  Hi, In this case you just use spi_bufTx[0] = 0; If you wanted e.g. SPI_MODE = 2 and LSBFIRST, you would use spi_bufTx[0] = 2 | 8; In other words, the first 2 bits define mode, the 3rd bit defines CS behavior, the 4th defines LSB etc. CS signal is controlled by operating system. You can only change its behavior by the 3rd bit as mentioned above. As for the delay function, I have turned it into a separate topic. Best regards, Jaroslav

  Hi Chris, thank you for reaching out. Yes, it is possible to interface with SX1509 via I2C using REXYGEN. However, it will require a bit of hand-coding. Have a look at function block called REXLANG and its function "OpenI2C" - https://www.rexygen.com/doc/PDF/ENGLISH/BRef_ENG.pdf#page=439 There are also some examples on I2C communication available - "0502 Generic I2C Communication" folder in Examples library (which is part of REXYGEN Studio) - these might help you to see how to implement the I2C communication according to your needs. Let us know about your progress. Regards, Tomas

  @stepan-ozana said in Connecting Racing Wheel to REXYGEN: It seems that the best idea is to replace the current board with a new one... Not sure if I understand. You did not mention any board in your original post. @stepan-ozana said in Connecting Racing Wheel to REXYGEN: It seems that the best idea is to replace the current board with a new one containing our own electronic circuit providing physical signals from the device (IRC, DI,...) and connect these signals to some I/O such as Arduino. This would work easily both under Windows or Raspbian, using REXDuino. Again I'm a little bit lost here. How are encoders and digital inputs related to a USB racing wheel mentioned in your original post? Are you planning to throw away the internal board inside the racing wheel and use only the sensors from the racing wheel? Please clarify. Regards, Jaroslav
