Today is sunny. ^_^... Let's write something about MicroPython PyBoard. In my test, I'm using a PyBv1.1, which embeddes a STM32F405RG microcontroller.

Overview

1. Contents In PyBoard

After connecting PyBv1.1 via USB cable, you will possibly see a folder prompt on the screen as follows:

Current Contents In PYBv1.1
PYBv1.1 Properties

2. Test Out picocom

Thanks for using picocom

3. Test Out screen

➜  ~ screen /dev/ttyACM0

Then you will see a micropython working console as:

>>>

It looks there is NO prompt after login via screen. That's why I did 1+1 as a test whenever logging in by screen.

Now, let's press Ctrl+A then Ctrl+d to quit screen.

4. VERY Important

The code typed in the working console from either picocom or screen is corresponding to main.py in PYBFLASH.

Test

1. LED and Switch

The code is directly copied from MicroPython's homepage.

while True:

    else:
        x = max(0,x-1)
    led.intensity(x)
    pyb.delay(30)

Press the USR switch and take a look what's going on? ^_^ Interesting, isn't it?

2. Log of Accelerometer's Readings

Let's try out MicroPython's Example Code : Accelerometer Log with trivial modification.

# log the accelerometer values to a .csv-file on the SD-card

import pyb

accel = pyb.Accel()                                 # create object of accelerometer
blue = pyb.LED(4)                                   # create object of blue LED

log = open('.log.csv', 'w')                      # open file to write data - /sd/ is the SD-card, /flash/ the internal memory
blue.on()                                           # turn on blue LED

for i in range(100):                                # do 100 times (if the board is connected via USB, you can't write longer because the PC tries to open the filesystem which messes up your file.)
        t = pyb.millis()                            # get time since reset
        x, y, z = accel.filtered_xyz()              # get acceleration data
        log.write('{},{},{},{}\n'.format(t,x,y,z))  # write data to file

log.close()                                         # close file
blue.off()                                          # turn off LED

Just press the RST switch, the above piece of code will automatically run once, and the onboard accelerator's reading will be logged in file log.csv. In my test, 100 readings are logged as:

Flash Micropython Onto Pyboard

1. Checkout Micropython Source Code

Let's FIRST download the NEWEST micropython release. In my case, the MOST up-to-date release is 1.11. (Do NOT** use the git version** from https://github.com/micropython/micropython.git ).

2. Build Micropython For PYBV11

We'll strictly follow ports/stm32/README.md to build Micropython.

Then we enter subfolder ports/stm32. for further building.

3. Load MicroPython on a Microcontroller Board

The above ERROR message is telling that our board is NOT in the DFU mode yet. Therefore, according to the blog How to Load MicroPython on a Microcontroller Board, we need to make sure P1 (DFU) and 3V3 pin are connected together before flashing.

Note: Before connecting P1 (DFU) and 3V3 pin, make sure power is disconnected from the pyboard.

Now, let's try it again:

Skill 1 - How to apply color for words in Markdown?

Solution

Please refer to https://stackoverflow.com/questions/35465557/how-to-apply-color-in-markdown.

1
Some Markdown text with <span style="color:blue">some *blue* text</span>.

Test

Please refer to the following line in our yesterday's blog NVidia Jetson Nano - 1. The code is as follows:

Skill 3 Embed Jupyter Notebook into Hexo Post

Posted on Edited on In ,

I got the Intel Wireless-AC 9260 today, and a proper 128G micro SD card, finally... Let's try out Jetson Nano.

PART A: Install JetPack onto Jetson Nano

Let's simply use the command dd to have JetPack installed onto the micro SD card as follows:

➜  JetPack sudo dd bs=4M if=jetson-nano-sd-r32.1.1-2019-05-31.img of=/dev/mmcblk0 conv=fsync

PART B: Boot Into Jetson Nano and Test it Out

1. First Boot

It seems GUI is a must for Jetson Nano's FIRST BOOT, which is ignored in this blog.

2. SSH into Jetson Nano

For now, Jetson Nano is wired connected onto the Internet. And it seems Intel Wireless-AC 9260 is NOT working properly with Jetson Nano yet. Details can be found at https://devtalk.nvidia.com/default/topic/1050449/jetson-nano/intel-9260-wifi-on-jetson-nano-jetbot

By following our previous blog Build GCC, we should be able to CROSS-BUILD GCC for various ARM architectures. Today, we are building GCC 9.1.0 for Hikey 970, which is of aarch64 architecture. (More details about aarch64 can be found on ARM architecture )

Posted on Edited on In ,

Today, let's try to build the MOST RECENT GCC 9.1. We strictly follow the TERRIFIC blog How to Build a GCC Cross-Compiler with trivial modifications for my x86_64 desktop instead of aarch64 cross compile.

Preparations

Packages Required on HOST

Some packages are required to install on the host computer, including: * g++ * make * gawk * bison * flex * expect * gnat etc.

Get ALL Packages for Building GCC

A wget-list.txt file is provided to download ALL required packages up-to-date. After having downloaded this single text file, the UNIQUE command to download all files is as follows:

1
➜  gcc ✗ wget -i wget-list.txt

You can of course download the files one by one. All concerned files are listed below: * https://gnu.freemirror.org/gnu/binutils/binutils-2.32.tar.gz * https://gnu.freemirror.org/gnu//gcc/gcc-9.1.0/gcc-9.1.0.tar.gz * https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.1.12.tar.gz * https://ftp.gnu.org/glibc/glibc-2.29.tar.xz * https://ftp.gnu.org/mpfr/mpfr-4.0.2.tar.xz * https://ftp.gnu.org/gmp/gmp-6.1.2.tar.xz * https://ftp.gnu.org/mpc/mpc-1.1.0.tar.gz * ftp://gcc.gnu.org/pub/gcc/infrastructure/isl-0.18.tar.bz2 * ftp://gcc.gnu.org/pub/gcc/infrastructure/cloog-0.18.1.tar.gz

Then, we extract all .tar files in whatever way you prefer.

Posted on Edited on In ,

According to our previous blog Install Armbian Ubuntu Desktop Nightly Built onto Orange Pi 3, Wifi module of Orange Pi 3 with Armbian nightly built for Orange Pi 3 does NOT function well. Therefore, today, we resort back to the Ubuntu Desktop distro from Orange Pi's official website.

PART A: Install Ubuntu Desktop from Official Orange Pi Website onto Orange Pi 3

1. Download Ubuntu Desktop for Orange Pi 3 from Official Orange Pi Website

We FIRST go visiting Orange Pi's official website http://www.orangepi.org/downloadresources/ and find the Ubuntu Desktop distro for Orange Pi 3.

After OrangePi_3_xenial_desktop_linux4.9_v1.3.img.tar.gz has been downloaded, we had it extracted as follows:

3
➜  orangepi tar xvf OrangePi_3_xenial_desktop_linux4.9_v1.3.img.tar.gz 
OrangePi_3_xenial_desktop_linux4.9_v1.3.img
OrangePi_3_xenial_desktop_linux4.9_v1.3.img.md5sum

2. Install Orange Pi's Official Ubuntu Desktop for Orange Pi 3

Exactly the same as in our previous blog Install Armbian Ubuntu Desktop with the Newest Supported Mainline Linux Kernel onto Orange Pi Plus 2, we have the TF card formatted and dd the system into it.

950+0 records out
3984588800 bytes (4.0 GB, 3.7 GiB) copied, 170.284 s, 23.4 MB/s

PART B: Boot Into Orange Pi 3, Enable SSH, Update & Upgrade, Locale Configuration, Network Configuration

Different from our previous blog Install Armbian Ubuntu Desktop With Kernel 5.0 onto Banana Pi M3, SSH service on Orange Pi's Official Ubuntu Desktop for Orange Pi 3 is NOT enabled by default. Therefore, we've got to enable SSH during out FIRST boot.

1. Boot into Orange Pi 3

The overview of Official Orange Pi's Ubuntu Desktop for Orange Pi 3 looks as:

3. Enable SSH

Auto Start SSH Service After Booting

After having successfully enabled SSH, you are able to login Orange Pi 3 remotely. Well, you may still need to figure out how to:

  • setup Wifi for Orange Pi 3, which is pretty simple with Ubuntu Desktop GUI
  • further setup static IP addresses in your router for both Wifi and Wired connections

Since I've already updated/upgraded all packages, it'll tell you from terminal that All packages are up to date.. BTW, it seems Orange Pi is a team from TsingHua Universiity?
