Having found the send speed setting, I got a bit interested in the file sending process itself. Tracing back a reference to "Sending....Press any key to stop. " text, I find sub_F013:F013 ; XXX prepare to send (flags and prompt) F013 sub_F013:...
sub_F374 has caught my interest because it seems to be painting the LCD with the currently selected file's contents according to several state variables that I have not fully reverse-engineered.The routine begins like this:F374 sub_F374: F374 BD F6 18...
So since the Teensy++ 2.0 bootloader is not available and I'm not feeling comfortable to learn all the bells and whistles of USB communications I was looking for other options. Googling "at90usb1287 arduino" I found this https://github.com/mattairtech/ArduinoCore-avr...
For those wondering how we assembled the boards, we compiled a video of all the different steps. We started off with prototype machinery (Mechatronika M10 and Mechatronika MX70), manual solder paste dispensing using a eC-Stencil-Mate and reflowing...
Dyson V6 Setup and Running System Dyson handheld vacuum cleaners utilize high RPM brushless DC motors. Specifications indicate that some models can reach as high as 125000 RPM. I’ve disassembled DC56(V2), V6, and V10 models. Each has a brushless single-phase...
Here is the plan. I plan to turn this into this And here is the design block diagram. There will be 3 sensor node and a nutrient control system. All of them is developed with ESP8266 board (either WeMos D1 mini or NodeMCU). I plan to use Blynk IoT...
Today I successfully tested assembled 4-bit ALU (previous revision of NEDONAND-4 board with four NEDONAND-1 connected). In order to do this I slightly modified the board to connect nedoCPU-16 with it: Then I wrote a simple program in PIC assembler that...
1. Toolchain not found After stepping away few days far from my PC for family reason, I resumed my activities on the Tsykuyomi project.So I started by reading the https://github.com/WHhkwong/SIPI_Bear_playback code and looking for a SNC7001A Toolchain/SDK...
For quite some time I have been thinking about the possibility to using a laptop to run all the heavy OpenPlotter and OpenCPN stuff instead of using a Raspberry Pi. The performance of the RPi is... well it's usable but it's not a pleasant user experience....
Temperature is important in soilless cultivation. Articles agree on an ideal growing temperature between 18°C and 26°C. A too cold temperature will slow down growth but increase the dissolved oxygen in the water. While too hot temperature will...
