From version 1.2 any publication will includes all U2F firmware files for 40 & 80 Columns.

A thirds number in publication (eg: 1.1.1, 1.1.x) refers to an intermediate development version until it is finally published as a major version (say 1.2).

Version 1.6.0.32 - (ongoing)

New GPIO attribution for expansion connector for applying to "Pico Vga Terminal" and "RP2040 VGA Terminal".

Features

  • Documentation review (see GPIO usage on expansion connector).
  • add picoterm_harddef.h to store hardware definition
    • SD Card initial support with pio_fatfs (version of FatFS over PIO SPI). Using GPIO 26,27,28,5. Voir main.c, spi_sd_init() et spi_sd_init().
    • I2C bus moved to GPIO 18 & 19
    • PoorMan Debugger moved to GPIO 22 @ 115200 bds
  • initial support of fatfs over PIO SPI.
    Read more about this from pio_fatfs/readme.txt file and pure SPI pico_fatfs_test repository.
  • initial support of CLI: Command Line Interpreter activated with SHIFT+CTRL+C with several commands.
    The CLI is used to test SDCard interaction and future configurable features.
    The CLI is extended via the cli/user_funcs.c file.
    • sd_info
    • dir
    • type
    • send_file
  • Adding keyboard hotkey (1.6.0.31)

Fix & Improvement

  • Sending escape sequences for keyboard strokes: SCANCODE_CURSOR_LEFT, SCANCODE_CURSOR_RIGHT, SCANCODE_CURSOR_UP, SCANCODE_CURSOR_DOWN, SCANCODE_PAGE_DOWN, SCANCODE_PAGE_UP, SCANCODE_HOME, SCANCODE_END, SCANCODE_DEL, SCANCODE_INS (see pmhid.h)
  • keydb should pump message only for keyboard (not the mouse). See Issue #43 (Thanks Abaffa for suggestion)

  • Use CMAKE_CURRENT_SOURCE_DIR ro generate pio header file (see CMakeList.txt, Thanks Juzzas, >1.6.0.31)
  • set_env.sh to quicly setup the environment. Call it with source set_env.sh .
  • rename conio slip_character() to put_char() - more conform with putc()
  • set PICO_XOSC_STARTUP_DELAY_MULTIPLIER=64 when compiling as suggested by Spencer Owner.
    On some boards/samples, the xosc can take longer to stabilize than is usual (see this adafruit_itsybitsy_rp2040.h)

Version 1.4.1 - Dec 2 2022 - NupetScii fix for CP/M

In version 1.4, the NupetScii font does displays strange behavior on CP/M WordStar (& Turbo Pascal) because the 8th bit is used for reverse video display.

This V1.4.1, allow to switch between VT100 ASCII (8th bit for reverse, default) and NuPetScii making it a breeze to work with CP/M.

Tested with WordStar and works as espected.

Features

  • VT100 ASCII is the default Font used (7bits+8th bit for reverse)
  • Being able to switch between NuPetSCII 8 bits vs VT100 mode (7 bits, 8th bit for reverse).
  • Store the NuPetAscii vs VT100 option in Flash
  • Keyboard SHIFT+CTRL+L quick shortcut to switch between Nupetscii and VT100 on the fly.

Version 1.4 - Nov 27 2022

This realease now support extended characters set (> 127). The extra charset is based on NuPET ASCII (NuPetSCII for short) from Tom Wilson.
Big thanks to Tom Wilson and its Character-Editor for autorising the NuPET ASCII charset inclusion.

Remarks: NupetScii ruine the WordStar display under CP/M. This version is replaced with 1.4.1

Features

  • Adding support for NuPetSCII charset (for char >127).
  • CTRM+SHIFT+H : display Help screen
  • CTRL+SHIFT+N : display the Charset on screen.
  • Revamp CONFIGURATION menu with NupetScii

Fix & Improvement

  • rename display_menu() in display_config()
  • Can change screen color without limits! Thanks to Spock64 for fixing issue #14 :-).
  • Using picoterm_config_t typedef definition & extern declaration to fix compilation issue. Awesome contribution of Spock64 (Issue #13).

Version 1.3 - Nov 12 2022

Features

  • Adding Purple color to 80 cols
  • Many improvement in configuration screen for both 40 & 80 columns version
  • Can be modified on the fly without saving (press ESC).
  • Saved to Flash by pressing S (Uppercase "S") --> will Reboot.
  • Change of Baudrate (115200, 57600, 19200, 9600, 4800, 2400, 1200, 300)
  • Change of data bits (7 or 8)
  • Change of Stop bits (1 or 2)
  • Change of parity ( None, Even, Odd )

Fix & Improvement

  • rename "80Column Mono" -> "80col-mono" (removing space & camel-case)
    Remove older compilation files: Renaming the project folder will requires you to drop the existing compilation files (if any previous compilation task did occured in "80Column Mono" folder). Drop the folder Build/CMakeFiles/ and files in Build/ .
  • rename "40Column Colour" -> "40col-coulour"
  • Moving USB keyboard code to common/keybd.c (as dquadros does for RPITerm).
  • Single tusb_config.h definition: move tusb_config.h to /common (make tusb_config.h symbolic link from /40col and /80col to ../common/tusb_config.h)
  • Remove _TUSB_CONFIG_H_ definition from main.h (they are not compliled, tusb_config.h takes priority).

Version 1.2 - Oct 24 2022

Features

  • Debug uart on GP28 (see debug.md for details).
  • Display/Hide menu with CTRL+SHIFT+M (ESC will also quit).
  • Adding color selection in Menu (80 cols only)
  • Additionnal Keyboard Layouts
  • Added layout for keyboard FR & keyboard BE. Now supporting UK, US, DE, FR, BE.

  • Welcome screen shows:
  • the tinyUSB version (pico SDK usually use an older version)
  • the Keyboard layout used and its revision number

Fix & Improvement

  • Using GP28 as rx uart @ 115200 for debug_print(). See common/picoterm_debug.h. A global debug_msg buffer is available for sprintf() operation before debug_print() calls.
  • Using struct PicotermConfig to hold software configuration parameter. Using load_config & save_config to load/save from flash. See common/picoterm_config.h
  • Fix AltGR support for all keyboards (including BE & FR)
  • pmhid.h : KEYMAP FR Rev 2 (fix issue on AltGR + 5).
