    I have an Ambient Light Sensor (ALS), a Broadcom APDS-9250 connected to a FiPy development board containing an ESP32. The ALS to FiPY connection is via I2C. The programming language is MicroPython, the environment is Visual Studio Code and the FiPy is connected to the PC using a USB to serial converter. The test hardware is already built for the code and I have attached a drawing of the wiring. There is a dedicated PC connected to the hardware for you to use remotely to program and test this code. The code I require will interface the ALS to the FiPy. The purpose of the code is to measure the intensity of red light, specifically a flashing red LED. A flashing LED has been set up ready to test. This is test code. This code is to allow fine tuning of the ALS as a proof-of-con...

    Dear developer, I have an STM32G030F6 uC (TSOP20) with an external signal connected to PA10 (TIM1). I would like to read the frequency (0 to 10kHz) of that signal (rising flank) and store it internally (let's say every 200ms) and generate an internal interrupt so the software on that uC can make it available via I2C. TASK: deliver running and documented code for an STM32G030 that can count the rising flanks of the signal applied to PA10 to deliver the signal frequency (in Hz) as a stored value every 200ms. The rest of the software has to be made aware when a new value is stored (i.e. via interrupt or signal flag). please "TASK UNDERSTOOD" in your reply, so I know that you really read the task and you are no bid bot. Please also state your FINAL bid for this project...

    I am attempting to count flashes of a single red LED at a distance of approximately 30-60 cm. To accomplish this I have a fypi device - which is an integrated esp32 running micro-py connected via an I2C bus to a Broadcom APDS-9250. My requirement is code developed to communicate with a Broadcom APDS-9250, I have the fypi + Broadcom APDS-9250 hardware setup already. The code needs to flexible enough to allow me to change all of the Broadcom APDS-9250 parameters, using programmable variables - I have some limited programming knowledge. I would like the developed code to put the MCU into a deep sleep, using the low powered coprocessor to count the number of asserted interrupts in each 15 minute interval.

    Prefer .NET 5 and REACT framework for GUI, or Python Port over existing C++ code: I have a set of C codes: GUI running on a PC, and an embedded messaging controller running on a PIC32MZ processor. They talk over the USB. The PIC32MZ talks to a slave processor over a daisy chaind SPI. I need the GUI and messaging code ported to RPI. The 2 sub-systems can talk with internal messaging instead of USB. GUI is preferred to be based on .NET5 + React. RPI should operate headless via Remote Desktop. I need the code with source and step-by-step instruction to build up the image with Linux commands.

    Hello, There is a windows EXE file that I need help to decompile. Then I need you to find the area of the code that is responsible for the following: 1) How is tip data CRC calculated? The device has detachable tips. Each tip has a microchip in it. I can easily read the data on the tip using I2C protocol. But the data on each tip has a CRC. When I reprogram the tip data to something else, the machine rejects it because the CRC does not match. I would like to learn how to write the correct CRC to the tip when I change the data on the tip. 2) How to unlock the device. Sometimes the device locks and requires a code from the manufacturer to unlock it. The code is different each time. I would like to learn how to generate the code to unlock the machine. 3) I would like to know if...

    ...production ready PCB design. Key specifications are: 1. STM32 is connected to the FPGA: it receives the JPEG frames over SPI and controls the camera via I2C. FPGA triggers GPIO when new frame is completed. STM32 can do modifications on the camera settings and video stream. Additional tasks of the FPGA are the init-reinit of internal buffers, modules and stop video stream receiving cycle when MCU sends stop signal (using GPIO). In summary, FPGA must handle the situation when no input from the camera and the image parameters (e.g. resolution) are changed. 2. Configurable JPEG encoding: MCU can modify the encoder parameters via SPI or I2C. (Frame drop is possible because of high fps or limited out bandwidth.) 3.

    We use in our application 99 slaves connected to the I2C bus via the same adress 22. During sending data sometimes one slave holds the SCL line to LOW, which then blocks the whole system. Our idea is to have an interrupt routine, running as another parallel task, which detects SCL going LOW and if the line does not go HIGH again within a certain time (e.g. 500ms) the slave shall raise a flag to reset the I2C and give it free then it shall reconnect the I2C for further I2C data.

I made an example program just to figure out what libs I can get working and setup the pin assignments, I2C addresses, etc but that's about the extent of what I can do with the software.
