Programming an ATtiny 1614 using UPDI
The ATtiny 1614 is an 8-Bit microcontroller available in a SOIC-16 form factor. It has 13 available GPIO pins (Not
Build a UPDI programmer from a USB to UART adaptor
To build a Unified Program and Debug Interface (UPDI) programmer, I started with a USB-2TTL “USB to TTL Serial Communication
KiCad Traces Net classes
I have done the following work on Net classes in KiCad, which is derived from what I wrote about IPC
UART TX/RX Swapping made simple
When designing boards, one of the things I spend a lot of time checking is if my UART transmit (TX)
Additional Addressing of Nodes
This looks like a way to allow for addressing nodes on a CAN, RS485 or DMX network without needing to use either DIP switches or PCB changes.
Adeept vs Navigation Raspberry Pi Hats
I have an Adeept Robot HAT, but the Blue Robotics BlueOS works natively with the Navigation hat (it’s probably pedantic,
Serial issues with the Arduino Pro Micro
The Arduino Compatible Pro Micro and the Arduino Leonardo both use the ATmega32u4, which has built-in USB communications. While this
How to measure cable loss using an ESR7
To more accurately measure emissions from a DUT (Device Under Test), it is wise to calculate the path loss, or
Programming an Arduino from the command line
As part of my K9 and ROV projects, I am using at least one Arduino to control components such as
Special Symbols used in Engineering Reports
When writing reports and other technical documents, you tend to need to use special symbols. Such as μ when referring
Capacitor value prefixes
Farads (F) is the standard unit of capacitance in the International System of Units (SI). One farad is a massive
