Not all that useful on its own, but it does allow you to push code into RAM and run it. 2025-04-15T16:34:11+02:00 https://nostr.ae/nevent1qqs0mzr57vnv0w2j7w24mmgm0pk78smsqtzj93j95ktvsynpqwq63xgzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snwyksqdm In reply to <a href='/nevent1qqs2yr29vry35mnryqt5nqv7aaz2w9e7us887eylrutag590zrlexrgfukse0'>nevent1q…kse0</a><br/>_________________________<br/><br/>How does the clock switching work?<br/><br/>The CPU has two clock inputs, CLK and FCLK. CLK is intended to be a ~32KHz crystal or oscillator, used for timers and as the very first CPU clock source. FCLK is &#34;fast clock&#34;, and needs to be at least four times faster than CLK. <br/><br/>So, the two oscillators for FCLK are controlled by a GPIO line and an inverter, ensuring that when one oscillator is on, the other is turned off. By default, the GPIO line on the CPU that controls it is an input, not driven, so the pulldown resistor drags the line low, which shuts off the 8MHz oscillator, and feeds the inverter, which sends a high signal to the enable of the ~1.8Mhz oscillator.<br/><br/>Note that you need to select the 32KHz clock as the CPU clock before and during the change from ~1.8MHz to 8MHz to avoid a probable crash or other problems.<br/> <img src="https://studio8502.files.fedi.monster/media_attachments/files/114/342/426/597/068/714/original/4e162907582f68cd.png"> <br/> 2025-04-15T16:25:57+02:00 https://nostr.ae/nevent1qqsrjtf3hl643ckuf0kvtefk7e3f6zcy6n58x0ptpk9ussy3qup224qzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snwh6e4xr In reply to <a href='/nevent1qqsgx40remq9g4zwp3t7fffgr34mxt9xkvh3qkkgc2su5q04ql9vruclw3rff'>nevent1q…3rff</a><br/>_________________________<br/><br/>Not until I get a working prototype of this final design -- I only sell what I know works, unless it&#39;s being sold *as* broken. 2025-04-15T16:22:15+02:00 https://nostr.ae/nevent1qqs2yr29vry35mnryqt5nqv7aaz2w9e7us887eylrutag590zrlexrgzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snwzhwgna In reply to <a href='/nevent1qqsd5p6v0g85qykh97up7nvaddpwawm0c2n7l66rvkfa3wfudqx2y6qwwtjrc'>nevent1q…tjrc</a><br/>_________________________<br/><br/>So, why the ~1.8MHz clock? Well, the ROM monitor has a list of frequencies it is programmed to accept, and that&#39;s one of them. 8MHz, the rated speed of the CPU[1], is not one of these speeds, so I picked one that was close in performance to an 80s micro in case you want to play with 6502 emulation mode.<br/><br/>[1] My testing indicates it can actually handle up to ~14MHz without a problem, and might go as high as 20MHz with the right setup! 2025-04-15T16:21:43+02:00 https://nostr.ae/nevent1qqsd5p6v0g85qykh97up7nvaddpwawm0c2n7l66rvkfa3wfudqx2y6qzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snw2gy99u In reply to <a href='/nevent1qqsqu2nydqllxyvks830r5vqa29a0uzhw4g5usdhzlzwf7d2u54ny6qnmwl9h'>nevent1q…wl9h</a><br/>_________________________<br/><br/>The CPU can manually pull CDONE low if needed; this is to enable software-controlled updates to the FPGA&#39;s ROM via the hardware-accelerated SPI function. It can also control the FPGA&#39;s reset function. 2025-04-15T16:17:15+02:00 https://nostr.ae/nevent1qqsqu2nydqllxyvks830r5vqa29a0uzhw4g5usdhzlzwf7d2u54ny6qzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snwkznjy3 So what happens when you turn on your Sentinel 65X board?<br/><br/>First up, the CPU boots up. This is complex compared to the plain W65C816S, but the short version is that it begins clocked by the 32KHz timer oscillator. It then probes the ROM, looking for the string &#34;WDC&#34; at 0x008000; if it finds it, it jumps to 0x008004 and that lets the ROM take over. Otherwise, it switches to the ~1.8MHz clock, and calls the ROM monitor, which uses the serial port for I/O. <br/><br/>The system ROM is supposed to take over, and instead switch to the 8MHz clock.<br/><br/>Meanwhile, the FPGA loads its bitstream from the serial flash ROM, and becomes the VERA, outputting 640x480 256 colour video. Once that&#39;s done, it pulls the CDONE output high, which goes to some logic that moves the select output from the serial flash ROM to the SD card port, thus enabling hardware-accelerated SPI for SD card access. 2025-04-15T16:15:35+02:00 https://nostr.ae/nevent1qqsvqvz94vs9sgts2emqgmwzu04teq7yp0gasrtmc6cmetcc529pxfszyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snwfgvl3d One of the unused pins on the CPU has a function where it changes state based on a timer underrun. So I have wired that (via a 0Ω resistor/jumper) to the NMI input, thus allowing timer 4 to generate an NMI event under program control, giving programmers yet another option for timing.<br/><br/>The 0Ω resistor is a hedge -- if it turns out not to work for whatever reason, I just mark it &#34;do not populate&#34; and the connection is severed. 2025-04-15T03:03:00+02:00 https://nostr.ae/nevent1qqs8g48tlk69fnefr8uv6kvvkp9ud50f86rtucq7l9sg3zfgreqh9mszyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snw8x79e5 Magic: The Gathering deep cut hot take: &#34;Innistrad&#34; is just &#34;Homelands&#34; with better cards but the exact same setting. 2025-04-15T01:06:18+02:00 https://nostr.ae/nevent1qqsx3v3mn2xc5p8yqryy4tdmzgr2apzx5x64y53hu56vyzshlskejwczyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snw9693v9 In reply to <a href='/nevent1qqsp0t8h3rnd5ctjkma4cm7xj3gnvympg2uhtf09hspevql4csfahtgf8gdd5'>nevent1q…gdd5</a><br/>_________________________<br/><br/>The price per unit will probably be about $125 USD. 2025-04-15T00:55:43+02:00 https://nostr.ae/nevent1qqsp0t8h3rnd5ctjkma4cm7xj3gnvympg2uhtf09hspevql4csfahtgzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snw6ulqpx In reply to <a href='/nevent1qqsf5wqzgxdw72a800clqp6n0j4lamqxx999v9ljsdsm46vqynvw6pc9ykwfm'>nevent1q…kwfm</a><br/>_________________________<br/><br/>I&#39;m working on that, of course. 2025-04-15T00:55:25+02:00 https://nostr.ae/nevent1qqsf5wqzgxdw72a800clqp6n0j4lamqxx999v9ljsdsm46vqynvw6pczyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snwkhqf76 In reply to <a href='/nevent1qqsd22rmplg9letmc0xpf9n0wqpuhqd75sm8tnz4pyc7skyh330q7ngc8qt0w'>nevent1q…qt0w</a><br/>_________________________<br/><br/>First I get hold of a test unit to make sure the design works, and if not, fix whatever is wrong.

I can’t articulate it, but something feels like it’s supposed to be there and isn’t. 2024-08-26T05:57:56+02:00 https://nostr.ae/nevent1qqs9rdj6gtxguskmrtg8egue2hsaszm7ph07ve5fzpsh8z7pkx00r5qzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snwrnfeys In reply to <a href='/nevent1qqsvkfe6l3rykwrey2x8gdqlmwsk6dyx0nsg7hqzm9kvl747yjsm3sq9ygagf'>nevent1q…gagf</a><br/>_________________________<br/><br/>Bye, cuntface. 2024-05-15T02:12:14+02:00 https://nostr.ae/nevent1qqszrn0fctj37952l8kyhzpj0ncldmdhyy8ha9nmcg7ds2y59q5ygcqzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snw9sd7ss I will say it again. The left abandoning the language of morality to the right is *why* we have right-wing religious zealots claiming the moral high ground -- the moralized perspective, even twisted as theirs is, is more attractive to an average human than a logical one, even when the moralized one is demonstrably false, misleading, and dangerous. <br/><br/>We do not support LGTBQA+ rights because it is politically useful, or because it&#39;s fair, or because it&#39;s just. We do it because it is *morally correct* to do so.<br/><br/>We do not support UBI for logical or practical reasons, even though those are essentially correct, we do it because it is *morally correct* for all people to enjoy a dignified minimum standard of living.<br/><br/>It is also useful, if it matters to you, that framing these practical policies in moral terms frees you to paint your opponents as immoral by definition -- and that, too, appeals to the human psyche. 2024-05-15T01:45:12+02:00 https://nostr.ae/nevent1qqs9wvfvq5pt4y683ct8wxx6kpdkqhwhf2qejswwamytmgdzsz9g4pszyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snw5dq806 In reply to <a href='/nevent1qqsvfkm9rpuf08mg79424td79mthyenwk7a9clr83zq6hlxtr00uxjsvghxhc'>nevent1q…hxhc</a><br/>_________________________<br/><br/>Yeah.

Wayland is a fine go-between for the programs and hardware, but I just don&#39;t like combining the window manager with the display server and the hardware all in one, it&#39;s anti-Unix. 2024-05-01T04:02:56+02:00 https://nostr.ae/nevent1qqsfdlzhjsdgkz4cyf0na32tamtq5haca0nprm3k5lm3k2vuqx2kcvgzyqz03y25ynr3xet66m89j3pa9rdaeavry6runt6kpt3c3avjw6snw8re8fw Help me out: Let&#39;s say I wanted to build a desktop that used *only* X11 applications, but still used Wayland to actually talk to the hardware -- a full XWayland setup. I know how to do that, but what I don&#39;t know is which compositor is most suited to that use case -- the XWayland server running in a rootful mode, filling the whole screen, with no other Wayland clients running.<br/><br/>So which compositor fits that model best? 2024-05-01T03:28:31+02:00
