...:: 1x [OSRAM ams SFH 4715AS A01] These LEDs must be mounted to a PCB of specific dimensions at a specific location. (See the attached file). Note that space is quite constrained - the PCB with the LED mounts is quite small so it may be required to break the system into two boards connected via a flex cable or similar The LEDs must be able to be driven from a Raspberry Pi 4, with input from the GPIO pins. At a certain time only of the two sources (i.e. IR or white) will be active. The brightness of the LEDs should be controllable via PWM. Your task is to design a PCB with the above requirements with... 1. Analyze the power consumption of the system -- these are high power LED and an RPi has limited current supply to peripherals - your design must take this into consideration...

I need a basic small app that MUST run on Android 8.1 platform. No major work on interface required. The app will Subscribe to a user defined MQTT broker/message/payload that once recieving the message/payload turns on or off one of 2 GPIO relays located on the Android platform the App is running on. The app must be capable of running in the background with low overhead and the app must be loaded on platform startup and placed in the background. The API for the GPIO's is attached in the image attached I would like for this to be open source for the Home Assistant Community to tinker with as needed.

Hi Evan. I have a project that is 8051 based. Command set is well defined, but we need to overlay a bit-banged I2C command set using GPIO pins. If you accept the project, we will make a good budget for you. The project is an urgent one. Let me know your thoughts. I'm from Detroit.

Hi Ciro L., If you accept this project, we'd create a good budget for you. We have an assembly language assignment that is based on the 8051 microcontroller. We need to essentially recreate an I2C command set and 'bit-bang' I2C on some GPIO pins. Do you think you can do such a thing for us?

I require a sketch for an ESP 8266 (ESP 01) as follows: - ESP 01 has 2 GPIO so the setup should work, if not a node CMU can be used - read out/count impulse of reed contact (gas meter counter) o 8266 - read out voltage meter o - display on simple website as follows (access via IP if ESP is online) o text: gas counter o gas counter today: xxx value (each count is 0,001 m3 ) o voltage: xxx Volt o Date - send data to influx DB o gas counts or gas usage in m3 o voltage

We are moving from succesfully configuring Raspberry Pi's for our livestream players to using Beaglebone's instead (due to the Raspberry Pi chip shortage). We have configured a Beaglebone, but need an experienced Freelancer's help in getting and setting up a suitable player for an incoming rtmp live feed.

We have interfaced sensors and actuators to NI-DAQ. We need support for developing LabView application for controlling the system. The application will communicate with the NI-DAQ and control the GPIO. LabVIEW experience is required. The flow and GUI will be shared in chat

Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

I have a project that will require combining elements from separate breakout boards into one PCB that can connect to a raspberry pi over GPIO. Elements to incorporate into the design include: - Power circuit with load sharing and hot-swapping - IT8951E-64 controller (SPI) - NFC reader - Accelerometer - Touch screen controller I would need you to create the circuit schematic, PCB design, BoM etc. As this will form the first fully functional prototype of what will be a commercial product, I would need you to sign an NDA before I share more specifics (I have more detail on the components to integrate and a video of the exiting prototype to share). Thanks, Graham

Assistance needed in porting code written for a PIC18F26K to a more modern model (that is in stock). Program is about 400 lines of C, I suspect the model number may need to be changed and a few pins remapped, but otherwise the code is usable. Currently using 1 A/D, TX/RX for serial and 4 GPIO pins. The code is doing battery management. If it is less time the code could be ported to Atmel or Arduino if decided, it is not doing a whole lot. Bonus points if you are familiar with Raspberry Pi. This project sends data via serial to the Pi and that also needs some updates. Can discuss that further after this is completed.

I need a program on a raspberry pi that will do the following (in these steps) 1. Read the GPIO inputs on the PI (all of the GPIO as inputs), and will display the GPIO number in the console 2. Once step 1 is complete, then the next step is to read a 4 digit number and display it on a 4 digit number readout through the serial port 3. Once step 2 is complete, then we will link the 4 digit number to a MP3 file on a USB or Network attached hard drive directory and play the media through the audio output. 4. Once step 3 is complete, then we need to be able to make a queue of files. Meaning if you enter a 4 digit number, then it will play the file. If you enter another 4 digit number, then it will put that next file in queue. You can put as many files in the queue as yo...

I am looking for an embedded system can detect objects in identified area by camera and send active low signal on GPIO pin.

We need auto-select transformer windings based on the detected input voltage. The possible voltages are 100,110,120,200,208,220,240. It is envisioned that an Arduino (which could be embedded into the circuit) of whatever flavor is used to select the voltage based on the sensed voltage. The circuit should be able to hand...Triacs will need to be turned on and off based on the voltage sensed. As an example, if the detected voltage is 240 and given that white will always be connected to the ground, orange goes to the hot side and black is bridged to brown. so the Triacs need to be turned on as appropriate to match the detected voltage. We can create the sketch in-house if required to cause this to happen. We need the GPIO pins on the arduino to do whatever they need to safely turn on t...

Hi I'm looking for someone who has Raspberi pi (preferably number but doesn't matter, you'll help me adapt it later) at home and is connected to his network. Someone to implement: 1. take a voltage data from a specific GPIO (you can let me know what exactly you chose) 2. transmit the data (voltage) continously via LSL. 3. Check it with Labrecorder (on a different PC) Preferable people with two raspberi pi so they can check the LSL they wrote is working well in time. (should not be a difference in the time domain if both devices get the same voltage spikes at the same time - same data to both, but possible to make readings with different freq.) The freq. should be higher or equal to 512Hz.

The second phase firmware would allow the option of converting from 3 evenly space interleaved square waves 120 degrees apart to 4 interleaved square waves 90 degrees by reading the digital input on one of the GPIO pins. This pin will be read at start up and the board will always operate in that one configuration, this will not be required to change phase mode once powered up and operating. A low signal on the pin would designate 3 phases and a high signal could designate 4 phase o...

I need someone with ACTUAL experience programming the Raspberry Pi Pico/RP2040 to implement a variety of small projects using the RP2040 as part of a larger project. As an introduction, I'd like you to create a program that transfers a program resident in the RAM of one PICO and transfers it via a pair of GPIO lines into the SWD port of a second PICO and then boots it. If you have a third PICO, it would then transfer the program to the third PICO and boot that and so on. The actual program for now can be a simple flashing the LED 'hello world' program. The key thing is that it must NOT move the program into Flash, only into RAM. I already have a solution to this so am just using it to compare your skills against what I need going forward.
