@jakobsen_jan Have you tried using my project and running `i2cdetect` command?

[Jan Marjanovič @janmarjanovic]

Please welcome a new addition to my collection of cheap #FPGA boards from eBay. This one is a PCIe variant of Pikes Peak accelerator from Microsoft. (1/8)

Nuclear spins of Yb-171 exploited to manipulate qubits before they are read out - potentially leading to efficient error-correction schemes for trapped-atom computing platforms.

1,180 qubits and counting!

Today, we became the first company developing universal, gate-based #quantum computers to exceed the 1,000-qubit threshold.  Learn more about this accomplishment and our quest to build a fault-tolerant #quantumcomputer.

@RuurdKeizer Yup, the USB chip that implements JTAG needs to be initialized: https://t.co/TmlHV76mEC

Close your eyes, take a deep breath and think about all the packages on can install with Expanded Security Maintenance for Applications. #Ubuntu

We love how creative our employees are and when they find inspiration in their work. Antonia Jones, one of our firmware engineers, recently designed and built her first mechanical keyboard with Atom Computing in mind.

Happy #NationalPeriodicTable Day! Here at Atom, we are partial to alkaline earth metals (group two on the periodic table). Learn why we use atoms from alkaline earth metals as qubits in our atomic array #quantumcomputing hardware technology. #quantum

[DESY (English) @desynews]

Electronic noise is a big problem in micro electronics. A DESY team now managed to measure so-called phase noise with 500 times greater precision than has been possible before. This could significantly improve how electronic components are tested: https://t.co/tqREDlG5wo

[Jan Marjanovič @janmarjanovic]

@vsidou There is a workaround needed to unlock the second PCIe core, otherwise it works fine with a normal Quartus.

[Jan Marjanovič @janmarjanovic]

@vsidou Somehow yes. I have managed to get all the parts running (PCIe, DDR3, QSFP, …) - see my blog series for details, but recently got distracted from my hobby FPGA projects by my new job.

[Jan Marjanovič @janmarjanovic]

With the power of the IPMI (and @picmg_org extensions) and with the ymodem in u-boot, I have managed to bootstrap myself into a Zynq board more than 8000 km away.

@whitequark A good excuse to buy some measurement equipment: https://t.co/gyq1pBZWN8

[Jan Marjanovič @janmarjanovic]

I imagine that it might be a useful feature in some cases, but sending 4 broadcast packets every 15 seconds sounds quite excessive. Anyway, developing the UDP/IPv4 core in the FPGA became much pleasant when I shut down the TCF agent.

[chibby0ne.eth @[email protected] @aguti12]

@azonenberg TCF framework. Used for connecting debug and run control remote targets. It broadcasts to all interfaces on that particular port by default. Check it out https://t.co/ULHV08fJTB

[Jan Marjanovič @janmarjanovic]

@hansfbaier Gennum GN4124 is another device with similar functionality, I have seen it used quite often in some older electronics for particle accelerators.

[Jan Marjanovič @janmarjanovic]

@wing_chester @dsp8bit Yes, it requires the Standard Edition, Stratix V is not supported in the Lite Edition.
