Sigfox – WiSOL SFM10R1 – SNOC Board

WiSOL SFM10R1: a cheap Sigfox Module made by WiSOL available as devkit from SNOC/Yadom.

The only strange thing with this WiSOL module is that it responds with “ERROR: parse error” at the usual “AT” command.

A simple test code that sends some data to the network respecting the constraints:


/*
 Sigfox Module Test Unit
 */

int button = 2;
int led = 13;

void setup() {
// WiSOL works on 9600:
  Serial.begin(9600);
// some basic LED debug info
  pinMode(button, INPUT);
  pinMode(led, OUTPUT);
// more to go for the receive function
// add ",1" for the downlink frame 
}

void loop() {
   int buttonState = digitalRead(button);
      if (buttonState == LOW){
        Serial.println("AT$SF=000011110000");
        // some basic LED debug info
        digitalWrite(led, HIGH);
        delay(800);
        digitalWrite(led, LOW);
        delay(200);
        digitalWrite(led, HIGH);
        delay(800);
        digitalWrite(led, LOW);
        delay(200);
        // obey to the max 1 msg every 10 min rule 
        delay(600000);
  }
else {
        // basic LED debug info
        digitalWrite(led, HIGH);
        delay(50);
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);
        delay(50);
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);
        delay(50);
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);
        delay(50);
        digitalWrite(led, LOW);
        delay(1000);
        
 
  delay(40000);

The EFM32 Development Kit – Gecko, G890F128

EFM32 Development Kit

The EFM32 Development Kit features the EFM32G890F128 MCU (128 kB flash + 16 kB RAM) and is one of the best kits designed for low power device development.

The Advanced Energy Monitoring (AEM) system is practically a very good power monitor and logger, embedded in the Development Kit. Some other kits are doing this in the IDE, but to have it with a display onboard is awesome.

A large spectrum of techniques, from using different low power modes to switch-off peripherals can be tested directly and all with one kit.

The on-board Segger J-Link enables debugging.

The OOB configuration enables that the EFM32 can be programmed with many demo programs selected with the 320×240 TFT Display GUI and the power consumption can be monitored on the same TFT after programming.

Some features:

  • Single ended and differential ADC inputs on BNC connectors
  • Line-in and Line-out stereo audio amplifier with 3.5 jacks
  • IrDA, RS232
  • MicroSD card reader
  • 4MB 70ns PSRAM+ 16MB 90ns NOR Flash + 2Kb I2C EEPROM
  • Accelerometer and LDR

javapath javaw unspecified error

Few words about this annoying error:

javapath javaw unspecified error The cause is the C:\ProgramData\Oracle\Java\javapath symlink system that isn’t fully working.

The quick solution is to add the full path to your own jre’s bin folder (Ex.: C:\Program Files (x86)\Java\jre1.x.y_z\bin) to the PATH (Windows System Variable).

Testing that is all ok can be made also by running “java -version”.

If other java bin is missing it can be restored from the no-extension zip file from C:\ProgramData\Oracle\Java\installcache .

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

TI Link: http://www.ti.com/tool/430boost-cc110l

Anaren Link: https://www.anaren.com/air/cc110l-air-module-boosterpack-embedded-antenna-module-anaren

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).

Fake DS18B20

Fake DS18B20 found

Bought a small lot of DS18B20 from a small Chinese Online Shop…

None of them working. Behavior like a shorted component.

Testing them with a small component analyzer (ESR meter, large screen version) resulted as NPN transistors. Beware.

Playing with ESP8266 modules and IoT

ESP8266 as IoT device

Reviewing the Exosite Murano Platform for a IoT solution, I started to build a new board based on ESP8266 powered ESP-12E module.

Tools used: Autotrax DEX aka DEXPCB and DFM now!

 

Arduino ESP support installation instructions:

Start Arduino and open Preferences window.
Enter the following link into “Additional Board Manager URLs” field.:

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Start the Boards Manager, update and select the ESP support package.
Install and use a USB to Serial adapter to program the board.

The AVR Studio 4 way:

Connect. Select HVSP. Go.

THE AtmelStudio 7 way:

View > Available Atmel Tools shows only the JTAGICE mkII and the Simulator. Go to Tools > Add target. Or write STK in the upper-right box called “Quick Launch” and the Add target dialog appears. (I tried also PICkit, but it’s still not there)

COTS Test: Wireless Charger

This gallery contains 8 photos.

COTS Test series – Wireless Power – part 1

Testing this pair of  Wireless Power Transmitter + Receiver I noticed that the output current measured was 10% of the stated value. I start to peel off the receiver and try to measure what that coil (not litzwire) receives.

Transmitter Coil: 3uH

Receiver Coil: 3uH without shield

WE SKEDD Line

The SKEDD line of PCB connectors by WE

One alternative solution for a press-fit PCB connector is the WE Patented SKEDD contact. A great solution seems to be the 3 row shrouded locking connector concept announced by WE.

WE SKEDD’s wire to board, SKW connector designed for white goods can sustain a 400v/20A power transfer to a 1.6mm PCB. Mating cycles 5.

Datasheet here.

The Component to board series can simply eliminate the need for a socket. Some uses: relays, fuses and leds.
