Beaglebone for ardupilot = beaglebone+BBBmini or beaglebone blue

I recently attracted by a new version of beaglebone, which is developed for robatic, and comes with debian+ arduipilot on it.

it's only 80USD,(well I paid 3000NTD with mouser)....for a fly control and on board computer, it is very cheap compare to pixhawk 2(which used discontinued CPU from Intel) and other ones with Pi...

There is also a very compact version of beagle bone which is even cheaper. packet bone...
but with no wifi, no display....it would be interesting few years age.


So, for beaglebone marrage with ardupilot I guess it started here:
https://github.com/mirkix/BBBMINI

BBBmini is the DIT cap, but you can also start with own PCB...

With my extra BB A6A on hand, this become very interesting for me...
Here are the interesting spec for me:
  • MPU-9250 IMU 9 x DOF( GY9250)
  • MS5611 barometer(GY-63 )
  • GPS
  • PRU firmware: 12 x PWM OUT with better than 1us accuracy, separate frequency for each channel. RC input capture with 5ns accuracy, can be used to capture PPM, S.BUS or spektrum satellite
The arrangement seems very reasonable to me:

BeagleBone parts used for BBBmini

  • Main CPU running Linux
  • PRU0 device driver for HC-SR04 ultrasonic rangefinder
  • PRU1 to generate 12 PWM signals and receive PPM, S.BUS or spektrum satellite input
  • Grove / I2C for communication to the status display, external compass or Laser rangefinder
  • GROVE / serial 2 for sensors like Laser Rangefinder
  • Serial 4 for telemetry radio
  • Serial 5 for GPS
  • ADC for voltage and current sensing
  • SPI1 for high speed data transfer from IMU and Baro sensor
  • SPI0 for high speed data transfer from second redundant IMU or other hardware
  • CAN for communication with ESCs and additional hardware
  • USB for WiFi and camera connection for life HD video transmission
  • Ethernet for communication on ground
 The connection is very well explained

Let's build something like this:

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
