[beagleboard] Re: BeagleBone Black touch input problem with ESD protection
I hope, you have solved the problem. If not, I'm hurry with the answer! 1) I had to connect a 10 inch resistive touchscreen, and go t the same issue. 2) The explanation is capacitance of the touch screen, which is a bit bigger then anything, the driver author had to deal with. BTW, quite surprising that they have not taken this to account, I'll explain in next point. 3) If you look in the ti_am335x_tsc driver, there is a charge phase, which load charge into touchscreen surfaces, which if not touched are like capacitor. This capacitor needs time to charge, so if the charging time is too short, the false touch is detected. Adding ESD protection increases capacitance! 4) The driver sets the charging time to 1 clock tick! That's, in my opinion a huge bug. Just ignorance of the topic knowledge. 5) In order to fix the issue, you need to recompile ti_am335x_tsc driver, before do two modifications: - linux-dev/KERNEL/inlcude/linux/mfd/ti_am335xtscadc.h : #define CHARGEDLY_OPENDLYCHARGEDLY_OPEN(*100*) also, I have increased sampling time, not sure if needed: #define STEPCONIG_SAMPLEDLY STEPDELAY_SMAPLE(*10*) - linux-dev/KERNEL/drivers/input/touchscreen/ti_am335x_tsc.c: (line around 276) z /= z2; - z/=z1; (another silly bug) Let me know if this helped. I have send some time before I have figure out that if cope configuration is loaded as overlayed, the driver shall be modproed after loading the cape config. This is not the case when cape configuration is discovered using EEPROM. So, I have also made this driver a module. Regards, Piotr.

The problem that we are having is that our ESD protection diodes seem to break the break the touch input. We are using a 4 wire touch interface on AN0, AN1, AN2, and AN3. The symptom we are seeing is that when the diode is connected to the touch interrupt seems to be triggered inconsistently. When checking the signals with a scope, it shows that the interrupt seems to work fine until an application that uses touch is run then it becomes inconsistent. This does not happen if the ESD diode is removed. The apps we are running are the Qt calibration and Qt touch test. Looking at the raw data from the touch device from within Linux on the BBB we see a steady stream of data before a touch app is run, then inconsistent data streams once a touch app is running AND after the app closes. Again this symptom does not happen with the diode removed. My question is 2 parts: 1)What could be happening that would make the touch interrupt inconsistent only when that diode is present AND one of these applications is run? 2) Do we really need additional ESD protection? Does Anyone have any experience with a BBB and a heavy usage resistive touch screen, that is not have additional ESD protection? In the two cape examples I looked at additional ESD protection is not used. This is the ESD part that we are using: http://www.comchiptech.com/cms/UserFiles/CPDT6-5V4U%20RevD364097.pdf Thanks Cyril -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Here's a quick step-by-step guide: 1. Press win+c on the keyboard to bring up the charms side bar (or move mouse to right top corner of the screen) 2. Click the Settings button. 3. Click the Change PC Settings at the bottom of the sidebar. 4. On screen that shows up, select the General option from the sidebar then scroll down the page that appears. 5. Click the Restart now button under the Advanced startup section. 6. You will momentarily see the restarting screen, then it will switch to a blue screen titled Choose an option 7. Click the Troubleshoot button. 8. Click Advanced options. 9. Click Startup Settings 10. Click Restart 11. You should then see a Startup Settings screen after your computer reboots. 12. Press 7 or F7 on your keyboard to Disable driver signature enforcement 13. Now Windows 8 will continue starting up. 14. Log-in as normal, and then run BONE_D64.exe again 15. Now you should see 4 warning dialogs about unsigned driver installation, click OK for all of them. Then you should be good to go!

I designed the software and hardware architecture, using ROS and Ubuntu, I use OpenCV a lot...on Lane and Traffic Sign detection modules. So my idea is that* could we use BeagleBoard Black to build a educational tiny version of that expensive research car and teach kids about autonomous driving staff?* *here are some example based on X86 framework: **http://blog.shixiong.org/?p=163 http://blog.shixiong.org/?p=163* We've done a little bit work at high schools and lecture hall back at china, it's well accepted.

[beagleboard] Beaglebone Black Ubuntu playing Music
since the standard Audio cape is not available, I purchased the DVID-02 cape which has HDMI and also the Audio TVL3106 chip which is the same as on the normal Audio cape. I was in anticipation of a nightmare configuring that all (since this cape is marked as incompatible with the BBB), I had low expectation of getting it working. But fortunately this job was done in a few hours and the Audio is working great ! This is how to get it running under Ubuntu: 1) install the BB-BONE-DVID-02 cape, switch on power and login via ssh (no HDMI !) 2) install the ALSA file: apt-get install alsa-base, alsa-utils 3) check if the TVL3106 can be accessed via I2C interface: i2cdetect -y -r 1 should show the chip at address 1b lets test if a write/read access is possible: write some data: i2cset -y 1 0x1b 2 3 read it back: i2cget -y 1 0x1b 2 this should return: 3 4) lets see if a sound chip is detected: aplay -l no sound is detected, thats ok and we will activate it in the next step. 5) prepare the uEnv.txt file go to the uboot directory and open the file uEnv.txt (Attention: this file is on the eMMC and also on SD Card, so be sure to open the file used for booting !). add/modify this line: optargs=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G,BB-BONE-DVID capemgr.enable_partno=BB-BONE-AUDI-01 this disables the HDMI (which is required, since the DVID cape is not compatoble with HDMI) and also disables the eMMC (since I am only using the SD card for Ubuntu, you may do that different) and (thats the trick): enables the BB-BONE-AUDI-01 Our board is not the BB-BONE-AUDI-01, but since both boards are using the same sound chip, we simple use the drivers for the BB-BONE-AUDI-01 board which works fine with our DVID-02 board. 6) reboot the BBB 7) after rebooting lets check the system log: dmesg this will show that Ubuntu found our DVID-02 board, but the installation failed. This is ok, since this board is not compatible with the BBB.

Re: [beagleboard] Re: which os
For what it is worth. I got my beaglebone black last year when they were first being sold to the public( we had two on pre-order). At the time I was working with the MSP430 launchpad, and talking back and forth with several people from this community about the BBB as we all were learning.

[beagleboard] Re: UART4 with RTS/CTS?
Interesting. My further investigations led me to the omap-serial driver, which sets Auto-CTS for the port only when a certain flag is set, and it appears to be never set, even with the latest version of the driver (I'm running kernel 3.12). I had to patch the driver to force that flag. Maybe I should go back and look at the 3.8 version to see if it's something that worked back then but then broke in the process of upgrading.

[beagleboard] Re: 4dcape-70t lcd and jitter issues
Alex, can you help me, I have the exact same issue. Could you upload your
image that fixes the issue with the 5 micro seconds delay. Are you running
debian or Ubuntu? I am not an expert on rebuilding the kernel to change
the ti_am335x_tsc.c.
Thanks

What I found is that Angstrom was counter productive when it came to do almost anything. NO documentation that I could find, and everything was like pulling teeth. Much like how many Linux distributions were 10+ years ago . . . Personally I prefer forward progress with any OS I do use. So after about a week of trying to no avail, I found Roberts compile from source instructions for Debian. Since then, I have never looked back. Everything is solid.

[beagleboard] Re: which os
Robert Nelson's Debian kernel is quite good. I've used it a number of times and it has all the features I needed. I've also used the machinekit build from Michael Haberler. It has a Xenomai-patched RT kernel and LinuxCNC on it, but works fine even if you don't need those particular features. It is by far the easiest install I've ever done on a Beagle system. Basically, you just run one script, it downloads all the files, builds the FS and puts it on an SD card. See : http://blog.machinekit.io/p/machinekit_16.html (It is just a customization pf the Robert Nelson kernel.)

[beagleboard] Using multiple TTL serial cameras with beagle bone. PLEASE help arduino sucks.
Hi all, I am working on my graduation project and need advice on using the beagle bone. I want to control up to 6 of these cameras: https://www.adafruit.com/products/397 to take a picture at the same time when my accelerometer detects free fall. I have been using the arduino UNO and have been able to take 2 pictures at the same time when free fall is detected, but now when i connect another camera the arduino can't handle it. Could this be done with the beagle bone? Is there a way to transfer my arduino code to beagle bone, it will be great since it has taken me a long time. Please help, i will greatly appreciate it. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Using multiple TTL serial cameras with beagle bone. PLEASE help arduino sucks.
Its going to be pretty difficult to get a 38,400 baud “take photo” command out to six cameras at once when you get a signal from your accelerometer. Without some real-time patches, Linux may have a response latency of 100 msec for a user-space program and with them 50 usec for an interrupt-driven kernel-mode driver. (That you get to write!) I think you could do it by using one of the PRUs to bitbang that command to six different GPIOs at the same time. Then the PRU would have to bitbang the six Rx GPIOs (since BBB doesn’t have enough UARTs) to capture the images. Or maybe each camera will store its image until you send it a “download” command? Then you could use three GPIO outputs to control an 8-way MUX chip, so you could receive the images one at a time from each camera using one of the UARTs. You could also try using a little bit of programmable logic (like a CPLD) so you could use some GPIO pins to select the camera destination for one UART’s output. Then you could select the destination as “all cameras” when you send the “take photo” command, and each individual camera when you send a “download” command.

It is even worse, that nobody seems to care about this problem. Contrary to that, the Raspberry PI's standard kernel has PREEMPT activacted from the very beginning. I have tested Robert Nelsons kernel 3.8.13-r9 ( https://github.com/beagleboard/kernel/tree/3.8-rt). It does not have PREEMPT_RT activated by default. When doing so, it does not boot.

Meanwhile there's an rt17 patch set ( https://www.kernel.org/pub/linux/kernel/projects/rt/3.8/). Did anybody give this a try?
