- Chris just got back from Teardown 2019. Shows next week will be with guests that he interviewed during the conference, while Dave is away.
- While there, Chris did two workshops, both with FPGAs and the open toolchains.
- The first was a workshop with our sometimes co-host Piotr Esden-Tempski. The workshop involved the 1bitsquared iCEBreaker.
- This used the Yosys toolchain by past guest Clifford Wolf (holy moly that interview was two and a half hours!)
- It also uses NextPNR, which was discussed by Piotr, Clifford and Dave at Chaos Communication Camp
- Altera is now Intel FPGA, if you didn’t remember.
- Git paper
- VHDL vs Verilog
- “Cross platform code” works between two separate chipsets meant for USB C
- USB C PD
- Dave was actually discussing cross VENDOR code, because of the standard register format between the chips.
- Chris also took a workshop with Sean “Xobs” Cross that involved 3 levels:
- Micropython
- C written for a RISC V processor (soft IP core)
- Writing hard logic for the FPGA
- Xobs is co-creator of the Novena laptop and the creator of the Fomu project.
- The Fomu was inspired by the Tomu, a project of past guest Tim Ansell
- Raspberry Pi 4 announced with new specs. Dave not impressed.
- The new Sparkfun Artemis Module puts TensorFlow lite onto a Cortex M4 processor with Bluetooth.
- This is similar to the Audeme project (in a much smaller form factor) by Gerald and Bertrand.
- Dave has made a video about how voice recognition was done in the 80s.
- Udemy is moving to a model where creators must be exclusive. The video is by past guest of the show Robert Ferenec.
- Chris is looking at buying a simple VNA.
- The “Buy/Sell section” of the EEVblog forum links to auctions. Dave recommends finding labs that are shutting down.
- Past guest Derek Kozel suggested to look at the HP 8753, based on this wonderful reference site.
- Beware the phrase “Pulled from (a) working environment”
- One last thing from Teardown, Kate Tempkin did an amazing talk about USB analyzers and software around decoding USB traffic.
- Building a STM32 open source multimeter.
- Simone Giertz (yep, also a past guest!) built a “Truckla” and showed how she did it!
