  1. Using the Waveforms program, I am able to set the polarity of the UART signal. However, I do not have a function call to set polarity programmatically using LabVIEW. Is there such a function call, and if so, where can I find it? Thanks! Respectfully, David Johnson
  2. @attila This is exactly what I needed! Thank you! I have already run the test sequence and it appears that the issue has been fully resolved. Respectfully, David Johnson
  3. @attila Will there be a new .h file? I'm trying to add the function to the LabVIEW library. Thank you!
  4. @attila Thank you! I am installing now, and will be testing this afternoon. Respectfully, David Johnson
  5. Good Afternoon! I am trying to use the Digital Discovery as an I2C master with clock stretching enabled. The device I am talking to will hold SCL low while it processes an interrupt, and release SCL when it is ready to receive again. I am running into an issue where the device will hold SCL low for about 12s. During this time, the LabVIEW function call has already closed even though the required data has not been transmitted/received. How long will the Digital Discovery wait for the clock/data if clock stretching is enabled? Thank you! Respectfully, David Johnson
  6. @AndrewHolzer Thank you for your response. Is there any chance that this might change in the future? Respectfully, David Johnson
  7. I am using the Digital Discovery to communicate using CAN. When listening, I am only able to receive one message because the Digital Discovery does not send an ACK bit at the end of the message. Is there a way to send the ACK bit at the end of a CAN message? I think the question should be: Does the Digital Discovery support Standard Mode, not just Listen Mode? Thanks! Respectfully, David Johnson
  8. @JColvin thank you for responding. At this time, I'm waiting for a Molex part to come in that appears to have the correct size including the key. While I will need to create the cabling myself, I would prefer that to having an unkeyed connector that the end user could connect backwards. If Digilent is looking for any product suggestions, I would recommend the cable with two keyed connectors. Thanks! Respectfully, David Johnson
  9. I have a Digital Discovery that has been working wonderfully for me, and I am looking to implement it in a test fixture. While the 2x6 to Fly Lead connector has been perfect for the design, test, and debug process, I am looking for a connector-to-connector version that I can use for the test fixture. I would like to used keyed connectors so that the operator cannot accidently misconnect the device to the test card. Do you have a connector-to-connector version already assembled that I can purchase? Is there a part number for the connector? Thank you! Respectfully, David
  10. @attila Thank you! I have installed the version in Windows and everything is working.
  11. The first issue I am running into is that I do not see the TX data or clock when I use an oscilloscope on the SDA and SCL lines when clock stretching is disabled. As soon as I enable clock stretching, I see the clock and data signals. It appears that as soon as I disable clock stretching, I disable I2C completely. I posted images of the scope response on Sunday. The first image shows the address byte being transmitted with no ACK. The second image shows that the SDA and SCL lines do not change state at all. The first image was taken with clock stretching enabled, while the second image w
  12. @attila, I am still running into the issue, using the python script, where I disable clock stretching and I do not see any toggling on the I2C lines at all. I have configured DIO ports 24 (SCL) and 25 (SDA) (ports 0 and 1 for the script). With clock stretching enabled, I see the write and read commands transmitted on the lines. With clock stretching disabled, nothing shows up on the scope. The scope is configured to trigger on the first falling edge of the SDA line. I am including the python test script along with the command window responses, one with stretching enabled and one with
