NuMaker-PFM-M2351

The NuMaker-PFM-M2351 is fantastic board powered by a microcontroller from the ARM Cortex-M23 family.

The board combines a secure memory, one WiFi module (ESP8266EX ESP03), one NAU88L25 audio codec with a 3.5mm Mid-Mount SMD headphone jack and one Micro-SD socket placed on the back side of the board.

The ESP03 module can be programmed from the M2351’s UART3.

Arduino UNO Shield compatibility is by default. The pin strips are installed.

The MCU’s pin are fanout to 2.54mm 128 pins placeholder. No pinstrips included.

It seems that Nuvoton built the board as a IoT Device Reference Design.

The combination of the Crypto Accelerator and the Secure Flash Memory brings the board in the Secure IoT class. Therefore, you can build Secure OTA upgradeable firmware.

I was surprised seeing that Segger offers emWin as library completely free for some Nuvoton chips including the M2351. It may be cheaper than using Synergy for some displays.

Only after I changed the VCP Com DIP Switch I saw the board’s MBED flash drive showing in My Computer. In addition, I’ve enabled it in the MBED Online Compiler.

NuMaker-PFM-M2351

The Break-Away Programmer seems to be the usual Nu-Link-Me but is called ICE V3.0 – anyway is a very good SWD Debug/Programming Interface.

The ETM1 Trace Connector is connected on the Embedded Trace Macrocell Trace pins of Port.E and also SWD.

Eagle 9.2 Negative Solder Mask problem

Upgrading Eagle over 9.2,  a new strange thing happens. In the CAM settings, on every soldermask layer, appears a checked box named “Negative image”.

The results are… a borderless soldermask.

Eagle missing managed libraries

After a clean upgrade to Eagle 8.5.2 I couldn’t find the (new) managed libraries.

The user folder in “Documents” is fine with all the work and all the versions inside.

The answer seems to be that you have to re-import them and it makes some sense, but it would be better if it was some link to them in the Control Panel.

The fact that it is no auto-update is the best choice because you may have some file that wouldn’t need the updated library because you strangely placed something on the board.

The quick import procedure follows:

Open Library Manager > go to the Available panel > import by downloading all you need > check that all is fine in the In Use panel > close Library Manager.

Restart Eagle.

Sigfox – WiSOL SFM10R1 – SNOC Board

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:

[sourcecode language=”C”]

/*
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);

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).
