beaglebone with ubuntu and PyBBIO

I installed ubuntu 12.10 on beaglebone white without no problem.

and very happy to see that PyBBIO also have a installation guide on installing on ubuntu.
https://github.com/alexanderhiam/PyBBIO

To prevent problem, I use sudo su to be root. make sure we have correct internet connection. Get these first:
apt-get update && apt-get install curl gcc python-serial python-dev
after several check, it will ask for permission, type yes

it would take a while to install all these.
finally:

now use curl
#cd p curl http://python-distribute.org/distribute_setup.py | python
 Then you'll need to get the code:
# cd ~
# git clone git://github.com/alexanderhiam/PyBBIO.git
Now run the install script:
# cd PyBBIO
# python setup.py install
After few sh: 1:dtc : not found. it's installed

PyBBIO should now be installed correctly. Run the blink example to make sure all is well:
# cd examples
# python blink.py
when trying to run the example, it told me :
python-smbus module not found
so try:
apt-get install python-smbus

After installing python-smbus, tried again blink.py, I got these:


[ 2402.863765] bone-capemgr bone_capemgr.8: failed to load firmware 'PyBBIO-ADC-00A0.dtbo'

 After checking with creator, it seems that I don't have dtc on my board. following his instructions:
# cd /tmp/
# wget -c https://raw.github.com/RobertCNelson/tools/master/pkgs/dtc.sh 
# chmod +x dtc.sh 
# ./dtc.sh
re-install again PyBBIO, the blink.py works!!

in the installation, the PyBBIO dir is installed under root. Not easy to access, so I make a copy to hone/ubuntu using this command:

root@arm:~# cp -R ~/PyBBIO/ /home/ubuntu/


I used to use winSCP to transfer file to beaglebone. But I met permission issue in ubuntu when trying to copy files from local to bone.
The trick is that you can't use root in SCP nor SH, so need to set up a owner ship link between your login and  files. assume login as ubuntu and try to use /home/ubuntu:
Do this:

root@arm:/home# chown -R ubuntu:ubuntu /home/ubuntu

then we are able to move file form local to /home/ubuntu with winSCP

Heltec ESP32+OLED+Lora, hardware testing

圖片
you can easily find some good boards from china, but most of them lack of accurate document... Hrere is an example; https://hackaday.io/project/26991-esp32-board-wifi-lora-32 the board looks good with lora and a 128x64 OLED, but the IIC and reset connection is important, since pin can be muxing easily, so every board could be different. pinMode(16,OUTPUT);  digitalWrite(16, LOW); // set GPIO16 low to reset OLED  delay(50);  digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high  and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)  i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys  both work.  Display size is 128x64 There are discussions on these boards on TＴＮ as a LORA node..or maybee single ch gateway? Heltec has a git :  https://github.com/Heltec-Aaron-Lee And there is another copy call TTGO https://de.aliexpress.com/item/TTGO-LORA32-868-915-Mhz-SX1276-ESP32-Oled-display-Bluetooth-WIFI

micro SD card for ESP32, on lolin32 with OLED and heltec 32 lora oled

圖片
I have purchased 2 micro SD card holder for my esp project. First I would like to test with heltec esp32 lora oled module. this module uses: sck=05 MISO=19 MOSI=27 SS(lora)=18, then I assigned 21 for sd SS and there is a lib in esp32-arduino, which use SS default at 5 I took the example and use SD.begin(21), but I alway get the error: entry 0x40078a9c Card Mount Failed But I do saw once that it read out the sd card type and volume. Not sure it's the issue of lora sd card swithing, or it just can't work. The other esp32 card I have is an wemos esp32 oled, it did not leave me too much pins, I need to find out how to connect sd to it. But I have wemos D1 mini esp8266 on hand, and connect it as:  * The WeMos Micro SD Shield uses:  * D5, D6, D7, D8, 3V3 and G  *  * The shield uses SPI bus pins:  * D5 = CLK  * D6 = MISO  * D7 = MOSI  * D8 = CS It's not working with the example in the arduino IDE 1.8.5, which marked SD(esp8266), but it w

Install Network Time Protocol(NTP) on BeagleBone with Angstrom linux and set local time zone

Referenced from : http://cwraig.id.au/?p=513 1. Update your Package List opkg update 2. Get the ntp Package opkg install ntp ntpdate Update 2014/07/03 for the latest beaglebone image(2013-06-20) with kernel 3.8.12, after this installation,  system will add to service list, so only need to change time zone 3. Now we need to stop the ntpd service so we can request a manual update /etc/init.d/ntpd stop manual update ntpdate pool.ntp.org type in date, you should see the date is changing to current date and time, but the time zone is not corrected. The time zone info is contained in /etc/localtime , use this to remove it: rm /etc/localtime before link up our time zone, look into /usr/share/zoneinfo folder for your timezone. I did not find taiwan in asia, not plan to use hong_kong, but there is still: /usr/share/zoneinfo/Etc/GMT-8 now we make the link with ln command ln -s /usr/share/zoneinfo/Etc/GMT-8 /etc/localtime now type date again to check, should ha
