Code RebuildI rebuilt the code for a different staing point. Instead of: B(t)=(1-t)^2*B0+2*t*(1-t)*B1+t^2*B2I refacted the equation to: B(t)=(B0-2*B1+B2)*t^2+2*(B1-B0)*t+B0The error squared for each "t" is: e^2=((Bx0-2*Bx1+Bx2)*t^2+2*(Bx1-Bx0)*t+Bx0-Xi)^2 ...
There are several translation routines found during the file sending stuff that translate one character value into another one. Some we understand, like this one:F4DC sub_F4DC: F4DC 84 7F anda #$7F ; reset high bit F4DE 16 tab F4DF 4F clra F4E0...
Revisiting the RAM signature stamping knowing what I know now, I can better see what's going on and record that knowledge. The RAM stamping routine now looks like this:F723 ; stamp 'ram valid signature' on RAM page 0 and 3 F723 stampRAMsignature_F723:...
One last thing that was still missing was the symbol table. Apparently the output of the softmax layer maps directly to the symbol table, and since this output is 128 in length, I was searching for a table of this same length.The prime suspect was of...
1/30/2021 - bringing up boards notes Sch/brd name Wedding 5Using Atmega328PBAAA battery footprint (not AA as mentioned before) still not quite rightProgramming over ISP works, power supply worksProgramming over FTDI/ UART works, I found this to be finicky,...
I did another test with the rev1 prototype, this time only measuring voltage, and bringing it all the way to the maximum voltage of 60V. Again I am doing calibration and comparison to my Fluke 101 Multimeter. This has a problem as the Fluke 101 does...
One thing unresolved bit of the LCD is the R/~W line. I had largely assumed that the display was write only in this product, but I was quite wrong as reading is needed at least to poll the 'busy' bit in the status register. I had found the...
In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...
Yesterday before sleep I replace LD271 IR LED and this morning oficially started data gathering.On the pic you can see my morning glucosis test. Unfortunately the hour is wrong, need to fix it.What I found strange is the variation of measurements in...
The oven gives you a bunch of informative feedback over serial about its current operation. For example, here's the output from a reflow process: Reflow Started Profile Settings (1) PreHt: 100°C, 80s Heat: 180°C, 220s Ref: 240°C, 30s RefKp:...
In this chapter, the fundamental concepts of hexapod robots such as walking gaits, stability, kinematics and dynamics are covered which are essential to obtain a better understanding of the control architecture that is delivered in the next chapter....
