Linux boot log from a cheap Hi3518 chinese IP Camera

We bought this IP Camera from Alibaba:

http://www.alibaba.com/product-detail/Low-Lux-1-3-Megapixel-HD_1498636656.html

Although the camera module they sent me is not exactly the same from this link’s picture it appears a new version. Doing some debug I discovered that the serial TX/RX pins are connected to pins 15 and 16 respectively from a 20-pin flexible cable connector:

camera

Connecting these pins to USB/Serial adapter and configuring a serial console terminal to 115200 8n1 I got this bootloader/kernel log:

Dicas para usinar/fresar aluminio num CNC

Estes links foram postados na lista reprapbr, como achei muito útil e interessante, resolvi salva-los aqui para que possam servir para outras pessoas.

Alumínio não é tudo igual, como algumas pessoas podem pensar. Existem vários tipo de ligas e cada uma adequada para um tipo de uso. Neste site você encontra a sugestão de qual tipo de alumínio é melhor para ser usinado usando um CNC:

Neste outro link você encontrará 10 dicas para usinar alumínio, estas dicas são genéricas, não levam em consideração qual o tipo de alumínio será usinado:

Interpreting the ELM327 OBD-II response

To read the Speed of your car you need to enter this command on OBD-II dongle devices:

> 010D

Then the module will respond something like that:

7E8 03 41 0D 4A 4A

The first value (7E8) is the ECU address in the CAN Bus (11 bits at 500k bauds).

The second value (03) is the amount of data bytes returned.

The third value (41) is the acknowledge of command received (01 + 40), this 40 is a constant added to all commands.

The forth value (0D) is just a copy of OBD PID that we are interested.

The fifth value (4A) is the data of speed that we want to know. This value is in hexadecimal, like all OBD-II data. In our case 0x4A = 74, it means 74 Km/h.

The sixth is just a copy of fifth, you can modify the configuration to avoid this copy if you want.

Using obdsim + usbserial + bluetooth module to emulate a real OBD-II

I need to implement a solution for a customer who needs to read some data from vehicles. Then instead of spend time testing it directly in the car, I decided to use an emulator.

OBDSIM is the right tool to do it on Linux/Windows, but the bluetooth SPP/RFCOMM profile to emulate real device was not working.

Then I decided to test a crazy idea. I connected a USB/Serial adapter to a Bluetooth serial dongle and paired it to Android. It worked like a charm.

I used a bluetooth module HC-06 (JY-MCU BT_BOARD V1.06) connected to a USB/Serial Cypress CP2102. My initial idea was to connect this way:

USB/Serial           BT Module
+5V                  VCC
GND                  GND
RXD                  TXD
TXD                  RXD

But the USB/Serial was unable to supply enough current to HC-06 module, then I used an external 5V power supply to feed the bluetooth module. I unsolder the wire from +5V of USB/Serial and connected to +V of external power supply and soldered the -V to GND as a common ground for USB/Serial and HC-06.

Then just started obdsim passing the USB/Serial device file (ttyUSB0) to be used as real port:

$ obdsim -g gui_fltk -t /dev/ttyUSB0

In the Android smartphone I paired to bluetooth HC-06 device (default password is 0000) and used to Torque OBD-II Android application to read data from obdsim. I added these gauges on Torque: rpm, Throttle, Cooland, MAF and Speed. These are the same gauges I can control in the FLTK GUI of obdsim.

The final setup of my “solution” is depicted in this picture:

Flashing NuttX on Viewtool STM32F107 board

Yesterday I received a Viewtool STM32F107 board V1.2 from ebay:
www.ebay.com/itm/250893674758?_trksid=p2055119.m1438.l2649

Unfortunately this board doesn’t have a built-in programmer (well, I didn’t test DFU mode), then I decided to use the st-link v2 programmer:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=400581128094

It was easy to connect the st-link programmer to viewtool because it use SWD interface. Only three wires were needed:

ST-Link V2    Viewtool JTAG connector
GND ---------------- GND
CLK ---------------- TCK
IO  ---------------- TMS

Now it is time to compile NuttX to Viewtool board, it is also very easy because NuttX has native support to this board. Then I just configure NuttX profile to viewtool/nsh and selected the Build option to “Raw binary” (default is Intel HEX format).

The compilation was fine and generated the nuttx.bin file. Then I just use this procedure to flash NuttX on viewtool: https://acassis.wordpress.com/2014/01/13/using-a-stm32f4discovery-board-to-flash-stm32f100rb-from-stm32vldiscovery/

Important: You need to remove the USB/Serial module from USART1 otherwise it will interfere in the SWD initialization. Keep the board powered only by miniUSB connector, then openocd wil get control correctly using st-link_v2 interface.
