So far, the communication was the hardest part of every project I was part of. I already did a tool to ease debugging and creating an aplication layer, but still, the hard part was to correctly receive all bytes and in case of error, recover or retry. I tried a lot of things, but none […]
Here at Damogran Labs we do complicated things step by step, like this: Step one. Buy an STM development board. Step two. Write the simplest possible program that makes an LED blink. Final step. Connect the most sophisticated Bluetooth Low Energy module and study 3000 pages of documentation to compile the most complicated software that
This is an outdated post. For the lates windows release and source code, please visit Serial Tool on GitHub. While developing embeded electronic devices, I always have problems with the same thing: how to establish a communication and send/receive some data with a custom predefined protocol. I use UART in almost all my projects, but
Speaking of involute gears and metric screws, this is another little project that celebrates engineering knowledge. While laying sick in bed I decided to make a 3d model of a drill bit. So I took the largest and the most complicated one from our workshop and modelled it in FreeCAD. One of the purposes of
TriPO vs. CycleOps testing After gruelling months of designing and manufacturing the right shaped sensors, we finally came a couple of steps closer to our first proper prototype of our power meter. For all those newcomers to our site: we are producing a power meter that will be placed under your cycling shoe (in a sandwich
At last, the power is in our hands. We have a working TriPO prototype. The graph below shows force, torque and power measured (computed) from the data for one revolution. Starting at bottom dead position, the greatest force is around 130 N, torque 22 Nm, and average power for the whole revolution 22 W. This might
Update (Feb 2018): As this post seems to be quite popular, I decided to write a new post for STM32 USB beginners with example code/project where we port CubeMX generated USB HID mouse to USB HID keyboard. Update 2 (Feb 2018): Here is another post about making STM32 USB CDC device. I (Domen) finaly managed
We updated our Cene the CNC Guide with discoveries we made during our prototyping work. Among them are some that we think may spare you a few hours. Hardware and software setup, cutting parameters, … There is just too much stuff to write all here. You should download the whole package below – it includes:
