We have a bit more than the usual curated content this week.
This week sponsor, Intergalaktik, is giving away an advanced FPGA board!
I’m talking about the versatile ULX3S 85F. One of you, subscriber of our newsletter, will win this board in 1 week!
Happy reading and good luck!
Thank you to Alfonso Luna for the header’s picture.
Impressive implementation of the USB protocol (host and device sides) with PIO of the Raspberry Pi Pico. The video demo is great as well. Three Pi Pico chained via USB!
