Built and ready to experiment with firmware - need to make a display driver possibly with hardware scrolling, possibly with DMA, disabling both the backlight and the display itself in power-saving mode, fonts, then decisions on layout.... then keyboard and bouncin.... then the actual brains of the calculator:)

A lot of fun. BUT! The ground has thawed to the depth of a shovel, you have to dig and plant and dig again. I am extremely inactive in the spring in terms of hobbies:)

Когда хочется портировать старые игры, но нет ни сил, ни времени: запускаем отсекатель лучей на RISC-V RV32I

Всех, кто работает с софт-ядрами, наверное, можно разделить на две категории: первые хотят запустить на своем ядре Linux, вторые — DOOM. Я отношусь ко второй: идея запустить DOOM на ядре YRV, что я синтезирую на отладках, любезно предоставленных FPGA-Systems.ru , преследует меня постоянно и не дает спать. Как запустить DOOM с ходу, непонятно, ведь у меня все-таки некоммерческий микроконтроллер. Поэтому начну с подготовительного упражнения, чтобы понять, что возможно реализовать на аппаратной части. Когда мы говорим про DOOM, то вспоминаем другие игры любимой компании id Software — Wolfenstein 3D, Catacomb 3D и Hovertank 3D. В них все начинается с алгоритма отсечения лучей (raycasting), с которым и будем поработать. С raycasting можно получить и doom-образный геймплей, надо лишь улучшить разрешение и текстуры.

A new RISC-V SBC.

Here is the desktop set up on the Mango Pi Pro #RISCV #SBC. As mentioned earlier it is running minimal #LXDE on top of a vanilla install of #Ubuntu server 24.10.

I have peeled back a few things, such as audio since the basic Ubuntu install does not have the stuff to run #HDMI #audio (I could do look into this more but eh). I will do some more tinkering with the ISO from the official Mango Pi website. Lets see how that goes

Currently I am playing around with the Mango Pi Quad (#ARM) and the Mango Pi Pro (#RISCV) and doing a few comparisons.

Both have minimal #LXDE set ups and both have identical 1gig ram modules. On the Quad I am running #Debian 12 and on the Pro I am running #Ubuntu 24.10. So not necessarily and apple to apples compassion. But what I find interesting is that there is only a 13ish percent difference in #RAM use. The Quad after start up hovers around 25.1% ram use while the Pro hovers around 38.9%.

Maybe RISCV will catch up sooner than later with ARM. More random thoughts to come. Both are fun lil #SBC if you can get a hold of them.

Muse Pi Pro is a Raspberry Pi-sized RISC-V PC with M.2 and mPCIe sockets

The Muse Pi Pro is a credit card-sized computer with a RISC-V processor, an AI accelerator, support for up to 16GB of LPDDR5x-2400 RAM, and up to 128GB of eMMC 5.1 onboard storage. But that’s just the tip of the iceberg.

While the little computer is the same size as a Raspberry Pi Model B, it has onboard M.2 and mPCIe sockets that let you add an SSD or cellular modem, as well as MIPI-CSI and […]

i am really excited to be able to teach "digital literacy" inside our program about "future skills" inside @haufegroup

we will build a gemini capsule using pi picos, and iterate incremental until full yunohosting a piece of the fediverse at home. all while touching solarpunk ethics and free software.

RISC-V With Linux 6.15 Adds Support For BFloat16 "BF16" Instructions | @phoronix

https://www.phoronix.com/news/Linux-6.15-RISC-V

All parts of the calculator body are printed from wooden PLA, all boards and blocks are soldered. What remains to be written is the firmware #riscv #ch32v003 including the display drivers (along with software backlight adjustment) and the keyboard driver, based halfway through @RueNahcMohr 's ideas.

Anyway, the fun part begins

I don’t plan on buying more x86 CPUs, but I will if necessary. Hopefully, I can keep using the ones I already have. My goal is for my next daily-driver CPU to be RISC-V. My Ky-X1 is for development; it’s not quite ready to be a daily driver yet, I suppose.
