Installation of Python MySQL client on beaglebone angustrom

Referring to
http://www.hkcode.com/programming/417
http://sourceforge.net/projects/mysql-python/

http://dev.mysql.com/doc/connector-python/en/connector-python-installation.html

There are several connectors for different platform, win32, win64, debian, ubuntu...etc, each has file in 2 compression formats.ZIP or tar.

My beaglebone is on angustrom, no worry, there is a platform independent option

down load the tar file, and transfer to beaglebone with SCP, then un tar it, using python setup.py install to install it.
shell> tar xzf mysql-connector-python-VER.tar.gz
shell> cd mysql-connector-python-VER
shell> sudo python setup.py install




 installation complete with out error,
but  in python:
import mysql   no error
import mysql.connector failed with lot of error

Traceback (most recent call last):
  File "dates.py", line 38, in <module>
    import mysql.connector
  File "/usr/lib/python2.7/site-packages/mysql/connector/__init__.py", line 41, in <module>
    from .optionfiles import read_option_files

  File "/usr/lib/python2.7/site-packages/mysql/connector/fabric/connection.py", line 44, in <module>
    from xmlrpc.client import Fault, ServerProxy, Transport
ImportError: No module named xmlrpc.client

this web page explain some similar situation:
http://blog.immanuelnoel.com/2014/07/05/the-mysqlpython-connector-saga/

Using opke list | grep xmlrpc we found following related package:
python-xmlrpc - 2.7.3-r0.3.7 - python version 2.7.3-r0.3
xmlrpcpp - 1.9.48-r0.1 - xmlrpcpp version 1.9.48-r0
xmlrpcpp-dev - 1.9.48-r0.1 - xmlrpcpp version 1.9.48-r0 - Development files

seems the first one looks good, try it with
opkg install python-xmlrpc

But I got errors as following:
 * pkg_get_installed_files: Failed to open //var/lib/opkg/info/libxxf86dga1.list: No such file or directory.
 * pkg_get_installed_files: Failed to open //var/lib/opkg/info/kernel-module-virtio-console.list: No such file or directory.

Not sure what's that, but seems not terrible....So, I tried to import mysql.conector in python shell, this time, error has gone.

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-S...

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 m...

AIS0. understanding AIS NMEA 0183: How it's coded

For my boat tracking system, I found out that using AIS format seems to be a good idea, at least I don't have to worry about how to present boat data, since there are already plenty things for do this on mobile phone or PC. Here is what I read: http://catb.org/gpsd/AIVDM.html Looking into AIS NMEA0183, it has much more application then I think. Such as MOB device, epir, aid to navigation device...etc, all are included. it use the first few char to indicate the function: Table 1. AIS talker IDs !AB NMEA 4.0 Base AIS station !AD MMEA 4.0 Dependent AIS Base Station !AI Mobile AIS station !AN NMEA 4.0 Aid to Navigation AIS station !AR NMEA 4.0 AIS Receiving Station !AS NMEA 4.0 Limited Base Station !AT NMEA 4.0 AIS Transmitting Station !AX NMEA 4.0 Repeater AIS station !BS Base AIS station (deprecated in NMEA 4.0) !SA NMEA 4.0 Physical Shore AIS Station It can also be used between device on boat for message communication, AIVDO The...
