2010 along with NetCommW7 .... The old MSComm did not want to play nice. Aside from that, just a few google searches to figure out how to read the CELLS to formulate the Packet and read and write to the serial com .... It works on an indexing approach where a cell is clicked like a button and sends the sequence at a particular index (<-Row) at a certain column location in the row, there is a delay (time before next packet is executed) and in another column the next index to jump to. It's really quite crude, but effective for the intended purpose.
 
I don't think I have any favourite microprocessors, just ones that I'm familiar with, and so those are the ones I use.

I've noticed that no one's mentioned TI's MSP430 series. Anyone use those?
 
The multi-drop serial , I am doing wireless with HC-12. theoretically up to 127 drops 0x80 address is used for ALL, 'Slave' TX delays prevent collisions, slave is configured remotely ..
 
Guys check it out. So tired. I'll write better tomorrow..

LPC-2101 Core

Ok just got some boards in and this was the first one to get soldered up. BTW all my soldering is iron and heat gun. No ovens anymore. It’s a LPC-2101 all broken out with RTC battery. Don&#82…

Ian I'm going to try and setup a little DOS box and get it running. I miss qbasic.. if for at least help me bring back some memory of my past.
 
If you can't find a copy I can send you one..

QBasic - Abandonware DOS

QBasic is an abandoned application , developed by Microsoft and released by Microsoft in 1991. QBasic runs on DOS.
www.abandonwaredos.com

GW basic is also on there...

It's sad we miss these crappy programs... You'll be pulling your hair out very soon...
 
Hah awesome thanks . I'm driving at work right now.. well parked to be exact.. I downloaded it to my phone. Can't wait to play.

Was looking through.. saw the name Borland.. ugh I used to use Borland C++.. memories

Never used C++, but other Borland stuff was great - FAR faster than other compilers.

Quite amusing though that over the years, as processors got faster and faster, the in-built software loop 'Delay' routines started to fail, as the processors got so fast the counters over flowed. Luckily, they released a small program that edited the .EXE and cured the problem - a side effect of this, was that is was absolutely amazing how many commercial products were written used Borland compilers.
 
I first got my feet wet with a PDP11, some bright soul had taken a run of the mill data processing computer and turned it in to a CNC machine controller!
I modified the magnetic core memory teletype loader input for 'Modern' RS232 !
12 bit assembly.
Max.

Sounds good.
Can you tell us what it is and what it does, or is that information commercially confidential?

Can't tell you what it is or does because of NDA but I can show some of the machinery ...

That carriage assembly reminds me of a machine that I worked on a few years ago. But, all of the microprocessors in that project were already embedded in the PLC, and in the motor controller. So, all I got to program were the PLC and the motion control program in the VFD. It was one of the first flux vector motor controllers that could position control a standard 2 HP 3 phase motor as fast and as precisely as a 2 HP servo motor.

My first 'repair' to take the spider out of the 256 byte core matrix..( first electronic cash register a huge great orange beast) may not have been the spider but it worked afterwards.. The next generation had bubble memory. then some nonvolotile Toshiba -13.8 volts to 'write / save' before shut down' unfortunatly was prone to static corruption.. then NVram .. turned out non-NVram then NiCd battery backed CMOS .. Batteries leaked Then i got made redundant !
