The following items are known issues in LabVIEW 2015 myRIO Toolkit sorted by Date.
ID | Known Issue | |||||
---|---|---|---|---|---|---|
387950 Return | I2C Shutdown VI Causes Bus to Show As Busy If There Are Multiple Masters The I2C Shutdown VI (used by the I2C Close) resets all the I2C registers to 0. However, if the user used the Keep Bus Busy? input of the Read and/or Write VIs of the I2C bus, the bus could still be in use and calling the Shutdown VI would leave the bus busy indefinitely. Workaround: N/A

406935 Return | Indicator Terminals in VIs on myRIO from Express VIs Look like Controls Indicator terminals from Express VIs look like controls Workaround: N/A
| |||||
510638 Return | I/O Monitor Returns Error -63040 and Fails to Connect When connecting with I/O monitor to the myRIO over a wireless network, the following error is thrown: Error -63040 occurred at niLvFpga_Open_myRIO-1900.vi. The reason for this is that the I/O Monitor cannot connect to the target over a wireless network. Workaround: Connect to target directly
| |||||
520023 Return | Encoder API Returns Error: -363005 When using a PWM and encoder on the same port of the myRIO, the encoder returns "Error: -363005: An invalid transition occurred in the quadrature encoder. Ensure that you have connected the hardware correctly and the encoder is not turning too fast." This can be for one of two reasons: 1. The target encoder phase changes too fast where the frequency exceeds 20MHz. 2. There is noise on the signal which needs debouncing. Workaround: Make sure the frequency of the encoder phase does not exceed 20MHz or add a debouncing function in front of the encoder input of the FPGA code.

530396 Return | myRIO Connection Diagram's Terminal Names in I/O Monitor Is Inconsistent The terminal names in I2C, SPI and UART Connection Diagram pages follow the rule:"Connector" / "Terminal". For example "A / TX", "B / TX". The names in AIO, DIO and PWM pages are inconsistent and only show "Terminal". Workaround: N/A
| |||||
530436 Return | myRIO Timer IRQ Example Throws Error "XNode is not executable" Opening the myRIO Timer IRQ example under a roboRIO throws error "XNode is not executable". The error is not descriptive. This error is thrown because of a broken subVI in the example. Workaround: Examine Error List to determine which subVI is broken.
| |||||
533568 Return | Removing the FPGA Chassis from LabVIEW Project Does Not Update FPGA Personality In a project with an FPGA chassis, you can select n samples mode from the I/O mode selector of certain VIs. When you remove the FPGA chassis, this option is still available and the VI will run without error. Workaround: Reload the project.
