Finds the number of QR codes on a label and returns the value with appropriate GPIO action

ESP32 high rate parallel data out/input Proof of ability to connect fast BUS to ESP32. The goal right now is a 4-bit connection at a rate of 16.368 MS/sec, but the test is generic. In the test we will connect a BUS between two ESP32's with a clock where one will be used as a transmitter and the other as a receiver .The data can be entered into the transmitter in any form (.WIFI, Ethernet, USB etc. ) and prove their correctness in the receiver by comparison, or CRC or another idea

Hi Jian, Working on a design to automate: 2 off 5.5Nm motors with breaks and hall sensors to synchronise 2 off smaller motors synchronised. 1 off motor Running on python through a jestson nano 4 off cameras for obstacle detection, “esp32 cam”, data transfer over wifi, power is hardwired 3 wifi lights, power is hardwired. An LCD screen for up/down, a keypad/lock and error read out. I have someone who is a python guru. Could you help me with the hardware Thanks, Dan

• I need to monitor...in the same room. • There is a WIFI connected to the UPS and with a 4G chip. • The internet does not fail even in case of power failure. • Locally, there is a small server also connected to the wifi and the UPS that sends SNMP events to two external servers, ZABBIX and PRTG. • I need to monitor the drop and return of energy in these 5 energy points and know the ambient temperature. In short, on ESP32 or ARDUINO: 1) Make the list of material to be purchased; 2) Make a program that generates events via SNMP to a local server (cable or wifi) with a specific IP; 3) I assemble the hardware and make it available online so we can test your software; Please estimate the total cost of your work and the time to complete it, and get back to me as...

Read the full description of the project first, don’t bid if you don’t have experience, questions are welcome if related to the project. The project intention is to have 2 esp32, one of them will connect to a wifi Network and will be communicating with the second esp32 via serial, the second esp32 will connect to another wifi. When the second esp32 receives a request of an image via URL it will connect to the serial uart, and download the image of another url in the first wifi network and present it in the second esp32. A diagram of connections is: Wifi(A)<->Esp32(A)<——uart——>esp32(B)<->wifi(B) Only the esp32(b) can request images from A

I need to develop pressure sensor based coding for ESP32 mcu. Here, I am planning to use US9111 pressure sensor with mcp3421 ADC converter. I want to measure +5PSI to -5PSI pressure value, with auto zero calibration. When there will no pressure on the pressure sensor that must be zero value at the initial condition. It should be strictly maintain. It can be set by auto zero calibration. I want to measure pressure precisely, so you need to do the coding with exact calculation.

...may not slow down (?) but can process a certain input with 100% certainty. Comparing Cyclictest results between RTLinux kernel and regular os kernel is enough. Compile and configure the kernel source code yourself and change the local "uname" to show your name when you do "uname -a". EXTERNAL INTERRUPT Use of external interface: use one or two wires to event an RPI via GPIO pins. This can be done on the same RPI, for example from GPIOxx to GPIOyy or from an Arduino to RPI pin. Which reaction speed is feasible and why? This is similar to cyclictest but with external events. Thread: KERNEL CONFIG CODE The Linux kernel is open source. The RealTime Patch for Linux as well. The kernel configuration is very extensive - a lot can be set or turned

Hi there. Currently we are using a CPU Board of Actions S500 SoC with an AMOLED 1.78" MIPI-DSI I2C Touchscreen. It's working fine in our Board. Now we upgraded our PCB with RockChip RK3566 SoC. So I need some expert support to move the Touchscreen Driver from our old S500 PCB to the new RK3566 PCB. Also need some basic GPIO configuration. All necessary remote access support will be provided upon development. Please apply with a relevant portfolio. Required previous Rockchip ARM CPU with MIPI driver development experience. Developers from Shenzhen, China or HK are highly preferred. Thanks.

...connect to a central hub - which is another ESP8285 module. This central hub will be connected to a cloud server through a broadband router. It will send the data of all the 25 sensors to the cloud server. The cloud server will also reply back some data which needs to be transmitted back to the 25 sensor modules. Based on this data, the individual 25 sensors will perform some action, like setting a GPIO high or low. Tasks to be done: 1. All the 25 nodes should be starting their own Access Points, with SSIDs like "BSSUBMRL1", "BSSUBMRL2", "BSSUBMRL3".... passwords should be same as SSID. AP ahould be started in hidden form, so as not to crowd AP list in user domain. 2. The central hub should do following things every 30 min interval: a. Run a l...

Hi Everyone, I’m looking for an experienced ESP32 SW engineer to create a wireless file transfer tool. I have an ESP32 connected to a Teensy 4.1 trough SPI and Serial port bus and I need to transfer some files stored on the Teensy SDcard over Wi-Fi. Each file is around 100MB so SPI bus is the only option and a fast transfer protocol is needed. The code to be written is divided in two sections. 1. Code loaded on the ESP32 to include a small webserver where the user can open a browser and look at the files available on the SDcard and select the one to download. The ESP32 will request to the Teensy to transfer the files (ESP is the SPI Master) 2. Code loaded in the Teensy 4.1 will negotiate with the ESP32 the access to the SDcard. The Teensy will a...

I have created example images inside a template these will be category icon images on my website. I have utilized stock imagery from the Internet to create the current images. I would like you to create an original version of every one of the icons that you see at these 2 pages. The goal is for you to hand to draw a similar version. I will provide you with the template file for the outer border The yellow brand colour is hash code FEE200 We use a standard FFFFFF for the white elements And a standard 333333 for the black I'm hoping that you will hand draw these and then set them inside of the template border and create a Google Drive with all of the images saved as Photoshop as well as PNG optimized

You must live in the Western Balkans, Eastern Europe, Latin America, or the Caucasus. I am seeking a 15 to 20 year old who will help me build an Internet of things (IoT) device using MicroPython on the ESP32. ESP32 is similar to Arduino. You do not need to have any experience to work with me on this project because I would rather work with a person who is inexperienced but intelligent, rather than a person who is experienced, but not very intelligent. You will need to prove to me that you are a very intelligent person. Normally, you must work five days each week for one hour each day. You would be able to choose the five days that are convenient for you. You may work at any hour of the day (or night) that you prefer.
