Anaren LR09A

Anaren LR09A

The LR09A (A110LR09A) is a module built by Anaren Inc based on the sub-1 GHz RF transceiver – CC110L.

For evaluation is really easy to use the AIR Boosterpack

Using one pcb for stand-alone operation:

On the PCB there are some DNP components that are needed only for the stand-alone configuration.

  • one simple S1 push switch is used for pairing
  • two 47k pull-up resistors – one 0603 as R1 and one at P1.3 (I don’t know why I can’t see the footprint)
  • one 0603 LED as D1 and his 0603 limiting resistor R2
  • some 0.1uF decoupling caps

The MSP430G2553 needs to be programmed with the Anaren Firmware and configured with ATC – BoosterStack Lite as Sensor (Application State Selector).

TI CC3200 Launchpad – Quick Guide

TI-Exosite_CC3200A quick start guide to the CC3200 Launchpad:

Out Of the Box feeling

OOB application is very nice, you can connect to the AP without security and then you go to the 192.168.1.1 (or http://mysimplelink.net , as indicated by TI, if you think that’s shorter…). Here answers a small webserver that serves some (uncompressed) html files that  are a frontend to the configuration settings and also some nice demo programs and documentation.

More

Prerequisites:

Uniflash Simplelink: The flashing tool for the CC3200 http://www.ti.com/tool/uniflash

Jumper on SOP pins.

Uniflash wiki UG: http://processors.wiki.ti.com/index.php/CC31xx_%26_CC32xx_UniFlash

The CC3200 SDK + Service pack can be downloaded from here: http://www.ti.com/tool/cc3200sdk

Some IoT provider, I chose Exosite. Step by step account and usage documentation: https://support.exosite.com/hc/en-us/articles/202271424–CC3200-Wi-Fi-Launchpad

Shortlist:

Create a TI Exosite account https://ti.exosite.com

Add the device mac to the Exosite Dashboard

Flash the Exosite firmware on the CC3200 Launchpad

Enjoy!

Issues:
  • Profiles won’t be saved if the WPA2 key is too long. Even in OOB Fw.
  • Flashing without format won’t work.
  • Formatting various sizes (1MB, 2MB, 4MB, 8MB, 16MB  from Format Options window that comes after you push Format button) leads to strange results, my CC3200 Launchpad has responded well only on 4MB. Even the OOB was unable to restore the board without reformatting to 4MB.
  • I noticed that sometimes the CC3200LP communication enters in a strange mode, appearing offline to Exosite and the Dashboard is showing up some negative temperatures. The LP responds to ping, the uptime displayed by the http server is ok. Only a power cycle reset solves it…
Fastest way:
  1. Select COM port, put jumper on SOP pins, verify using Get Version (Reset push-button required).
  2. Formatted 4MB, nothing else checked.
  3. Apllied Service Pack Update.
  4. Flash the desired firmware.
  5. Remove SOP jumper. Put on the AP Jumper (VCC-P58)
  6. Connect to the AP without security
  7. Create a Profile with the local WiFi configuration (SSID, Key) and give it a index number. Save.
  8. Reset the board and wait the boot and connect sequence.
If you try to restore the OOB firmware, you get the original status by opening with Uniflash the out_of_box.ucf that comes in the CC3200SDK\cc3200-sdk\example\out_of_box\html folder.

Late edit:
  1. The problem was due to a high current thing, and brings the CC+Exosite FW  in the same boat with the Fluke 233  rev.1 @36mA in active mode…
  2. Preproduction Silicon doesn’t support SDK > 1.1
  3. Exosite’s guide for those who want to switch from Portals to Murano https://community.exosite.com/t/how-to-use-murano-in-my-own-cc3200-board/316/2
Even later:
  1. Connection issues are mainly because of the SOP (Sense On Power) Jumpers. Flashing/Programming can be done with 100 configuration, that means only one jumper, placed on position labeled 2.
  2. Using the programmed configuration will be done removing that SOP jumper
  3. Uniflash 4.0 can’t be used for CC3200, use instead the old 3.4.x version
  4. The COM Port speed setting: 921600

Energia, something between TI Launchpad series and Arduino/Wiring

Energia, something between TI Launchpad series and Arduino/Wiring

http://energia.nu/ is awebsite that bring Energia, a Wiring/Arduino IDE fork designed to ease the Ti Launchpad series integration into the maker/hobbyist world.

In conjuction with the low price of the Launchpads and the growing number of the Boosterpacks I think that TI hits it big!

Energia, between TI Launchpad and Arduino

Energia, between TI Launchpad and Arduino

Right now it supports the following LaunchPads: LaunchPad MSP430G (MSP430G2231, MSP430G2452 and MSP430G2553), FRAM Launchpad aka. FraunchPad (MSP-EXP430FR5739), Stellaris LaunchPad (EK-LM4F120XL ).

No C2000 for now.

The Stellaris LaunchPad from Texas Instruments, ARM development made easy.

The Stellaris Launchpad – a good and cheap ARM tool.

The pre-registered Stellaris Launchpad version was 4.5USD only, actual version is 12.99 USD.

This fantastic board features two LX4F120H5QR (ARM Cortex M4 with floating point), one as ICD and one as target, two user switches and one RGB Led driven by 3 transistors.

The “target” clock oscillator is build with Y1 32k768 and Y2 16MHz Osc.

The power jumper allows you to measure the target’s power consumption.

Other great thing is the presence of the two gender stackable headers which allows any header connector/cable combination, the Piccolo C2000 had only dual-side (stackable) male headers.

C2000 Launchpad celcius to celsius change

Testing the C2000 Launchpad:

After loading the default application sourced by TI Control Suite 3.0.3 into TI Code Composer 5 I changed the “Celcius” spelling into “Celsius”. May be someone’s trademark?

The C2000 Launchpad works great, the XDS100 included is instantly detected by the Code Composer and works as debugger in the same time with the USB/Serial console.

Another great tool from TI!
