ADSmartIO: Manual and Firmware Releases
The ADSmartIO component of ADS StrongARM products extends the power of the processor with flexible, autonomous I/O control. Download the driver specifications and libraries to begin your development today.
- Pronunciation: [ay dee ESS smart eye OH]
- Programmer's reference for all products (PDF 91k)
CE Libraries
All CE builds include DLLs for using ADSmartIO functions. See the posts below for eVC libraries that link the functions or wrap them in a C++ class for use in your application. We also have sample applications for C# and eVB for examples of how to get started.
The static libraries (.LIB) formerly on this page are out of date and no longer supported by ADS. If you need them for your older system, request them by email by clicking one of the following links: GC, GC+, Bitsy, GMaster.
Linux ADSmartIO
Linux and CE use the same function calls to control ADSmartIO functions. For further information about how to use the ADSmartIO features with Linux, see the Linux sample code and Linux ADSmartIO FAQ.
Firmware Releases
You can update the ADSmartIO firmware on your system using the firmware from the following links. For WinCE, use the AVRPROG.EXE application as described below. For Linux, see the reprogramming information at topic 472.
Note that for products shipped beginning Fall 2003, a new programming app is needed. (details)
AGX and VGX
GC Plus and GCX
BitsyX, BitsyXb
GMaster (90026)
Bitsy (1021D)
Bitsy Plus (1010B)
Some OS releases do not support in-system programming of the ADSmartIO. For those you will need the Kanda AVRUSB programmer and a product-specific adapter to connect to the board. Contact ADS if you need an adapter for programming.

Erratum: Port B pin numbering error
Page 11 - SmartIO Configurations table
Port B incorrectly shows five assigned pins, including pin 10. Pin 10 is a UCB1200 I/O.
The Port B portion of the table should read:
| | Option 1 | Option 2 | Option 3 | J2 Pin |
| PB0 | Digital IO B0 | Digital IO B0 | Digital IO B0 | 12 | | PB1 | Digital IO B1 | Digital IO B1 | Digital IO B1 | 14 | | PB2 | Digital IO B2 | Digital IO B2 | Digital IO B2 | 16 | | PB3 | Digital IO B3 | Digital IO B3 | Digital IO B3 | 18 |

#software_pull-ups
Addendum: Software pull-ups
The ADSmartIO controller has a feature not documented in the manual: You can enable pull-up resistors through software.
This allows you, for example, to connect a switch (or open collector output) between the input line and ground without the use of external pull-up resistors. This significantly simplifies hardware design.
To use ADSmartIO pull-ups:- Configure the digital I/O lines as inputs (write 0's to those bits using SIOInitDDRX())
- Write a "1" with SIOWritePortX() to bits that need the pull-up enabled
- Write a "0" to bits that need the pull-up disabled
The pull-up voltage is 3.3V (the ADSmartIO supply voltage).
Pull-ups resistors are disabled by default.

Erratum: PB4 not available to users
The ADSmartIO manual mistakenly shows that port B4 is available for use in applications as "Digital IO B4". This is a mistake. It is used by the ADSmartIO controller for internal purposes and should not be used in applications.

Addendum: More Graphics Master ports available
The Graphics Master has all the same ports available as the Graphics Client Plus, plus a few more. Ports that are the same include PA0-7, PB0-3, PC0-7 and PD0-1.
On the Graphics Master, the SA1111 handles the PS2 keyboard. This frees up PD2-6 for use as digital I/Os. They are available on J20.

#Bitsy_ADSmartIO
Addendum: Bitsy ADSmartIO Ports
The following ADSmartIO ports are available on the Bitsy:
PA0 COL0
PA1 COL1
PA2 COL2
PA3 COL3
.
PC0 ROW0
PC1 ROW1
PC2 ROW2
PC3 ROW3
PC4 ROW4
.
PC6 SMTI02
PC7 SMTI03
On the Bitsy, PD0 and PD1 are used for Vee control and temperature measurement. Though they are available on the Bitsy connectors, the current revision of the Bitsy ADSmartIO protects PD0 and PD1 from being written to.
PC6 and PC7 are not available on Rev 1 connector boards mated to Rev C Bitsy systems.

#using_keypad
Addendum: ADSmartIO Keypad Scanning
The SIOSetKeyPadSize() function description includes information about how to use a keypad. Here are additional details:
- The ROWn signals are configured as inputs with software pull-ups enabled.
- The COLn signals are configured as outputs and set to "1"(high).
- The keypad scanner sets successive column outputs to "0"(low), then looks for a "0" on one of the ROWn inputs.
- The scanner performs debouncing by re-reading the pressed key after a delay.
- The scanner is set up for one key to be pressed at a time. Multiple key presses will give an undefined result.
- The returned key code is (COL + 8*ROW), where ROW and COL are between 0 and 7.
Here's an example of how you would connect to a 3x3 keypad. Note the location of the software pullups.

#SIOSetSSPTimeout
Addendum: SIOSetSSPTimeout()
The SIOSetSSPTimeout() function determines how long an ADSmartIO function will block waiting for a response before returning an error code. Use this function to set how long to wait for a keypad press from SIOReadKeypad().
The prototype for the function is:
BOOL SIOSetSSPTimeout(ULONG Timeout);
where Timeout is in milliseconds.

| Can anyone confirm that the [Windows CE] Keybddr.dll is able to receive fuction calls from various application without a problem. I belive the term is reentrant. In other words, Can I have multiple applications call on a SIOReadPortA() function at the same time without running into problems? |

Multi-threaded Access to ADSmartIO
Hi Jason. Generally, the ADSmartIO code isn't reentrant. The Graphics Master ADSmartIO firmware and CE drivers have been updated recently to better handle calls from different threads. Drivers for other products may be updated in the future.
For robustness in your application, use a mutex or single-threaded access to manage your ADSmartIO requests. Otherwise calls from one thread might receive the results from another. |

#active-high_backlight
Active-High Backlight Control
The ADSmartIO uses active-low logic to control the backlight. That is, the ADSmartIO sets the BacklightOnOff signal to zero volts to turn the backlight on.
The following ADSmartIO builds use active-high logic. These builds were made for specific customers and are offered "as-is". Contact ADS Sales if your application requires a build that isn't available on this site.
An alternate use for these builds is if you want the power-up state of your backlight to be "off".

#performance
How fast are ADSmartIOs?
ADSmartIOs are generally intended for low-speed digital I/O and A/D. Data rates are fundamentally limited by the SPI communications channel between the processor and the ADSmartIO controller.
Here are the results of a recent test(*):SIOWritePortA or C(), 2.5 ms
SIOReadPortA or C(), 5.5 ms
SIOAnalogConversion(), 14.3 ms If your application requires high-speed digital I/Os, consider using the processor's digital I/Os, which don't have the communications overhead of the ADSmartIO (eg. see this topic). For highest performance, newer ADS products expose the CF bus, which can drive 16-bits of data at MHz speeds.
The maximum rate at which the AVR microcontroller can make an A/D conversion is every 12.5ms(80Hz).
(*) Test methodology: (Win CE app #20-xxxx) Each function was called 100 times consecutively. Average times are shown. Repeatability was high (+/-1%). Thread priority improved performance when other applications were running; values shown are with priority=0(max). Tested on GC Plus CE build 3.39 with ADSmartIO release 4017J.
20-11302 (ZIP) is a similar test that illustrates the conversion speeds of the ADSmartIO and UCB1200 A/Ds. Sample test results included illustrate that ADSmartIO A/Ds take about 14ms while UCB1200 A/Ds convert in about 0.3ms.
Edited by akidder 1-Nov-2002: Add link to test 20-1130.
Edited by akidder 20-Feb-2003: Add note about A/D conversion rate.
Edited by akidder 4-Apr-2003: Clarify that test was made with CE.
Edited by akidder 2-Aug-2003: Correct max frequency of A/D conversions to 80 Hz |

#ADSmartIO_dynamic_link
Dynamic Linking to the ADSmartIO DLLs (Windows CE)
The following eVC library dynamically links to the ADSmartIO DLL built into your platform. This library makes all ADSmartIO functions available to your application.
When you use the loader function included in this library, your ADSmartIO applications will be portable across all ADS platforms.

Changing Modes ("Options")
ADSmartIO firmware does not currently support dynamically switching between modes ("Options"). You must reset the ADSmartIO controller (usually by power-cycling) before changing to another mode.
The intent of the ADSmartIO design is that an embedded application will select the mode that matches the hardware connected, and that an application will only use one mode in its operation. |

#SIOSelectOption
Addendum: SIOSelectOption() not used on newer products
Newer ADS products have eliminated the need to use the SIOSelectOption() function, as the "options" somewhat limited the flexibility of the Atmel AVR I/Os. In products like the Bitsy Plus...- You can choose to have any pin be a digital input or output.
- Configure as inputs any Port A lines you wish to use as A/Ds. Be careful not to write a "1" to those bits, or you will enable the software pull-ups, which will affect your A/D signal.
- Ports selected by SIOSetKeypadSize() for use in keypad scanning can't be used for other purposes.
Calling SIOSelectOption() on these products will not have any effect, so older code is still compatible. |

#ATmega
Change in ADSmartIO Microcontroller: New Reprogramming App Required
Based on the recommendations of Atmel and our suppliers, we have changed the processor we use for ADSmartIO functionality on our products. Beginning with production runs in Fall 2003, ADS products transitioned from the Atmel AT90LS4434/8535 AVR parts to the ATmega family.
This change is transparent to applications and users of our products, as the core logic of the microcontroller didn't change. The only difference that users will note is that the in-system programming application no longer works with the new ATmega parts.
For Windows CE applications, see topic 1360 for the updated application. For Linux, see topic topic 472.

#reprogramming_in_WinCE
Windows CE AVRProg.exe Usage Instructions
Here are the programming instructions that were formerly included with each SmartIO release for reprogramming the SmartIO in Windows CE:
____________________
To upgrade the SmartIO firmware, follow these instructions:
1. Place the attached SMARTIO.BIN firmware file in the root folder of your CE device (ie. My Computer folder, at the same level as the Windows folder)
2. (Optional but strongly recommended) Set up the debug port tom onitor information about the status of the reprogramming.
3. Run the AVRPROG application
- If you are running the backlight from the your CE device, the display may go dark while the firmware is being reprogrammed.
- Programming takes up to 60 seconds
4. When complete, you should see a message displayed on the screen
5. (Optional) Reset the system to confirm the version of the SmartIO code that was actually installed. See text at the top of the document for expected debug port output. Note that the part type may vary between 4434 and 8535.
Troubleshooting:
The debug port provides more details about error codes than what is displayed on the LCD panel.
