USB libraries, new architecture. Permits composite USB devices (possibilities: HID, CDC and MSD). -- for P18's or P24's with USB --
Version 1.1: Modified so that (changes to) values in "UsbProjectItems" like PID and VID are actually visible in the executable.

Library Blog

Important remarks:

CDC devices:

  • - You need the UsbSer.sys driver (to be present in C:\Windows\System32\drivers) and the UsbSer.inf (to be present in C:\Windows\inf) file. Both can be found here in case they are missing.
  • - Do not forget to add (if not already there) the VID and the PID of your device to the usbser.inf file (C:\Windows\inf).
    The entry in the usbser.inf file in the Windows directory has to look like:
    %DESCRIPTION%=DriverInstall, USB\VID_1234&PID_2000&MI_00
    where "xx" in "&MI_xx" is the number of the CDC interface.

  • - Every time you install (plug in) a CDC device with a new VID/PID combination, windows will give it a comportnumber that was not used before, so the used number always increases. If you want you can change it to a more acceptable number using the windows 'device manager'. Portnumbers already taken can be found in the registry: See http://www.rosseeld.be/DRO/PIC/NextSerialPortNo.htm.

MSD devices:

  • The library assumes the SDMMC card is always present and writable. Also hot swap is not allowed.
  • The maximum card size supported is 4 GB.

Libraries:

- USB_CDC_Library_NA

- USB_HID_Library_NA

- USB_MSD_Library_NA

- USB_Library_Core_Constants_NA

- USB_Library_Core_NA

- USB_HID_Keyb_Library_NA (Ps2 keyboard to USB keyboard; Supports also the "Sleep", "Wake-up" and "Power" keys.)

The zipfile has the same content as the package.

Have Fun!

Version 1.1: Modified so that (changes to) values in "UsbProjectItems" like PID and VID are actually visible in the executable.

Important: the "USBxxx_ProjectItems.mpas" files have been changed!

-------------------------------------------------------------------------------------------------------------------------------------------------

18-03-2012: Removed an error in "USB_MSD_Library", calculation of the card capacity did not work correctly for cards of exactly 4 GB large. Still, the max size of the card supported here is 4 Gb.

-------------------------------------------------------------------------------------------------------------------------------------------------
29-03-2012: Added the P24 version of the libraries. No "keyboard" libraries yet however.
Have fun!

2012-06-08: The help section in the package and zip file has been updated.

------------------------------------------------------------------------------------------------------------------------------------------------
2012-11-12: The microBasic package(s) ha(s)(ve) been added.

Only the .mcl files are available as "library" files: they are copied from the mikroPascal version (the mP and mB .mcl files are compatible - luckely - ).

If you want to see some sources: look into the mP versions.

The example files are still in mP, not in mB. (I do not have an mB licence, so I can not compile them).

Some of the helpfiles are also still referring to mP, but all library "interfaces" are available in the mB language.

------------------------------------------------------------------------------------------------------------------------------------------------
2013-01-26:  Replaced "Delay_ms" and "Delay_us" by routines available in the Delays lib.
"Delay_ms" and "Delay_us" are inline routines and cannot be used in libraries if they are to be used without source (e.g. non Pascal compilers).

ALSO FROM THIS AUTHOR

Menus

Menu machine capable of handling text based menus. It only handles the logical behaviour of the menu(s), not their physical appearance e.g. on an LCD: the using project should still define the display or drawing procedures.

USB MSD Host Library

Library for making an USB host capable of reading and writing sectors from/to USB memory sticks ("USB drives" or "pen drives").To read/write actual files from/to the USB memory stick you need still e.g. a Fat16 or Fat32 library (see example).

LCD

* 2 (alternative) libs to drive LCD's (4 bits connections): - One lib specific for 2x16, - one more generic (upto 4 rows, 16-20 chars per row). * A library to drive LCD via I2c (PCF2116 based, 1 to 4 rows, 12 or 24 chars per row * A library to drive standard LCD's via I2c * A library to drive standard LCD's via SPI.
