emControl IO—Digital IOs
- General input and output
- Variable IO level voltage
- Target power supply
- UART with up to 115.2 kBaud
The emControl I/O module comes with an easy to use software API. It allows reading and writing of the I/O pins separately or for the whole connector. In addition the module provides an UART interface with up to 115.200 bits/s.
The software API supports two modes: direct mode in which the commands are directly executed and a buffered mode. In that mode a sequence of commands can be programmed will be executed on software trigger. The software supports the usage of several parallel modules.
Connecting emControl I/O to the PC
Conneting to a Windows host
- Connect emControl I/O to a PC running Windows using the USB cable.
- Open the sample project.
- Set up the serial number of your device in the main.cpp.
- Compile the sample project.
- Start the sample project.
Connect emControl I/O to a Linux host
- Connect the emControl I/O with the USB Cable to the host.
- Alter the serial number in the main.cpp to your emControl I/O.
- Compile the sample application using the makefile.
- Copy the rules file (99-emControl.rules) to the /etc/udev/rules.d folder.
- Run the sample application.
Example Applications
USB connect test
- Device Under Test (DUT) is connected behind a emControl I/O board to the host.
- The host test program can switch on and off the DUT usint the emControl I/O board.
- The host test program can simulate user actions like attach or detach the module to the host.
- After the specified time the host test program can check if the enumeration has taken place and was successful.
Rapid prototyping: testing a new display
- The developers can use a host PC simulation to .
- The new hardware piece like a display can be connected to host PC before the original embedded hardware is available.
