Re: SmartRFy USB Module (HCMODU0144)

The only other problem antenna wise, I suppose the more signal may swamp the receiver. The receivers do have an AGC and the protocol (which is compatible with our Arduino HCWireless library btw) does send a preamble to give it time to adjust, but to what level it can handle I'm not sure. It would b...

Re: 8x8x8 cube programming

This should hopefully fix it....

HC8x8x8Cube.cpp


It's just the Line() and _Diff() functions that have been modified slightly if you just want to cut and paste them into your current file.

I'll hold off uploading this fix to the library thread for a while just in case..

Re: 8x8x8 cube programming

Thanks. I can see the problem and it should be a quick fix. I'll post an update tomorrow as soon as I get chance to check it works.

Re: SmartRFy USB Module (HCMODU0144)

Thanks for the feedback. We may at some point switch to a coiled wire instead of the spring antenna. This would give the option of being able to straighten it improve efficiency. I have actually done some tests on the modules with just a straight 1/4 wave piece of wire and as expected it does seem t...

Re: 8x8x8 cube programming

It's to stop the possibility of a divide by zero error when calculating the step sizes. Although, I can see that it is making a test in the line function pointless so i'll take a look at it as soon as I get chance. If you have an example of how the line function is not working correctly I can take a...

Re: HCPCA9685 - Library for PCA9685 16ch 12bit PWM controller

The library will work fine with the Mega but the I2C pins (SDA & SCL) are on different pins. You can connect it like this: PCA9685...........Mega GND.....................GND OE.........................N/A SCL......................21 SDA.....................20 VCC....................5V You don't need...

Re: 1.3" SH1106 uOLED Display Module (HCMODU0058 & HCMODU0059)

I'm guessing from your comments that you're using our HCuOLED library. If so you would connect it like this: OLED.............WEMOS D1 GND..............GND VCC..............3.3V D0/SCK.......D5 (GPIO14) D1/SDA.........D7 (GPIO13) RST.................D1 (GPIO5) DC..................D2 (GPIO4) CS.........

Re: 8x8x8 cube programming

Well an update to the design isn't going to happen for quite a while anyway. What with the current Covid situation we've had to concentrate on just getting orders shipped out and so our (very long) queue of projects has been put on the back burner a bit. The 4x4x4 cube kit is planned to be updated b...

Re: 8x8x8 Cube. Not lighting up.

The pcb populated and tested using LEDs in the positive and negative posts and they all light up. I assume this means when you connect a single LED to the PCB it is flickering on and off as it runs though its patterns? If so this is a good sign the PCB is working and it's likely the issue is with t...
