  11. pcDuino Acadia I will start off by actually loading the OS onto the Acadia’s eMMC storage. Following this tutorial. First download the firmware updating software from here and unzip it on to your windows PC. With the Acadia turned off make sure all of the boot configuration switches are set to the OFF position. OFF-OFF-OFF-OFF-OFF-OFF-OFF-OFF In the download folder of the firmware updater you should find a file named “cfg.ini”. Open this file in a text editor. There should be a line that says, “name=Acadia-eMMC”. If not, make the change and save it. Run the MfgTool2.exe program. Connect the Acadia OTG port to a usb port on the PC and power it up. A few drivers should be automatically installed. The MfgTool2 app should say, “HID-compliant device”, in one of the top text boxes when its ready. Click “start”. This will take some time to complete and it should say, “Done”, when finished. Click stop and exit. We should be done with this program for now. Power down the Acadia and change the configuration switches to boot from eMMC. ON-ON-OFF-ON-OFF-ON-ON-OFF Attach SATA cable and power cable to Acadia. Power it up and it should boot from the eMMC. Open Disk Utility and create a root partition and format it. In my case it was /dev/sda1. I then used dd to copy the root system to the hdd with this command below. ? 1 >dd if=/dev/mmcbkl0p1 of=/dev/sda1 bs=1M conv=noerror,sync This took some time as well. Once completed, unmount the partition using disk utility. In a terminal window we are now going to convert the ext3 partition to ext4 by using these commands. ? 1 2 3 >sudo tune2fs -O extents,uninit_bg /dev/sda1 >sudo e2fsck -f /dev/sda1 These will take a little while as well. There were errors found on mine and they were corrected. Next we must modify the u-boot environment variable to have /dev/sda1 mounted as root. To do this we need to connect to the Acadia debug port. For this I used PuTTY and created a serial connection to that port with settings of 115200,N,8,1. From this terminal window I issue the “reboot now” command. When the Acadia comes back up it will pause for a few seconds and ask you to hit enter to exit the boot routine. I will admit that it took me a couple of tries before I got it. At the u-boot prompt type the command. ? 1 u-boot>pri You should see a listing of the boot up script. Somewhere in there you should see a line that says something similar to, “bootargs_mmc=……”. We are going to replace that line only changing the “root=” variable. Yours may vary depending on video settings, etc. Duplicate your line and change it to read, “root=/dev/sda1”. So my command would be something like below. ? 1 u-boot>setenv bootarg_mmc 'setenv bootargs ${bootargs} root=/dev/sda1 rootwait fec_mac=${ethaddr} video=mxcfb0:dev=hdmi,19200x1080M@60,if=RGB24,bpp=32 fbmem=28M' Notice the single quotes. They are required. Execute the command to save it. ? 1 u-boot>saveenv Use the pri command again and look at the bootargs_mmc variable just to make sure. It will be at the bottom of the list now. ? 1 u-boot>pri Power down the Acadia. Then power it back up. If all went well you should now have root filesystem on the hdd.
  12. The MAX6675 performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI™-compatible, read-only format.

  13. This LinkSprite PWM shield adds 27 independent PWM channels to Arduino or pcDuino by using a dedicated PWM generation MCU: STM32F103C8T6. All the PWM pins of STM32 can support up to 5V. The total number of PWM channels is 27. The duty cycle can be adjusted. The channel number is labeled on the shield as below: The four jump headers next to pwm 27 are for the selection of communication ports, such as SPI, UART and I2C. Right now, the sample code we provide has only SPI interface. The external power supply is specified to be between 7V to 24V. The three pins header SWD is for firmware download to STM32. The PWM shield has 27 PWM channels in total. Among these 27 channels, the 16 channels implemented by hardware in STM32 are 2, 3, 4, 7, 8, 9, 10, 11, 17, 18, 19, 20, 22, 23, 24 ,25, and are divided into four groups. The channels within the same group has same output frequency, but with different adjustable duty cycles. Channels 2, 3, 4, and 7 are in the same group, channels 8, 9, 10, 11 are in the same group, 17, 18, 19, 20 are in the same group, and 22, 23, 24, 25 are in the same group. The other channels are implemented by software, and each channel has its own frequency, but the higher the frequencies, the worse the resolution. The communication protocol is as following: /****************************Message format*************************************** index Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 mean START CMD INDEX VALUE_L VALUE_H CHECK_SUM ********************************************************************************/ The command has 6 bytes in total: The command starts with a first byte “0x87”. The second byte is the commands that need to be executed. The supported one are following: #define CMD_SET_ON_OFF 0x01 (Turn on or off) #define CMD_SET_POLARITY 0x02 (Polarity of the signal) #define CMD_SET_FREQ 0x03 (Frequency of the signal) #define CMD_SET_DUTY 0x04 (Duty cycle of the signal) Description of the parameters: 1. The range of the duty cycle is between 0-10000, which corresponds to 0-100%. 2. The precision of the channels implemented by software is 5uS, and the ones implemented by hardware is 0.5uS.
  14. NFC( Near Field Communication Technology) by RFID( Radio-frequency identification) evolved, and now this technology has been widely used in mobile devices, the mobile with NFC-enabled can act as access cards, transportation cards, credit cards and so on, this to say, it makes the mobile devices more widely. Hardware Preparation Hardware Connect Program code Test result 1 x Arduino UNO 1 x NFC PN532 Shield 1 x NFC label 1. Put the NFC label close to the sensing area and you will see the return news from the serial area. If read the correct label, the serial will print out Found 1 tags The back number of read card # is the corresponding ID number.
  15. BLE4.0 Shield is an arduino shield which based on TICC2541. The AT instruction set integrated by BLE4.0 module is simple and effective to use, and greatly shorten your developing period. Based on the bluetooth standard specification, Bluetooth Low Energy (BLE) technology allows BLE4.0 to further reduce peak power to half, comparing with traditional Bluetooth devices. The single-mode chip of Blue tooth4.0 (BLE) enables to work for a long time (up to several months even years), powered by single button battery. Instead, traditional Bluetooth technology generally asks for at least two AA batteries, meanwhile at most works for several days or weeks. The main disadvantage of previous blue tooth version is extremely low startup speed. For example, Blue tooth 2.1 spends 4s to startup, but it’s only takes 3 ms for Blue tooth 4.0 to startup. If comparing Blue tooth 2.1 to a basic “feature phone”, then, Blue tooth 4.0 would be a “smart phone”.
