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...
Using a counter for the ISRI received a suggestion to use a counter and trip method for the Interrupt Service Routine (ISR). While is was not keen as the method (Direct Digital Synthesis) is pretty standard and gives the best long term accuracy. But...
TLDR Spoiler Alert! This is a walk through for the Badge Enabled Non Directive Enigma Routine (B.E.N.D.E.R) v2.0. Major storyline and context is left out because it's assumed you have a badge, have given up, and just want to learn WTF was going on (and...
After I convinced myself that the emulator was probably OK, I turned back to the ROM. But after I found yet another ROM image online, and it turned out to be identical to the other three, I have to rule out bad ROM as well. Just as well as I was...
As you can see below, I am breadboarding the new peak detector changes before committing to a new PC board. One of the changes involves using a MAX5387 digital potentiometer to control the square wave amplitude and EC amplifier gain. The...
As for the equation that will be used to determine whether a neurotransmitter triggers one of the intervals in a neuron, it will be as follows:where the numerator represents the sum of the specific neurotransmitter (t) from the neurons that are active...
We have just published a tutorial on how to properly setup and calibrate your Incremental Quadrature Encoders with SOLO to control the Torque, Speed and Position of your BLDC, PMSM or Coreless Brushless EC Motors. https://www.solomotorcontrollers.com/how-to-connect-quadrature-incremental-encoder-to-solo/...
The rebalance is still progressing. It's particularly slower because I also changed the failure domain on my cephfs EC pool from OSD to HOST which increased the number of PGs that needed to be remapped. Aside from that, the rate of progression...
Add with Carry To date I have used plain and simple ADD with my DIY CPUs. ADC (i.e. add with carry) is useful for multi byte (nibble) addition as the carry is automatic. The downside is that the humble counter does not work, it skips 0. This can be fixed...
So when I type in commands into my remote for ESP32 the motor controller spits back hex data. It easier on the eyes in decimal so here a little to look atKeep alive command19 38 20 0 44 213 0 82 0 0 80 0 0 7 0 0 255 1 153 186 0 158 0 0 0 0 0 0 32 0 2...
I guessed that the phone app opened some sort of socket communication channel with the "aircraft-ctl" program running on the camera board. I figured the thing to do was to try to capture the packet stream between the camera and app and then find out...
I have connected the opt8241 sensor over I2C. I have disabled sensor clock by setting MCLCK to 0. Power consumption of adapter board is ~1.8 mA. Then I have sent the i2c commands. Command output : # i2cdetect 2 WARNING! This program can confuse your...
They say that a picture is worth a thousand words, so: As you can see, THE NEW PEAK DETECT CIRCUIT WORKS! It's always nice to see something work in real life versus simulation. It's kind of hard to see exactly how close the peak detect output...
