Microcontroller Jobs

I need to implement digital signature algorithm in Xilinx Vivado Design Suite using Verilog. Please find the attachment for complete details of project.

Code need to work on Arduino IDE with espressif/arduino-esp32 1.0.6 I need to detect a very fast pulse end moment (10-15ms lenght) but since ESP32 takes +200ms to start up, it's must be done from wake stubs 1. Esp32 it's in deep sleep or hibernation mode 2. HIGH pulse interrupt and wake up 3. Wake stub looking for LOW/Falling 4. Wake stub detect LOW/Falling , take the time into variable and wake up as normal 5. Normal operation, print how many microseconds elapesed from LOW time Note: Your stub code must be boot up in less 10ms, otherwise it will not be able to capture the moment from HIGH to LOW Use what ever gpio number for interrupt (DEVKIT-C) Image included for better understanding

Hello there! I need someone to help me with a Nextion+Arduino project that I am working on. What I want you to do is to check the files that I have already made using Nextion Editor and Arduino to talk to each other. I'd like you to check them, improve them in terms of looks, operation and help me with what's undone. Basic idea is we have a display and Arduino and we want them to talk to each other all time and make the changes on Arduino side, I also have an I2C based battery fuel gauge IC so I'd like you to help me to track it's SOC as well. If you are someone who has worked with Nextion Displays and can do this, kindly bid. I'd prefer it if you have the display at your end and can test the firmware on Arduino and test the HMI interface on the display parallel...

Running digits in 7-segment display: The purpose of this code is to display and scroll the number that is being typed with the matrix keyboard. Each time a number is pressed, it should appear in the 1st display on the right, and the number that was in this 1st display will now be placed in the 2nd display and the number that was in the 2nd display will be placed in the 3rd display, so that the number that was in the 3rd display is lost. This code must include the enter function, which is when it receives a number greater than 9 and at that moment it will proceed to deliver the number that forms the angle but converted into binary, with the restriction that the number is not greater than 180. In case it has received a number greater than 180, it must deliver x "B4" and place 180 i...

Microcontroller is considered as the backbone of Embedded System& it's most important feature is: "It can think". A Microcontroller looks like a simple electronics chip, but in actual its too powerful (also called Embedded Computer) because its programmable. Using programming code, we can control all I/O pins of a micontroller and can perform multiple functions. Before microcontrollers, DLD gates were used to create logics i.e. adding delays, turning signals ON/OFF etc. DLD is still in practice for small projects but if you are working on big industrial projects, then DLD circuits become too messy & thus too difficult to handle. In below figure, I have added two circuits of traffic signal lights: Left Circuit: 555 Timer is used for creating the LED sequences. Right C...

I need the design for converter / dimmer that can be used with a typical DALI LED drivers. It needs to provide the following functions: 1. Conversion of 0-10v dimming signal to DALI dimming commands to go to the DALI LED driver 2. Dimming of the LED light through the DALI LED driver using a rotary switch (or potentiometer) to provide 90,80,70 ... 10% dim levels. 3. Bypassing of the unit and changing it to a simple conductor using a switch. It can be part of the switch used for dimming. You'll provide the schematic design, firmware for the microcontroller, parts list. You'll need to provide verifiable relevant work history and references to be considered. Thanks

Hi, We already have a working recorder which saves wav files to an SD card (CPU already reduced to 80Mhz). Worked great but we need to lower the power consumption (Now: 30mA). I wish to get less than 5mA. Hardware: Digital mic (I2S or PDM) and SD card connected to a ESP32 I am pretty sure it is possible to record wav files in light sleep mode. Here is what i have in mind using I2S in the example. But not 100% sure if that works: - In light sleep mode the I2S interface writes data from the I2S microphone to a buffer (I hope that DMA or any other memory is accessible) - A timer wakes up the main CPU when the buffer is full which writes the data to the SD card - I2S and the main CPU can't have access to the same buffer at the same time. So once the timer triggered. I2S starts writing...
