  • Testing ER-TFTM028-4 Capacitve Touch Display

    Nov 21, 2020 display reverse-engineering

    Good debugging equipment priceless. Being able to gain insight into a system in a quick and clear manner greatly helps identify when issues occur. In first versions I like to add visual feedback for myself. This can be as simple as an RGB LED to detect status or as full featured as a touch screen display. For my senior …

  • Debugging Occasional Incorrect SCD30 Results

    Oct 23, 2020 scd30 saleae

    Currently, I am working with a Sensirion SCD30 CO2 and RH/T Sensor Module for both work and Senior Design. The module includes an IR led detection chamber for measuring CO2 as well as a SHT** relative humidity and temperature sensor for calibration of the CO2. This improves integration and is a pretty good deal if one …

  • KiCad Move Block to Sheet and Retain Annotations

    Oct 20, 2020 KiCad Tips

    The Problem Currently, I am working with one of my senior design capstone team members to develop and create the schematic. To get going faster and be sure to give everyone the opportunity to work on the design, we took alternating turns on design and layout. This created a problem for when we wanted to refactor the …

  • Un-killable microSD Card

    May 27, 2020 FatFs microSD

    In a previous post, I was talking about getting FatFs1 up and running on a custom board. However, I was having issues related to the power supply. My first hint was investigating if there were power fluctuations and if the SD was being provided the proper amount of power through the switch. This was my initial thought …

  • SD Cards and FatFS

    May 26, 2020 FatFs microSD SAML11

    Okay, I am not happy to admit I have spent far too long trying to get a SD card to work on my own PCB and microcontroller. I have always worked with Wiring based libraries in the past. This is essentially the Arduino ecosystem of libraries, so I have never had to dig down into the implementation. If you find yourself …

  • PMSA003I and Embedded Serialization

    May 23, 2020 Ghidra PMSA003I

    The PMSA003 is a small (sub $20) particulate matter sensor. As with most PM sensors, this module uses a fan and a laser to detect the size and counts of particulates in the air. As I am using the I2C version for current project, I needed to write the driver for it. When creating the struct, I realized the sensor's data …

  • Same or Reversed Wiring Harnesses?

    Jan 19, 2020 harnesss JST socket-socket

    There are two common ways to assemble wiring harnesses, of which appear to go by several sets of names. Most notable pairs are: "same" vs "reversed", otherwise known as "socket to socket" vs "socket to socket reversed", as well as, 1:1 vs 1:N styles. Regardless of the naming …

  • Starting the Tuning Fork Gyroscope, Background

    Jan 17, 2020 gryoscope mems piezo tuningfork

    For my sensors class, we have been tasked with designing some form of a sensor from the ground up. My group, consisting of a grad student, a fellow undergrad and myself, chose to implement a gyroscope. Gyroscopes are instruments used for measuring angular rotation. They are commonly packaged with accelerometers and …

  • VirtualBox Graphics Corruption

    Nov 27, 2019 virtualbox

    Today I was setting up a VirtualBox instance to run Linux Mint 19 in a Linux Mint 19 host. After boot, I was greeted with an unreadable graphics issue. Turns out sometimes VirtualBox, when running on Linux based hosts, will exhibit a screen buffer corruption in the guest when first starting. The solution, found on …
