Re: LED Selection not working as doccumented

The first time I ran the IDE it immediately offered to update the firmware, so I presume it is fully updated now. How do I know which firmware the board currently has? I don't see anything relevant in the "intro" string when I open up a screen terminal to the MicroPython interpreter. It shows the Mi...

Re: LED Selection not working as doccumented

I just received an M7 from Banggood and I'm having exactly the same problem. I think I have precisely the same product as the OP. I can see the IR leds illuminate, and red and green work (although they are tied to the wrong numbers in the code), and blue doesn't work at all. BTW, mine has similar wr...

Re: Second SPI device while using LCD shield?

Yeah, I get that. No disrespect. I'm coming in pretty new here. I've been tinkering with PyBoard since the spring (late to that party too, I admit), but I'm not even foot in the door with OpenMV. I don't have it in my possession yet. :-)

Keep up the good work.

Re: Second SPI device while using LCD shield?

Cool. My M7 and LCD are still in the mail. I'm brand new to OpenMV. I had misunderstood the whole thing to be a "camera module" to some otherwise external central controller (a PyBoard), but I'm discovering that that line of reasoning doesn't quite follow. For one thing, the M7 and H7 are actually m...

Re: Second SPI device while using LCD shield?

Thanks for the input. Aside from driving a second SPI device, I would also be amenable to joining an M7 or H7 to a PyBoard and letting the PyBoard talk to further peripherals with its own SPI buses -- but of course I would still have to connect the camera and the PyBoard. That could be done over UAR...

LCD shield P8 "SPI commands"?

How is the use of P8 different from P0 with the LCD shield? It is documented as "SPI commands". What sort of commands are issued via P8 as opposed to simply being sent as SPI data over P0 (MOSI)?

Thanks.

Second SPI device while using LCD shield?

I presume the LCD shield is driven from the SPI bus, correct? The docs for the lcd MicroPython module don't specifically describe the comms (the string "SPI" doesn't even appear on that doc page), but it does say it utilizes pins P0, P2, P3, P6, P7, and P8, which looks very much like SPI access. As ...
