Re: 8 Channel Bi-directional TTL Level Shifter (HCMODU0113)

We've contacted the supplier but unfortunately there is no schematic available for this module. Taking a look at the module itself it appears to be a simple circuit where each of the 8 lines has couple of FETs which are used to pull down two 10K resistors. One 10K resistor is tied to the VCCA rail, ...

Re: 3.2" TFT Shield with resistive touch (HCARDU0109 & HCARDU0111)

Yes that's right, it is using the IL9327 controller. The confusion is our mistake - Open smart changed the controller it used in the 3.2" displays some time ago. We updated our HCDisplay library and as the display had a different controller listed the display under a new SKU (HCARDU0111). However it...

Re: 3.2" TFT Shield with resistive touch (HCARDU0109 & HCARDU0111)

I assume you uncommented the following line:

  1. #define HX8352B_SHIELD                      //3.2 Inch TFT shield (SKU: HCARDU0109)

If so can you uncomment the line for the HCARDU0111 (ILI9327 controller) instead and give that a try:

  1. #define ILI9327_SHIELD                          //3.2 Inch TFT shield (SKU: HCARDU0111)

Re: Elec Freaks Shield for Mega (HCARDU0098)

Good news! We've managed to source 3 of these shields. These are expected to be in stock either end of this week or early next week. Note that this item has now been discontinued so once these shield sell we won't be stocking them in future.

Re: Elec Freaks Shield for Mega (HCARDU0098)

Unfortunately we're having trouble obtaining new stock of both the screens and the adaptor shields. I've just done a through search of our stock in the off-chance there may be a rouge one hiding somewhere but with no luck. As a last ditch attempt we've contacted the supplier to see if they have any ...

Re: STM32F103 Black Pill Development Board (HCDVBD0033)

Thanks, although you only seem to have fixed the linked blog, not the ones up top of this thread. Possibly the BB software won't let you do that? Your browser is probably caching the old version. Try doing a browser refersh (ctrl-r in chrome) The diagram on the spec sheet marks a block of green "an...

Ah! I see the problem. You have the wrong version of the GUI. The one you have is for the EDTracker pro, you need the DIY version (EDTracker2-GUI-V4.0.4.zip):

Re: STM32F103 Black Pill Development Board (HCDVBD0033)

Thanks for pointing this out. I can confirm that this is a design change and affects the very latest batch of modules. I have now updated the images in the first post to reflect this change.

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

Win 10 recognice the device and i can try it under peripherals proprieties Do you mean that it is appearing as a game controller in Windows settings? , instead under EDtracker software there's no device, any hint? The most likely cause is that the drivers for the Pro Mico haven't installed correctl...
