Re: ADIS16488 SPI connection using the mbed microcontroller LPC1768
Hi NevadaMark, You are right! I used the mbed MCU to supply the IMU at 3.3 V, while multimeter told me only 15 mA flowed into the IMU...It seems like the MCU could not provide such current.I changed to...

1. Yes, I think so. I thought it might be better to set up the sample rate before starting the transmission. NEVADAMARK: that is correct, but I don't think that you need a 500ms delay for every SPI...

Re: About tracking function.
Hi Tarzan,The ADP2164 tracking was tested in lab with ADP2164 eval board, 600KHZ and 1.2MHZ, Vin=5V, Vmaster=3.3V, the rising time for the master voltage = 8ms, Vslave=1.2V, Rtop=10k@1%, Rbot=10k@1%,...

How do we read/find the Silicon Rev of the 1452? When will Rev D be released? Thank you,TomC
View ArticleRe: ADIS16488 SPI connection using the mbed microcontroller LPC1768
No problem. I would say that getting a scope probe of the four signals, during a looped read of the PROD_ID register would be the next step for this. Based on your configuration, I would be concerned...
