  • Inductive Sensing Design Challenge: USB Microphone based on the LDC1000 Inductance to Digital Converter (week 8 & 9)

    I am still working on this project, but again it has been very difficult to find the time to finish things up. It has been a very hectic period at work and I've also just signed a contract for a new job next year. I've also had a ton of practical problems…

  • Inductive Sensing Design Challenge: USB Microphone based on the LDC1000 Inductance to Digital Converter (week 6 & 7)

    The past weeks I've been quite busy, so I do not have alot of updates so far. Therefore I decided to make a combined blog for weeks 6 and 7 as I did for weeks 2 and 3. Thoughts on the frequency counter in the LDC1000 I had another look at the resolution…

  • Inductive Sensing Design Challenge: USB Microphone based on the LDC1000 Inductance to Digital Converter (week 5)

    This week I focused mostly on the software for the LDC1000EVM. There are many questions on the ask TI forum about the protocol which is used on the LDC1000EVM, but there is no real single answer. What is known is that the LDC1000EVM uses a USB CDC (Communcication…

  • Inductive Sensing Design Challenge: USB Microphone based on the LDC1000 Inductance to Digital Converter (week 4)

    I can't believe it's already week 4 of the challenge, but here we are. Michael Kellett 's comments on my last blog post prompted me to do some calculations on the dimensions of my initial design. As such I have put off Matlab and actually 3D printing…

  • Inductive Sensing Design Challenge: USB Microphone based on the LDC1000 Inductance to Digital Converter (week 2 & 3)

    Hello again. This is the second part of my blog on the design of a USB microphone based on the LDC1000. I decided to make a single blog for weeks 2 and 3 since I haven't been able to spend a lot of time on the project these past weeks. Being sick didn…

  • Inductive Sensing Design Challenge: USB Microphone based on the LDC1000 Inductance to Digital Converter (week 1)

    Hi everyone, my name is Sammy Peiren. This is the first blog post for my entry in the inductive sensing design challenge. The basic idea is to build a USB microphone based on the inductance to digital principle. Since the LDC1000 provides a digital output…
