I haven't done any further tests with the UDP controls, but I captured some more traffic in order to try to figure out how is the video transmitted between the quadcopter and the mobile phone. The communication seems to be established through port 8888...
I'm going to create a stand-alone PSoC project to use the PSoC to read SD cards. I'm going to start with the hardware defines for this project (which should leave the Z80 hardware pins unmolested) and just not download code. For the software piece, I...
Hardware testing is complete on all the jump and branch instructions. So that's the first 8 out of 256 instructions tested! The next 24 are loading operands. These should work fine since the jump/branch instructions are also loading operands in order...
When entering a short test sequence on my remote this is what my receiver displays (a dot means an exact repetition of the previous packet):All on: 07 B0 F2 EA 35 90 01 B9 AC F9 .......................... 07 B0 F2 EA 35 90 00 B9 74 E0 .. Color red: 07...
Huaxing Intelligent Control UWBLOC positioning system adopts self-developed wireless pulse ranging technology to achieve precise positioning of exhibition hall personnel and exhibits. The positioning accuracy is better than 30 cm. By setting the base...
The STM32 board was just a hair bigger than the PIC, but the biggest pieces are still the power switch, channel button, & battery. The plan is just to print an L enclosure which scotch tapes around the hot shoe & sticks up. The antenna will...
My friend Dylan Brophy inspired me to investigate the ability to output the cyrillic text using different output devices, supported by Terminal-BASIC. 1. Using symbols others then capital latin in identifiers not possible and unnecessary. 2. USART output....
Initially I thought the data stream from the camera board to the quadcopter controller was PPM. This signal is only active when the app is running and the on-screen controls are brought up. The quadcopter has to be power-cycled in order to be controlled...
Here are some "Quickstart" instructions for the Menu, BASIC, VTL2, and Visual/02 programs in Mike Riley's alternate program ROM. They're not a full manual yet, but will get you started and give you a "taste" of vintage programs and languages. A Quickstart...
Before I start this log on the keyboard I should mention that I'm in the process of putting all of my writings and software on the Video Writer on a small website. The following is an almost direct copy of what will be the article about the keyboard......
How It Works Brief Summary I started with a well-known disassembly of Combat (by Harry Dodgson, later improved by Nick Bensema and Roger Williams). To this, I added a K-nearest neighbor algorithm that uses examples from a training dataset to make a...
In a previous log I said, "I'm not going to overthink this. Random selection from the chess openings is working.". Well I lied. I am going to overthink this. (Well at least think it.) Something I should have done when working on the opening moves was...
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
