I am wondering how a very long range line-of-sight (LOS) broadband link can be maintained using directional tracking antenna at both ends, i.e. onboard and ground station. I am interested in RSSI (received signal strength indicator) instead of GPS based tracking, specifically with 15 to 20dBi...
I was wondering if there is some example code for the digital control of a 4 switch non-inverting buck-boost converter available to start with... preferably implemented using Arduino Uno or Arduino Mega.
I have modified several Analog Devices IMU drivers for PX4 project to run in 8-bit SPI mode instead of 16-bit, since the Raspberry Pi does not support 16-bit SPI transfer under Linux.
Interestingly the IMU sensor works fine with Arduino Uno SPI with a similar 8-bit transfer mode (see the...
Exactly! But I am not using any level shifter in this case and connected the SPI according to Fig. 5 of https://www.analog.com/media/en/technical-documentation/application-notes/an-1041.pdf
According to the following document (Fig. 5) the 5V sensor can be directly connected to 3.3V Raspberry Pi SPI.

However, still struggling to get it work, with no success. I have captured the SPI waveforms and...

There is a following foot note on page 4 for LOGIC INPUTS and DIGITAL OUTPUTS, which I don't understand.
The digital I/O signals are driven by an internal 3.3 V supply and the inputs are 5 V tolerant.
Please have a look at the following link of the datasheet of the sensor and suggest if there will be an issue directly connecting 3.3V master side MOSI, SCLK, and CS to the sensor? I think the V_IH specification is on page 4.

Is it possible to directly connecting Raspberry Pi MOSI, SCLK, and CS and, 5V to 3.3V voltage divider on MISO??
Would the Raspberry Pi 3 MOSI, SCLK, and CS pins tolerate 5V? I know they are driving and not driven by 5V, but still tolerable and works?
I need to connect a 5V sensor to Raspberry Pi 3.3V SPI using a conventional level translator on all 4 SPI lines (MOSI, MISO, SCLK and ~CS) but it does not seem to work. The schematic of the level shifter is as under.
I have tested the same 5V sensor on Arduino Uno SPI and it works fine.

It worked with 100 kHz speed, 0x19 address and inserting appropriate delays between the send and receive data according to the datasheet.
Thanks, Klaus and FenTrac for the help.
