The result should be integration code for Nabto and ThreadX. We propose it done on an NXP MIMXRT1060-EVK (but other targets could also be discussed). Environment/Tools should be GCC and CMake. More on Nabto integration and the hence the tasks of the project can be found here: Integrations for FreeRTOS and Zephyr (and high-end operating systems) has already been done, so it should be a manageable task. We need to see documented ThreadX / Azure RTOS skills and knowledge, since we only have limited knowledge of this and our technical team is very busy.

A STM32F4 eval / discovery ( such as STM32F429I-DISC1, but also similar develop board) generates a PWM to controls a H bridge to driver a DC motor. The motor includes also two hall sensors: the MCU reads pulses and drives the motor CW/CCW, following a trapeizodal speed profile (modulating the PWM duty cicle). Appling a CAN (in the following: CAN-OPEN) interface we use an external tool (such as a very simple PC interface) to communicate to the MCU how many pulses is the race of the motor. The setting up of the number of pulses, ramp slopes etc can be done via a simple PC interface (ieg Pyton or something very simple) that send via serial/USB or CAN port those parameter. This is a pilot project. The final job will be more complex and complete: this project will be updated with a CA...

Project as discussed

Task 1 - I have stm32 project very basic just as a PoC with very basic I2C read and button. I need help with that project. Task 2 - Implement the above project professionally using DMA and FreeRTOS.

...RTC current time/date together with 2 touch buttons: (a) to access a dummy sensor value Graph (screen 2), (b) to access the RTC adjustment (screen 3). Switching between screens is done through touch screen button. Freelancer should send full source code (STM32CubeIDE project and TouchGFX) and should include a compile time External flash loader for use with STMcubeIDE or STM32Cubeprogrammer. FreeRTOS should be used with at least 2 threads: (1)GUI interface/Touch screen, and (2) all other functions. Note that I2C1 will eventually be used in both threads and sensor values will be passed between threads so a mutex and semaphores should be in place to prevent clashes and a high quality error/fault detection/ reset should be included for i2C1. Primary external oscillator will be 25M...

I want someone to help me build a real-time embedded system using MCUXpresso and FRDM-K64F. The project makes use of FreeRTOS. Please help me build this system. The description is mentioned in the file.

Looking for an experienced firmware, embedded programmer. You must be familiar with RTOS (esp. FreeRTOS) and the ST tool chain. Have experienced with development of industrial, rugged enterprise systems (not personal projects). Most of our projects involve bus communication including Ethernet IP. You should have your own hardware setup for development and bring-ups. This is a full time position. Please do not apply if you already have a full-time job. We need to be able to communicate freely over videos. You need to be fluent in English. Please submit some sample embedded code snippets or git repo for consideration.

Please do not respond unless you have actual knowledge of LWIP and the Netconn API. The background is here (not-looking-for-free-can-pay)/ See attached zipfile. The relevant function is EditGetData() which needs to stream in the data and write it to a file, via filebuf[512]. The file writing I can do. I just can't work out how to stream receive data using the netconn API. Examples on the web do not work.

Most likely it would involve sending out a running board, which would then make it easy (it is very self contained) and just needs a PC running Cube v1.10, USB connected, and an ethernet cable. But initially it could be just remote consultancy, by the hour. If you recognise the issues here (not-free-advice)/msg4297366/#msg4297366 then you may have the required skills.

I have written code to do all of these functions simultaneously, but only partially using freeRTOS. This project is to convert code to run reliably using freeRTOS. Freelancer must be expert in freeRTOS. This is a freeRTOS project. Freelancer must also have the following components: two ESP32, one I2S audio module, two SD card modules, one parallel Cap Touch TFT Display (320 x 240). Do not respond if you do not have these components and are not experienced in freeRTOS. In chat I will ask questions to assess your knowledge and ask for photographs of each of these components.

ESP32 Receive JPG over Uart, display on parallel TFT using freertos. Write to TFT Display to also be task in freertos.

I have the code ready but Task2 runs only first 2-3 times and then its not running, while Task1 running perfectly fine.

Looking for a long term firmware/embedded engineer. Familiar with low level embedded code on microcontroller in embedded C. Most of the work will be microproject task for long term. Code needs to be compiled and can be tested on any platform. Familiar with FreeRTOS, Embedded compilers like KEIL/IAR, STMicrocontrollers will have added advantages.

This project requires a developer with strong knowledge of ESP32 and LWIP. This project entails creating a new project, that can receive 128 UDP packets that are received at the exact same microsecond. Currently, with the default settings, the ESP32 receive buffers get full around 32 UDP packets, and then packets start to drop. We need much higher throughput. The ideal candidate is an ESP32 expert, with a strong knowledge of the lower level LWIP system. They must be able to demonstrate the configuration settings to increase the number of receive buffers, and increase the throughput on the ESP32.

NOTE: tight deadline Goal is to develop a prototype application for STM32 that can run LUA 5.4.4 scripts. Mandatory conditions are: - targets STM32L552 (nucleo board existing for that MCU, link to active stock given down below), however one can check on an other MCU as long as project is delivered to correct target. - STM32CubeIDE based project, latest L5 SDK - must run in an freertos task - must run some simple commands and call a custom C function. Custom C function will just blink a led. - no elua or simpler project. This must be the official LUA source code running. This is not meant to be a real application, just a working proof of concept. To be valid, the program must be run successfully on a nucleo L552 board i have. Compilable project will have to be given fo...

We use the FreeRTOS operating system in the Unattended POS device we developed. We use TI MCU, Smart Card Reader and Contactless card reader. We read VISA, MasterCard, Amex and Discover cards according to EMV standards. Some of these cards cannot read card data, data types are overloaded. We are looking for an Embedded System Developer to analyze them and fix bugs. Preferably, EMV Kernel and EMV card reading processes should be developed. We are planning long-term work. We will not consider those who do not write "61" at the beginning of your application.

I am creating a project which is based on the creation of a small HMI (Human Machine Interface) with a GUI programmed in Qt (Qt is a C/C++ framework and it allows the creation of interfaces also for MCUs). I would need the design of a schematic and the PCB design of an MCU board that has an STM32 series MCU, which either supports Qt on FreeRTOS or bare-metal. So, at the start, I would need to communicate with you in order to select the best option for the MCU, and then discuss other details. The MCU must be supporting at least 1024x600 resolution on TFT LCD. I would need a PCB that has: - MCU STM32 F7x series or other series (please advise me on this) - MIPI DSI 4L connector (for the LCD, which I already have the schematics) - touchscreen connector (that starts from the LCD and ne...
