Name Date Short description
USB HOST libraries 2017-02-16 new USB Host libraries. USB MSD Host library and USB HID host library, only for PIC24 for now.

MSD: Library for making an USB host capable of reading and writing sectors from/to USB memory sticks. To read/write actual files from/to the USB memory stick, you still need e.g. a Fat16 or Fat32 library. The lib software assumes the USB memory stick is powered from an external source.

HID: This is a library for making an USB host capable of reading and writing 64 byte packets from/to generic USB HID devices. At this moment only a version for PIC24 is available.

Adapted Fat32 driver for the mE Fat32 library
Example of usage of the MSD host library with the mE Fat32 library
Example of usage of the HID Host library

MSD Host Documentation.
HID Host Documentation.

For the library software, documentation and example projects (packagefiles or zipfiles), see above.
USB units, New Architecture (NA). 2019-04-12 Set of USB units, permits creating composite USB devices.
For example projects and documentation, see the .mpkg or the .zip files.

Note: This set of NA units will exist next to the ones already presented below. The latter are meant to create simple USB (in the sense of "non composite") devices.

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.

  • CDC devices: 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

  • CDC Devices: 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 NextSerialPortNo.

  • MSD devices: The library assumes the SDMMC card is always present and writable. Also hot swap is not allowed.

For the library software, documentation and example projects (packagefiles or zipfiles), see above.

Tool: TestCDC.zip, a PC CDC application (Delphi).
USB units, original architecture (OA). 2019-04-12
  • HID
    USB "HID" library.
    Creates a non composite USB HID device. Permits to read data from and write data to USB devices using the "HID" protocol (no driver at PC side required).
    For example projects and documentation, see the .mpkg or the .zip files

  • CDC
    USB "CDC" library.
    Creates a non composite USB CDC device. Permits to read data from and write data to USB devices using the CDC protocol (makes the USB device look like a serial port).
    2010-03-01: Capable of working with usbser.sys under windows (means Hyperterminal can be used), and also works under Linux (Thanks Rainer!).
    For example projects and documentation, see the .mpkg or the .zip files
    PP2 = PingPong version of the library.

    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.
    • CDC devices: 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).
    • CDC Devices: 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 NextSerialPortNo.

  • CDC Twin
    USB "CDC Twin" library.
    Only for PIC for the moment.
    Same as above, but creates 2 virtual com ports on the PC.

    Important remark:
    Make sure there is an entry in usbser.inf for both cdc devices, e.g.
    %DESCRIPTION%=DriverInstall, USB\VID_1234&PID_2000&MI_00
    %DESCRIPTION%=DriverInstall, USB\VID_1234&PID_2000&MI_01

  • MSD
    USB "MSD" library.
    Creates a non composite USB MSD device. Makes the PIC (equipped with an SD/MMC card) look like an external drive to the PC (no driver at PC side required). For example projects and documentation, see the .mpkg or the .zip files.

    Important remarks:
    • The library assumes the SDMMC card is always present and writable. Also hot swap is not allowed.

For the library software, documentation and example projects (packagefiles or zipfiles), see above.

Tool: TestCDC.zip, a PC CDC application (Delphi).

Button Utilities 2012-11-22 This library provides two “button” related types of behaviour that often are wanted in a project:
  • Every time a button is pushed, something must happen once, or
  • A button must be “autorepeating”: something must happen when the button is pushed and after that something must happen every xxx milliseconds as long the button is pushed.
  • A button must have 2 different functions: one function when the key is pressed for a short time, another function when the key is pressed for a long time.

Name Date Short description
RTOS

 2015-08-14 Real Time Operating System.

For PIC32 only.

Documentation

RTOS can give you the potential opportunity to squeeze more from your PIC than you might expect from your current single threaded application. For example, how often do your programs spend time polling for an input or an event. If you could have the Operating System tell you when an event has taken place you could use that polling time to do other things. This applies equally well to delays. By using RTOS you can write programs which appears to be doing many things all apparently at the time. Some of this can be achieved in a single threaded program by using interrupts but by using RTOS together with interrupts you will have be able to quickly develop responsive applications which are easy to maintain.

RTOS supports the following features:
  • Task priorities
  • Pre-emptive sheduling: a (low priority) task will be interrupted by a task with higher priority
  • Automatic task switching every 10 timerticks, under interrupt (can be disabled).
  • Round Robin scheduling within tasks of the same priority.
  • Tasks can have local variables of which the values are preserved between task invocations
  • Unconditional yielding to the RTOS Scheduler
  • Timed yielding to the RTOS Scheduler (i.e. “delay” performed by the Scheduler)
  • Binary semaphores
  • Counting semaphores
  • Waiting for semaphores with or without timeout
  • Clearing semaphores
  • Starting and stopping tasks
  • Starting tasks with an initial delay
  • Signaling semaphores from within an Interrupt Service Routine
  • An “Idle” procedure can be called when no task is running (none is eligible for running)

Acknowledgement: The specification of RTOS is derived from CRTOS which in turn was derived from PRTOS which was written by John Barrat in PDS Basic.
Thanks John!

The library has the same functionality as the parallel version of mE, with one small extension: it can handle more keys pressed (the status of the 16 keys of the keypad in one word).
Connection Diagram for a 4x4 keypad. If there are less keypad columns or rows, then the free PCF8574 line(s) should be left unconnected.

TempSensors:
DS18(B/S)20
and LM35 		2015-07-18 The basic functions for the DS18(B/S)20 (digital temperature sensor), including string output, ready to display.
The routine(s) to drive the DS18(B/S)20 from parasite power.
Routine to convert a temperature read from a DS18B20 to a string (to e.g. display on an LCD) is also present.
An example of its usage (with more than one DS18(S)20 on the same OW bus) can be found in Ow.mpas. A more extended usage example is Thermostaat.zip . Other usage examples: Thermostat 001, Thermostat 003.

The basic functions for the LM35. Two functions to convert an ADC reading into a "Temperature", one procedure to make a displayable string out of the "Temperature". The "Temperature" value has a 0.5 degrees centigrade resolution. One of the conversion routines is very "cheap" regarding code size usage, but can only be used for 5V ADCVref and 10 bits of ADC resolution (only P16 and P18).
No float calculations used, only integer ones: limited code size usage.
