I have 2 VL6180X Distance Sensors properly connected to a TCA9548A Multiplexer, however it only recognizes the Multiplexer itself and not the 2 sensors as you can see with the 0x70. Is there any way to configure the i2c adresses?

Luca's answer is better than this, though this should still work.

It doesn't work like that. You can't "see" the attached devices through the multiplexer.

Instead, you open the multiplexer and write a "control byte" to it, to tell it which device it should forward the following data to.

Try reinstalling the gstreamer packages like gstreamer1.0-plugins-good, gstreamer1.0-plugins-bad, gstreamer1.0-plugins-ugly and gstreamer1.0-libav.

Following packages will provide: gstreamer1.0-audiosink, gstreamer1.0-audiosource, gstreamer1.0-videosink, gstreamer1.0-videosource, gstreamer1.0-visualization

libav have elements for encoding 40+ formats (MPEG, DivX, MPEG4, AC3, DV, ...), decoding elements for decoding 90+ formats (AVI, MPEG, OGG, Matroska, ASF, ...).

I have been working through some i2c examples. Plugging it all together and I find that I need to install the i2c-tools package, then use raspi-config to enable the I2C system.

The wiringPi gpio command has a shortcut to the i2cdetect command and running it gives

The I2C bus allows multiple devices to be connected to your Raspberry Pi, each with a unique address, that can often be set by changing jumper settings on the module. It is very useful to be able to see which devices are connected to your Pi as a way of making sure everything is working.

To do this, it is worth running the following commands in the Terminal to install the i2c-tools utility.

Resetting I2C state using HAL in STM32L0 MCU

Asked 2018-Nov-28 at 11:12

I use I2C-tools to test firmware (HAL-based), I2C, STM32L0 MCU. When I send command to MCU (via i2cset utility), it sends an answer (received in i2cget). It works fine. If I call i2cget twice after single i2cset, it fails (which is expected behaviour). But if I execute i2cset after that error, then it also fails. So, the receive-transfer becomes broken (no callback is activated). How can it be fixed?

At the moment, HAL_I2C_Slave_Receive_IT() is called in HAL_I2C_SlaveTxCpltCallback(). HAL_I2C_SlaveRxCpltCallback() calls HAL_I2C_Slave_Transmit_IT(). Should I put HAL_I2C_Slave_Receive_IT() in two callbacks (receive/transmit related)?

...

ANSWER

Answered 2018-Nov-20 at 05:38

I don't know if you've solved this question. However, it is more accurate to define a flag that states that the HAL_I2C_SlaveTxCpltCallback, HAL_I2C_SlaveRxCpltCallback, and HAL_I2C_ErrorCallback functions have completed transfers or an error occurred.

maybe the following codes may be useful. You can reinit after making deinit.

I see you are using the KaRo TX6QP, too. I've managed to get eglfs with QT5 running on TX6DL/TX6S/TX6QP.

For the newer Kernels (e.g. mainline) you don't want the deprecated vivante-gpu-driver. Toss that out of your local.conf! You want (or need) the community-developed mesa-etnaviv driver for your Kernel and QP-Board.

Only three Steps are needed, since meta-karo already enabled mesa for all boards like you pasted from the meta-karo/conf/machine/include/tx-base.inc

1. Enable QT5-Mesa-Support

In your own meta-layer create the file recipes-qt5/qt5/qtbase_%.bbappend with the following content:

Install i2c-tools

There’s no configure script, so simply run "make" to build the tools, and "make install" to install them. You also can use "make uninstall" to remove all the files you installed. By default, files are installed in /usr/local but you can change this behavior by editing the Makefile file and setting prefix to wherever you want. You may change the C compiler and the compilation flags as well. Optionally, you can run "make strip" prior to "make install" if you want smaller binaries. However, be aware that this will prevent any further attempt to debug the programs. If you wish to include sub-directories that are not enabled by default, then just set them via the EXTRA make variable. For example, to build py-smbus, do: $ make EXTRA="py-smbus".

Support

The main tools have manual pages, which are installed by "make install". See these manual pages for command line interface details and tool specific information. The other tools come with simple text documentation, which isn’t installed.
