YvanToday I successfully got <a href="https://toot.ale.gd/tags/Rust" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Rust</a> code working for a <a href="https://toot.ale.gd/tags/RaspberryPi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RaspberryPi</a> <a href="https://toot.ale.gd/tags/PicoW" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PicoW</a> board! Not bad. All credit goes to the toolchains and projects... my efforts here are purely exploratory / discovery. My current status is I got some Pico / Pico W sample code working and then merged some samples together to form a foundation I'll build more code on top of. The merged code achieves:<ol><li>DHCP to local network</li><li>Listen and respond to TCP</li><li>Poke a GPIO (blink)</li><li>Logging to USB-TTY</li></ol>The real TL;DR is: The <code>embassy</code> project seems to be the best starting point for Rust on a Pico W. (Not a Pico 2, this is an older RP2040 board.)The long version is: <a href="https://yvan.seth.id.au/rusty-pico-w.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://yvan.seth.id.au/rusty-pico-w.html</a><a href="https://toot.ale.gd/tags/microcontrollers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#microcontrollers</a> <a href="https://toot.ale.gd/tags/pico" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pico</a>

Bread80Time to try some ROM emulation. The first step is to sniff the ROM enable/disable states and the currently selected upper ROM.The code for this is, again, simple. It tests the I/O address for the ROM select IO port, and also the gate array IO port. If it's the gate array it tests the register select bits of the data and extracts the two ROM disable bits.<a href="https://mstdn.social/tags/FireStarter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FireStarter</a> <a href="https://mstdn.social/tags/AmstradCPC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AmstradCPC</a> <a href="https://mstdn.social/tags/Pico" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pico</a> <a href="https://mstdn.social/tags/RP2350" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RP2350</a>

Dr Footleg (he/him)Question for microcontroller C++ nerds.

And it really was easy!1. Solder legs to the <a href="https://mastodon.ie/tags/Pico" class="mention hashtag" rel="tag">#Pico</a> and put it in a mini breakout board. 2. Connect a micro SD card module and a KY-004 reset switch, to the Pico, with Dupont M-F cables. 3. Copy the repo A: drive files to a micro SD card, and in an H/0 folder copy the Zork interpretator and DAT file. 4. Copy the repo UF2 file to the Pico and insert the micro SD card. 5. Connect to the Pico via USB with <a href="https://mastodon.ie/tags/PuTTY" class="mention hashtag" rel="tag">#PuTTY</a>. 6.

Bread80Todays <a href="https://mstdn.social/tags/RP2350B" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RP2350B</a> school of hard knocks learning experience:The RP2350B has 48 GPIOs but a PIO can only address a contiguous block of 32 GPIOs. You can set the base pin on the PIO to either pin 0 (default) or pin 16.With pin 16 as base GPIO numbers are relative to the base ... unless they aren't. So the call to pio_gpio_init uses global numbering whilst the calls to sm_config use the based numbering.<a href="https://mstdn.social/tags/Pico" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pico</a>

Bread80Boy the <a href="https://mstdn.social/tags/Pico" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pico</a> Gods are shinning on me today. The two PIOs I wrote yesterday are working flawlessly and talking to each other like a charm.

Bread80A weird syntax quirk on PIOs on the RP2350. An IRQ number can be absolute, relative to the current SM number on the same PIO, or an absolute value on the previous or next PIO (ie. relative to the PIO number).The SM relative indicator has to go after the IRQ number, the PIO relative indicator has to go before the IRQ number.REL dates from RP2040, PREV and NEXT are new on the RP2350.<a href="https://mstdn.social/tags/Pico" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pico</a> <a href="https://mstdn.social/tags/RP2350" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RP2350</a>

Bread80That looks like a good start to the weekend.On another project using an RP2350B I couldn't get the USB terminal to connect. I've no idea if it was the hardware or a config issue.
