PICO2-XL and PICO2-XXL OSHW boards are now available for ordering the shipments start January 17th
PICO2-XXL exposes all 48 GPIOs of RP2350. The initial blog for PICO2-XXL development is here. PICO2-XXL is with 16MB external QSPI Flash, 8MB PSRAM and micro SD-card mounte on bottom side of the PCB PICO2-XL is with only 2MB of external QSPI Flash so almost flat on bottom side: The boards produced are testing now, […]

Пишем приложение для SIM-карты
Приветствую всех!
Думаю, многим из вас доводилось слышать такое утверждение, что SIM-карта — по сути полноценный специализированный компьютер. А раз симка — это компьютер, то, очевидно, должен быть и софт для него. Как насчёт попробовать что-нибудь написать и заставить это работать прямо на карте? Давайте разбираться.
Итак, в сегодняшней статье поговорим про эту довольно редко упоминающуюся сторону сотовой связи. Узнаем, как писать приложения, чтобы они запускались на всех телефонах, от Nokia 3310 до последних айфонов. Попутно выясним, как загружать их в SIM-карты и насколько сложно это сделать, и, конечно же, напишем наш первый апплет. Традиционно будет много интересного.

Intel released the powerful Pentium processor in 1993, establishing a long-running brand of high-performance processors.1 The Pentium includes a floating-point unit that can rapidly compute functions such as sines, cosines, logarithms, and exponentials. But how does the Pentium compute these functions? Earlier Intel chips used binary algorithms called CORDIC, but the Pentium switched to polynomials to approximate these transcendental functions much faster. The polynomials have carefully-optimized coefficients that are stored in a special ROM inside the chip's floating-point unit. Even though the Pentium is a complex chip with 3.1 million transistors, it is possible to see these transistors under a microscope and read out these constants. The...

До недавнего времени разрабатывать IoT приложения на C# можно было только для компьютеров построенных на архитектуре ARM или x86. Поддержка RISC-V процессоров для платформы .NET уже давно в стадии разработки. В начале этого года был представлен не официальный .NET 8.0 SDK, который уже сейчас вы сможете запустить на RISC-V процессоре под ОС Debian/Ubuntu. В качестве платформы запуска возьмем одноплатный компьютер Sipeed Lichee RV на RISC-V процессоре Allwinner D1 (ядро Alibaba/T-Head Xuantie C906 RISC-V). В первой части поста рассмотрим установку .NET 8.0 SDK на Sipeed Lichee RV. Во второй, запустим приложение для работы с контактами GPIO и датчиком BME280 для замера...
Name that Ware, December 2024
The ware for December 2024 is shown below.
This one should be a cakewalk, and I’m mostly sharing it because I had trouble searching for a recent example at an image quality sufficient to make out most of the part numbers. Maybe this can help someone else in a similar fix!
Warm wishes for a safe and happy new year to all!
Winner, Name that Ware, November 2024
The Ware for November 2024 is the NLP-16A by cherry-takuan. It’s a bespoke 16-bit CPU made entirely from 74HC00 NAND gates.
Even the D-flip flops are made from NAND gates:
Lots and lots of NAND gates…
I got to meet the maker, who goes by Cherry Takuan, at the Chiba Institute of Technology‘s 75th annual student festival. The NLP-16A was on display in a corner of the Denken electronics club (there’s also a rival club at the event, CITera). I was a little in disbelief at first, but after a bit of hemming and hawing I convinced myself this was in fact...
