GM Ports:
Your ports for GM are not consistant with topic.asp?TOPIC_ID=298
GPIO1: ?? J1 Contact Closure Detect ?? GPIO2: ?? What is this tied to ?? // LED2: ?? GPIO3: ?? What is this tied to ?? // LED1: ?? LED1: LEDOUT0 GPIO20 LED2: LEDOUT1 GPIO25 LED3: LEDOUT2 GPIO26 IOA1: UCB_IO0 UCB1200 IOA2: UCB_IO1 UCB1200 IOA3: UCB_IO2 UCB1200 IOA4: UCB_IO3 UCB1200 IOA5: UCB_IO4 UCB1200 IOB1: UCB_IO5 UCB1200 IOB2: UCB_IO6 UCB1200 IOB3: UCB_IO7 UCB1200 IOB4: UCB_IO8 UCB1200 IOB5: UCB_IO9 UCB1200 AIN1: ANIN0 UCB1200 AIN2: ANIN1 UCB1200 AIN3: ANIN2 UCB1200 AIN4: ANIN3 UCB1200
Aren't ports AIN1: - AIN4: read only ??

- The J1 contact closure is event driven in the newer builds of CE. See the following Topic for more information:
topic.asp?TOPIC_ID=155
- For the Graphics Master, GPI2: and GPI3: Drive GPIOs 25 and 26 respectively as shown in the CE Developer's Guide addendum table. LED2: and LED1: also drive these same GPIOs (on the Graphics Master). See the following Topic for more information:
topic.asp?TOPIC_ID=205
- The UCB1200 Digital IOs listed in topic.asp?TOPIC_ID=298 are correct. The Graphics Master manual lists UCB_IO5-9 in reverse order (ascending by pin instead of signal name) and that may be causing some confusion.
- AIN1: through AIN4: are analog inputs and you are correct that they only have meaning when read (though writing to them will not cause an error). The PortTest application has them in the Port list anticipating a future version that will allow both input from and output to the ports.

Do you have the port test sample in C++? |

We do not have a C++ version of PortTest. For a basic test application, you can modify the Heartbeat sample application by changing the port name from "LED1:" to the port you wish to test.

Rev 2 Feature Addition
We've added the ability to change the high/low duration and duty cycle of the port toggle so you can now use PortTest as a rudimentary square-wave function generator.

Rev 3 Feature Addition
We've added support for the Bitsy Plus ports, most notably the EIO1: digital ports. |
