Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

I've attached a new version of the library. Hopefully this should fix the issue. Can you give it a try and let me know if it works. BTW, is there any way of dimming the displays (I'm thinking to dim them if no activity after a certain time, not power off just 1/2 brightness or something from a contr...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

Just to be clear you're saying the displays do work after the reset, it's just that you're seeing some weirdness happen whilst the reset? Also, I forgot to mention, for whatever reason they (2 and 3) are briefly backwards (mirror) then the flip forward then clear Yes, both these things are done as p...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

The problem is that the reset function doesn't just toggle the reset pin, it also re-initialises the display. So when you reset all three displays with the reset function, although all three displays are actually getting reset, only the display your executing the reset function for is getting initia...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

I've just noticed that the text in the default patterns library are displaying upside down? Presumably all the patterns are upside down, it's just noticeable with text. Is it possible that you have the layers of your cube connected in the reverse order? Take a look at connectors L1 to L8 which run ...

Re: Hobby Components USB 8CH 24MHz Logic Analyser (HCTEST0006)

It should be based on the same firmware and fully compatible with SW suite sigrok and USBEE. Our analyser is programmed with our own firmware and will have different VID & PIDs so I doubt any information or drivers from this thread would work with your analyser. As this is the product thread for ou...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

The brightness of (or rather current though) the LEDs is controlled by the four 1K resistors R8, R9, R10, & R11. Increasing the values of these resistors will reduce the brightness. For example, changing them to 2K will half the brightness.

Re: EDTracker Bundle (HCKITS0021, 21B, 21E, 21F, 21G, 21H & 21I)

Thanks, and sorry to hear this.... However the power led on the MPU 9250 will not light when plugged into a USB port. Power led is lit on the pro micro, but no power light for the MPU. Duff MPU? The 9250 version doesn't actually have a power LED, it's just the GY-512 version that has the LED so I wo...

Re: HC4x4x4Cube Arduino library for 4x4x4 LED cubes

Very nice, I like how you can also use the jig to bend the legs in the correct place. The I'll get the link for the jig added to the first post of the product thread.

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

@bluethunder22 I think the comments I made in repose to Ramshackle's last post are also relevant to your issue. Adding the 100nF capacitors won't hurt anything but I think it's likely that although it's making the cube work, it's probably just making the actual issue rather than fixing it. If you wa...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Just to confirm (and summerise) by no change in behavior I assume this still means the following... 1) There is no activity from any of the cube LEDs. 2) The 4x 10mm base LED's do not flash then illuminate after about 15 seconds have past from applying power. 3) When touching certain pads you can ma...
