what does the digital oscilloscope say?

UUmesh Lokhande Yes, it'll work, and the list of components you have is good enough to get start...

Alright, thanks! Will order them now, i was waiting for someone to tell me for sure that they're okay

az sum misho•12/2/24, 6:01 AM

Will keep you updated

why is your clock wierd? it should be pulsing no

ZZacckOsiemo why is your clock wierd? it should be pulsing no

segfaultdev.elf•12/2/24, 6:24 AM

that's the issue

melta101•12/2/24, 6:24 AM

something seems to be pulling it low

Mmelta101 something seems to be pulling it low

ZacckOsiemoOP•12/2/24, 6:25 AM

Yes @undefined.elf fix the clock first look at your reference manual and see why it’s not pulsing perhaps look at apb and ahb registers

Mmelta101 something seems to be pulling it low

segfaultdev.elf•12/2/24, 6:25 AM

the thing is library should initialize the SPI peripheral

segfaultdev.elf•12/2/24, 6:26 AM

but that's not happening or something else overwriting my configuration

ZZacckOsiemo Yes @undefined.elf fix the clock first look at your reference manual and see why...

segfaultdev.elf•12/2/24, 6:26 AM

I am using esp32

ZacckOsiemoOP•12/2/24, 6:26 AM

Seems like it is using a different pin for clock read the library code see what pin is being used

segfaultdev.elf•12/2/24, 6:26 AM

if it was STM32 then I could rock

ZacckOsiemoOP•12/2/24, 6:26 AM

You can rock here too

ZacckOsiemoOP•12/2/24, 6:26 AM

Get the same document

segfaultdev.elf•12/2/24, 6:26 AM

there is a configuration file

ZacckOsiemoOP•12/2/24, 6:27 AM

segfaultdev.elf•12/2/24, 6:27 AM

I defined everything there

ZacckOsiemoOP•12/2/24, 6:27 AM

But at the moment you can t trust that because it’s not working

segfaultdev.elf•12/2/24, 6:27 AM

even though spi is not working

ZacckOsiemoOP•12/2/24, 6:27 AM

Is it a risc v or arm esp?

ZZacckOsiemo Is it a risc v or arm esp?

segfaultdev.elf•12/2/24, 6:28 AM

RISC V

segfaultdev.elf•12/2/24, 6:29 AM

the thing is I used adafruits library

segfaultdev.elf•12/2/24, 6:29 AM

and that worked fine

segfaultdev.elf•12/2/24, 6:29 AM

I configured the pin number in the same way

Aaz sum misho Will keep you updated

Umesh Lokhande•12/2/24, 6:39 AM

Sure, and meanwhile try to read blogs abt those sensors modules and watch YT videos. So by the time they arrive, you already have some know-how.

Ssegfaultdev.elf I configured the pin number in the same way

ZacckOsiemoOP•12/2/24, 6:44 AM

Ah then the new lib is broken, you have to read it

ZZacckOsiemo Ah then the new lib is broken, you have to read it

segfaultdev.elf•12/2/24, 6:45 AM

Only CS pin is working fine

segfaultdev.elf•12/2/24, 6:46 AM

maybe something overwriting my configuration trying to figure that out

Ssegfaultdev.elf maybe something overwriting my configuration trying to figure that out

ZacckOsiemoOP•12/2/24, 6:47 AM

Yes read the library code e

ZZacckOsiemo Yes read the library code e

segfaultdev.elf•12/2/24, 7:30 AM

trying

segfaultdev.elf•12/2/24, 7:30 AM

it's a huge library

segfaultdev.elf•12/2/24, 7:30 AM

and generic also

segfaultdev.elf•12/2/24, 7:30 AM

what a pain

Ssegfaultdev.elf trying

ZacckOsiemoOP•12/2/24, 7:33 AM

You see now, this is why you don’t use or build a Hal it’s easier to just write straight code for the functionality you need

ZacckOsiemoOP•12/2/24, 7:34 AM

Because we maintain code more times than we write it, we need to optimize for that rather than for well written code

ZZacckOsiemo You see now, this is why you don’t use or build a Hal it’s easier to just write ...

display driver with widget library

segfaultdev.elf•12/2/24, 7:42 AM

segfaultdev.elf•12/2/24, 7:42 AM

got this tiny display 1.14 inch

segfaultdev.elf•12/2/24, 7:42 AM

resolution is pretty good

segfaultdev.elf•12/2/24, 7:43 AM

so I was planning to draw some widget on it

segfaultdev.elf•12/2/24, 7:43 AM

and hell

Ssegfaultdev.elf so I was planning to draw some widget on it

ZacckOsiemoOP•12/2/24, 7:43 AM

Challenge, plot imu values on that in a graph form

ZacckOsiemoOP•12/2/24, 7:43 AM

Is that on esp?

ZZacckOsiemo Is that on esp?

segfaultdev.elf•12/2/24, 7:43 AM

yes

Ssegfaultdev.elf yes

ZacckOsiemoOP•12/2/24, 7:44 AM

Can you have it talk to the st?

ZZacckOsiemo Can you have it talk to the st?

segfaultdev.elf•12/2/24, 7:44 AM

If I want then

Ssegfaultdev.elf If I want then😑

ZacckOsiemoOP•12/2/24, 7:44 AM

Yes plot signals from the imu on the st on this display

ZacckOsiemoOP•12/2/24, 7:44 AM

Now. Go

ZZacckOsiemo Yes plot signals from the imu on the st on this display
