Hello everyone,
I'm trying to use the TQMa6x using the USB port but when I connect my card nothing happens, black screen and I can't see what the problem is.
Thank you in advance for your answers.
Hey all, I was wondering if someone could point me to a component that fits this description. Id like a USB that plugs directly into a computer with voltage terminals and converts it into a digital representation that has existing support in a programming language to easily read in the data. The...
Hello everyone,
Id like to request some help on how to implement USB onto a project. I am currently working on a project that sends analog signals to a computer using a headphone jack and plots it into a graph. Id like to do the same but using a USB port instead as it is standard and easier to...
Hi,
I'm pretty new to all of this, so please let me know if something doesn't make sense.
I am building display units with LEDs in them, powered by a 5v USB C to make it easy to disconnect and cable manage. I would like to put a USB C port on the left side of the unit, as well as another USB C...
Hey all,
I'm currently building an escape room & have decent good electronics knowledge, however, I'm on a project that has stumped me:
We have an arcade machine built with a custom mini game running on a pc, the controller joystick and buttons operate via a usb decoder & are fully...
Hello everyone, i am new here and i don't have any education about electronics. I have just learnt very basic things from internet and by breaking, modifying and damaging electronics..!! I have done assembling computers and repairing motorcycles.. i love fiddling with electronics..
Anyways...
Hi everyone, I'm building an USB charger with a linear PSU just for hobby and I want to install an USB 3.1 port so it can supply 900 mA max.
If I only connect up the USB 3.1 port VBUS and GND pins, will the device recognize it as USB 2.0?
I'd like to know what I should do with the other five...
Hello true tech enthusiasts,
I'm trying to do this:
Long story short my USB drive stopped working after it would randomly not be detected at times on my PC.
Found out it was bent and a pin in the middle was slanted. Now it wouldn't detect at all. So I'm trying to desolder the metal part...
Hello All,
I am using Raspberry Pi 4 which comes with 4 USB ports. For my project, I have two mics and both will be connected to Rsp via a USB port. I need to be able to choose which Mic needs to be ON. So basically I need to be able to switch/choose which USB port I want the sound to come in...
I wanted the MCU I'm using, samd21g, to detect when USB is connected on the board. The USB is used to power some other things on the board and currently isn't connected to the MCU. Also, the MCU can only handle 3.3V. I have a pin open on the MCU that I can connect the power of the USB to it...
Hello !
So I am starting scratch the surface of the Embedded systems world. I have always wondered how to interface a microcontroller like the AVR for example with a USB stick to read the file names for example or the space left or even format/delete files from the USB stick without using any...
Hi there,
I designed a PCB which has a FE1.1s USB bub controller. The problem is that when I connect my device to computer,"device not recognized" error appears. device LED's turns on for a moment and everything goes off again.
I have searched for driver issues but it seems that everything is...
Hello
I am trying to make USB connection to PIC18f14k50.
Following are connections :-
Pin 1 (Vdd)------>5V
Pin 2 & 3 -------->External crystal oscillator (20MHz)
Pin 4 (MCLR)------------->Pulled high with 10K
Pin 20 -------------------->GND
Pin 17---------------------> capacitor (0.1UF)...
I have a Focusrite Scarlett Solo interface. I can power it up normally from a laptop usb output. But i want to use it without a laptop or pc so I only need to power it up using an ordinary usb charger. It won't work with a usb charger only.
It seems it won't power up without the communication...
Without getting too into the weeds of my project; what I am attempting to do is to control the plugging in and removing of a basic USB device. To accomplish this, I have cut open the USB cable of my USB device and have cut the 5V line. I plan to connect the two sides of the 5V line to two...
Hi! After producing multiple different PCB designs of a board for controlling a stepper motor, I noticed something that I cannot explain.
The boards are in general powered through 12 volts, then a voltage regulator brings the voltage from 12 to 5 V and another one from 5 to 3.3 V. Stepper...
Hi!
I want to power an Arduino project with external, regulated 5V (say up to 1.5A). For versatility, I would like it to have a USB-C type input connector so I can grab any 5V charger I have laying around at the time of using it that can deliver at least 1.5A@5V.
I read that connecting 5.1k...
I've recently been design a PIC development board with USB and other peripherals, I've got the board working, got code running on the board and managed to test all of the peripherals that worked great, until it came to USB.
The issue isn't the USB circuity its self, I've recently brought a new...
USB was intended to be a universal data connection protocol and hardware standard, and has been passably successful in so becoming. However, the more I see of USB C the less I like it, especially solely as a power connection for SBCs such as Rpi. It's like using a steam-shovel to hammer a nail...
