Hello folks, I have modified the SPI Master Loop example from the package so that I could communicate with the ADXL 345 accelerometer. I use the "spi_master_send_recv()" function to send in master's command. On my oscilloscope, I see the byte I send out from the MOSI, however I do not get any response from my accelerator's side. I checked the accelerometer's connection and they are fine. Am I using the wrote function for communication? Any ideas? Thank You in advance Milad.
