I got this board a lot time ago and finally have a little time to complete it. MCU and usb-ttl work correctly, all power suppliers are fine, board fits the enclosure. Let's move forward

Finally solved a lot of problems and checked a lot of mistakes. But now the first version of this device works almost properly :trollface:

I will make a small report in the description asap

Hello, i'm making some progress; received the components this week. Unfortunately it doesn't work... yet For now i have SanityCheck failure in to logs. I'm afraid my soldering of all these little components is not good. I tested with a multimeter the 4 pins and i have continuity on one of them but maybe not the others so i guess i will have to try remelting all these small regulators ???

I think you can just set the I2C pins in MyBoardNRF5.h without remapping the pins in MyBoardNRF5.cpp. Look in MyBoardNRF5.h, under the Wire Interfaces section. Set SDL and SCA to 30 and 31 as appropriate for your board.

@mr_red I have a zipped snapshot of all the 3d step/wrl models that I used to build my projects so far. It was quite some work to gather them all and align with the footprints using the kicad stepup tools. It's not complete - still needs some more work:simple_smile: but it should help you or anyone else to get started into MCAD integration using FreeCAD and kicad stepup tools. Maybe it's not very easy to start when using free tools but hey they are "FREE" so we cannot ask for more. But the nice thing is that once you get used it will be really easy to do your stuff and to go forward. Oh and FreeCAD can be so powerful after you learn it - I was really amazed what you can do with it(it has it's quirks and downsides but once you master it - oh, well...). There's also: https://www.onshape.com/ - pretty powerful this one too and it has more advanced features than FreeCAD but the downside is that it's a cloud based solution: it's free for public documents but you never know when they will go to paid accounts only so yeah...I don't really like the idea to depend on something that it's hosted and the application is not on my PC along with the documents that I create with it. Cloud solutions have their flexibility but you're locked and you depend entirely on that hosted service. Ok, enough talking...I uploaded the zip file here: http://www.mediafire.com/file/kzh1l9uo40cpj1u/kicad_stepup_packages.zip

Lovely work. Are you proposing to sell the boards? SMD looks too hard.

When you read the data sheet correctly you can see, that the distance between the pins is different for a AA and AAA battery holder. That`s why I was asking if somebody can recommend a holder that fits.

Just to let you know that I solved the issue. I found a library where you can control the speed and make sure it get to it's position. You can find it here: https://github.com/netlabtoolkit/VarSpeedServo I incorporated it in the Mysensor sketch and it works eventhoug it looks like it only goes like 90 degrees but it's enough for me : #include <MySensor.h> #include <SPI.h> #include <VarSpeedServo.h> // #include <Servo.h> #define SERVO_DIGITAL_OUT_PIN 3 #define SERVO_MIN 0 // Fine tune your servos min. 0-180 #define SERVO_MAX 180 // Fine tune your servos max. 0-180 #define DETACH_DELAY 900 // Tune this to let your movement finish before detaching the servo #define CHILD_ID 10 // Id of the sensor child MySensor gw; MyMessage msg(CHILD_ID, V_DIMMER); VarSpeedServo myservo; // create servo object to control a servo // a maximum of eight servo objects can be created // Servo myservo; // create servo object to control a servo // a maximum of eight servo objects can be created Sensor gw(9,10); unsigned long timeOfLastChange = 0; bool attachedServo = false; void setup() { // Attach method for incoming messages gw.begin(incomingMessage); // Send the sketch version information to the gateway and Controller gw.sendSketchInfo("Servo", "1.0"); // Register all sensors to gw (they will be created as child devices) gw.present(CHILD_ID, S_COVER); // Request last servo state at startup gw.request(CHILD_ID, V_DIMMER); } void loop() { gw.process(); if (attachedServo && millis() - timeOfLastChange > DETACH_DELAY) { myservo.detach(); attachedServo = false; } } void incomingMessage(const MyMessage &message) { myservo.attach(SERVO_DIGITAL_OUT_PIN); attachedServo = true; if (message.type==V_DIMMER) { // This could be M_ACK_VARIABLE or M_SET_VARIABLE int val = message.getInt(); myservo.write(SERVO_MAX + (SERVO_MIN-SERVO_MAX)/100 * val,255,true); // sets the servo position 0-180 // Write some debug info Serial.print("Servo changed. new state: "); Serial.println(val); } else if (message.type==V_UP) { Serial.println("Servo UP command"); myservo.write(SERVO_MIN,255,true); gw.send(msg.set(100)); } else if (message.type==V_DOWN) { Serial.println("Servo DOWN command"); myservo.write(SERVO_MAX,255,true); gw.send(msg.set(0)); } else if (message.type==V_STOP) { Serial.println("Servo STOP command"); myservo.detach(); attachedServo = false; } timeOfLastChange = millis(); }
