Micropython and C Play Together Better

Python is a versatile, powerful language but sometimes it’s not the best choice, especially if you’re doing work in embedded systems with limited memory. Sometimes you can get away with MicroPython for these cases, but the best language is likely C or assembly. If you’re really stubborn, like [amirgon], and really want C and Python to play well together, you can make use of his new tool which can bring any C library to MicroPython.

As an example of how this tool is used, a “Pure MicroPython” display driver for ILI9341 on the ESP32, which means that everything was implemented in MicroPython. [amirgon] wanted to see how the Python driver would compare to one that’s already been written in C, and use it to showcase MicroPython binding. This tool also automatically converts structs, unions, enums and arrays to Python objects, and provides a means to work with pointers which is something that Python doesn’t handle in the same way that C requires.

[amirgon] hopes that this tool will encourage the adoption of Micropython by removing the obstacle of missing APIs and libraries in MicroPython. Since most libraries for systems like these are written in C, a way to implement them in Python is certainly powerful. We featured one use case for this a while back, but this is a much more generic fix for this coding obstacle.

Crypto exchange Binance prepares to add margin trading ‘soon’

Binance, the world’s most prominent crypto exchange, says it is close to adding a much-anticipated margin trading feature to its service following weeks of speculation. The company tweeted confirmation of the upcoming feature in a screenshot which subtly teases the imminent arrival of margin trading options. Binance CEO Changpeng Zhao (pictured above) first revealed that the feature was headed to Binance during a live stream following a hack earlier this month that saw Binance lose around $40 million in Bitcoin . TechCrunch understands that margin trading has been beta tested among selected users. A Binance representative declined to comment on the specifics, but did confirm that margin trading will be available on Binance.com “soon.” Dark mode or Light mode ? #Binance pic.twitter.com/pGSb1np4yp — Binance (@binance) May 24, 2019   Margin trading, which lets traders use their balance as collateral to super-size their buying power, is seen by many as an important growth...

The hidden cost of food delivery

Noah Lichtenstein Contributor Share on Twitter Noah Lichtenstein is the founder and managing partner of Crossover , a diversified private technology fund backed by institutional investors, technology execs and professional athletes and entertainers. More posts by this contributor What Studying Students Teaches Us About Great Apps I’ll admit it: When it comes to food, I’m lazy. There are dozens of great dining options within a few blocks of my home, yet I still end up ordering food through delivery apps four or five times per week. With the growing coronavirus pandemic closing restaurants and consumers self-isolating, it is likely we will see a spike in food delivery much like the 20% jump China reported during the peak of its crisis. With the food delivery sector rocketing toward a projected $365 billion by the end of the decade, I’m clearly not the only one turning to delivery apps even before the pandemic hit. Thanks to technology (and VC funding) we can get a ri...
