a111_pulsed_radar_breakout's Issues

Calibration error using SDK 1.4

Opening new issue per advice, really appreciate the assistance. If you haven't seen this error before, I'm leaning towards my soldering job :(

I'm not sure if I should ask this here or over at the sparkfun forums, but after pulling this update and building, I seem to get calibration errors. The sensor initializes correctly it seems,

Here is some example output:

make error using spark example code on A1 SDK 1.3.9

I found the example code provided by Sparkfun was written for an earlier A1 SDK version (1.3.5) and the newer version (1.3.9) might have changed enough that it breaks the build. After I type "make" n terminal, I met this problem.

pi@raspberrypi:~/a111/evk_service_linux_armv7l_xc111_r4a_xr111-3_r1c_a111_r2c $ make
Linking sparkx_envelope_service_example

rule/makefile_build_example_service_envelope_rpi_sparkx.inc:10: recipe for target 'out/sparkx_envelope_service_example' failed
make: *** [out/sparkx_envelope_service_example] Error 1

I cannot find the directory shown in the error message.
/home/anders/repos/sw-main/acconeer/sensor/sensor_driver/acc_sensor_driver.c

Does someone successfully build the program and get the radar data?

Coordinates system of A111

Now I obtained outputs like this
Distance detector: Reflections: 5. Seq. nr: 424. (200-700 mm): 648 mm (137), 658 mm (250), 665 mm (255), 676 mm (209), 686 mm (65).

But since I don't know the coordinates system of A111, I don't know the meaning of the amplitude of the reflection. What is x-axis? What is y-axis? Where is the origin? The amplitude should be an angle between an axis and the line connecting the origin and the object.

Please Update for SDK 1.4.0

The code doesn't build with the most recent SDK:

pi@raspberrypi:~/evk_service_linux_armv7l_xc111_r4a_xr111-3_r1c_a111_r2c $ make
    Compiling acc_board_rpi_sparkx.c

I tried setting up the new gpio_t param myself, and I end up hard-locking the Pi.

Please Update for SDK 1.6.0

It seems that Acc published a new SDK version (1.6). With these files I get a compilation error (multiple "conflicting types for"). Unfortunatly I don’t have enought experience to modify them myself. Does anyone have a workig version of the files for the SDK 1.6?

About Pi Zero W...

Hello everyone
I have a question I want to ask.
Can this module work on Pi Zero W?

make error using spark example code on A1 SDK 1.3.11

I am getting this error when I run make:
make: *** No rule to make target 'out/example_service_envelope.o', needed by 'out/sparkx_envelope_service_example'. Stop.

Using the following sdk:
acconeer_evk_service_linux_armv7l_xc111_r4a_xr111-3_r1c_a111_r2c_v1_3_11

The build only fails if I add the A111_Pulsed_Radar_Breakout software addon.
Does anyone have SDK 1.3.9? Or know what I need to do to fix this?

Clarify that raspberry pi SPI needs to be enabled

I'm going through the tutorial now, and I was stuck when the Acconeer binaries didn't seem to be working. After a while, I discovered that SPI was diabled by default in Raspbian. It's easy to enable via "Raspberry" -> Preferences -> Raspberry Pi Configuration -> Interfaces, and clicking "enable" under the "SPI" line

Missing libacc_local_server.a

Hey guys, first of all thanks for the work on this!
I've followed the tutorial but after copying the rules/source contents to the proper folders in the SDK and running make, I get the following:

make: *** No rule to make target 'libacc_local_server.a', needed by 'out/sparkx_envelope_service_example'. Stop.

After comparing the original rules with the sparkfun rules, I see that you are expecting the following lib files:

libacc_local_server.a
libacc_message_driver_dummy.a

However, these are not present in the lib folder of the SDK.

Does this mean they have removed some files from the lib folder in the SDK by which the Sparkfun tutorial is no longer compliant? I received acconeer_evk_service_linux_armv7l_xc111_r4a_xr111-3_r1c_a111_r2c_v1_3_6.zip from Acconeer, while the tutorial mentions v1_3_5?
If I leave the sparkfun files out (rules/source), the SDK compiles without problems.

Any help would be appreciated!
