TinyDuino Processors & TinyShields / Using TinyZero with MicroSD shield

« on: October 25, 2019, 12:06:43 PM »

I'm looking at their example program "listfiles" (attached for reference, it's a small program) and it doesn't work with the TinyZero and MicroSD adapter as written. I think I need to set the proper pin as in the text below from the program:

  SD card attached to SPI bus as follows:
 ** MOSI - pin 11
 ** MISO - pin 12
 ** CLK - pin 13
 ** CS - pin 4 (for MKRZero SD: SDCARD_SS_PIN)

I haven't yet found which pin to use. Or a different way to talk to the SD card?

Anyone have any further information on this? Or a working example? It would be very helpful and appreciated.

TinyDuino Processors & TinyShields / Re: USB shield and Proto Terminal Blocks don't fit together

Thanks for the reply. I understand this is an evolving product line and there will be issues as new ideas come along and have to be fit in with existing hardware. Part of my reason for posting and asking was to see if there were other ways (plug extensions, whatever) available to solve this one, and partly to show others a way to solve it. My way's working fine for now. I'll keep an eye out for the new board configurations.

I stumbled onto your stuff at Fry's and bought a starter kit. Then I ordered a small selection from Tiny-Circuits. I can already see some more I want to get.

TinyDuino Processors & TinyShields / USB shield and Proto Terminal Blocks don't fit together

« on: August 09, 2015, 09:55:36 AM »

I'm stacking a processor board, a USB board and the Terminal Block board for some Hall Effect sensor experimenting. When I do this stackup, a normal USB micro plug doesn't even come close to fitting into the available socket. I don't get what they were thinking. Or am I missing something? This seems like a very basic use of the products. Something they'd have designed for, and tested and/or lots of people would be running into this.

I cut away one side of the USB cable plug housing and ground down the excess pin and solder protrusions under terminal sockets 8, 9 and SS. Fortunately there was plastic material inside the USB plug right where it wants to contact those ground down pins so now everything works perfectly for me. Photo attached.

What are other people doing? And why did I have to do this?
