Version 0.15

This version requires you to update rp6502.py. This is a good time to refresh all the .vscode and tools files from the template.

Only the US and US-INTL keyboards are fully working. Please submit pull requests for new and updated layouts. Read the contributing comments here to get started.

Added support for 2 and 3 stroke dead key sequences.
Added keyboard localization. See HELP SET KB
Added codes to the terminal for enabling and disabling the cursor.
Fixed affine sprites sometimes showing a garbage line
All ARM assembly code ported to C.
littlefs updated to v2.11.2
tinyusb updated to 0.20.0

v0.14

3964cc0

Version 0.14

Changes

The documentation and help has been refreshed for this release. Most of it was originally written by the guy who coded it the day before at a time when all the nouns hadn't been nailed down. It should be easier to understand now.
The RP6502-OS errno system has been completely overhauled to work natively with your compiler's errno.h. There is no longer an oserror and the translation with mappederrno is no more.
17 directory and file management calls added to RP6502-OS.
RP6502-OS call codepage() changed to code_page().
Fix NTP always refreshing after WiFi connects. NTP will now only attempt after the first WiFi connect event and every 24 hours after that.

Beware

cc65 PR pending - Use fork until it's merged.

v0.13

Version 0.13

Changes

Add USB support for gamepads.
Add Bluetooth LE support for keyboards, joysticks, and gamepads.
Remove CAPS and RESB settings.
PHI2 defaults to 8000 (instead of 4000).
Mouse speed was adjusted to work better at 125Hz.

Be aware

Bluetooth BR/EDR is not supported.

TinyUSB host mode is still unstable after all these years. XInput driver is disabled because of TinyUSB instability.

All HID drivers had to be reworked for BLE support. If you have a keyboard or mouse that worked in 0.12 and no longer works, submit an issue with your HID report descriptor.

Adding support for all the weird gamepads folks will inevitably try is more than I'm willing to take on. I'll keep a watch for core things that will help with compatibility but specific gamepad issues will need to be fixed by the community. I left breadcrumbs in pad.c.

Non-W RIA builds will no longer be released. As with third-party boards, you can build it yourself. I will accept pull requests for third-party boards.

Version 0.12

████▓▒░ It's BBS Time! ░▒▓████

🎉 New firmware drop for the RP6502 — and it's dialing straight into the past!

🖥️ System Requirements

RP6502 VGA now requires a Raspberry Pi Pico 2
RP6502 RIA works with Pico 2 or Pico 2 W
- Got a W? Good news: it connects to your WiFi and sets the real-time clock.
- Even better: it emulates a Hayes-style modem so you can call BBSs over the internet! 🤘

📟 Terminal Mode: `term.rp6502`

Say hello to a true CP437 ANSI terminal — no compromises.
Optimized for IBM-style ANSI/ASCII art, it uses the updated RP6502 VGA terminal with:

⚡ Smooth ANSI rendering
🎨 Perfect glyph compatibility
🧑‍🎤 Retro vibes at maximum

The BBS experience is phenomenal.

🔗 Get started with this list of active boards:

➡️ Synchronet BBS List

🛠️ Commands to Know

Set your time zone: help set tz
Set up WiFi: help set, help set ssid, etc.
Need more? Full modem docs and terminal codes:
📖 https://picocomputer.github.io/

⚠️ Known Issues

The modem currently supports raw TCP only
- A full Telnet layer is still in the works

Grab your Picocomputer, fire up the firmware, and log on like it’s 1993!

v0.11

98dc0fe

Version 0.11

This firmware is for the Pico 2. Upgrade your Picos. No other hardware changes are needed.

There are no new features in this release, but all the technical debt has been paid off. The bulk of the debt was in how the USB and VGA libraries were integrated. Since this affects many other systems, and the Pico 2 transition is recent, I wanted to release without new features to make it easier to bisect if there's a regression.

The USB system has been greatly enhanced. You can now plug hubs into hubs, so keyboards with hubs will work. Currently, up to 16 devices are supported and up to 8 file systems can be mounted.

The VGA system has new internals. The scanvideo library was absorbed and modified for our unique needs. This gave a 10% boost in fill rate. The vsync period has also been increased with less jitter.

Most things have been moved to optimization O3. A few places needed exceptions, which has me wondering if I should change the whole project to O1. I feel like some of the advanced optimizations don't account for volatiles and calls to assembly. I think what we have now should be stable, or fixable, and any decision to move to O1 should be deferred until we see what the next GCC looks like.
