    I cannot save data sent from Arduino Uno to Raspberry Pi.

    I am trying to send sensor reading from Arduino Uno to raspberry pi and I want to save this incoming sensor reading to SQLite which I downloaded to Raspberry pi. I used lm35 sensor on Arduino Uno and i used the i2c way for communication between Arduino Raspberry pi. I managed to transmit the...

    How to bypass BIOS password on an SPI EEPROM

    Hey, first of all I would like to say that basically all of what I'm talking about is far far away from my comfort zone and everything I know is from a 30 minute research on this topic. So I am trying to reset BIOS password on an old ASUS X51L laptop because everytime I turn it on I first have...

    i2c Pull-up resistors for multiple chips

    Hi there, I wish to connect multiple i2c chips together on the same PCB board, these chips are DS1307, DS1621 and AT24C256. My question is, do I need to put 6 x 4.7k pull-up resistor (2 resistor / chip) or 2 x would be Ok for those three chips as shared? Also what will happen if I would...

    Can I2C and PWM be in the same connector?

    Hello all, I have a daughter board that resides about 1m far from main board, this daughter board contains buzzer and some ICs. I am already worried that I2C won't work properly over this long distance and now that I added PWM, I am afraid that will disturb I2C and lose connection between the 2...

    Arduino i2c communication hangs while running motor

    I have a Arduino uno board connected with PCA9698(I/O expander) through i2c communication. Controlling if input and output were working correctly. The data pins from the PCA9698 is connected to the 24v DC motor driver(BTS7960) and also sensors(PROXIMITY sensors). While reading the sensors there...

    BNO085 - Bringup

    Hello, I tried to breakout the BNO085. I used a known good design from Adafruit (attached the schematic). Now unfortunately it doesn't work. I written software for the Adafruit board and it works fine. Then I replaced the Adafruit board with my breakout board ("schematic_not working" in the...

    Array of I2C buses

    Hi! I am new to FPGAs and I am working on a project that involves an array of I2C sensors. I need to record real-time data from all sensors at the exact same time. For now, I am just trying to plan and understand more about how I would do this with an FPGA. For an FPGA such as the LCMXO2...

    Communication failure using PCA9615 Differential I2C Bus Extender

    I have used PCA9615 differential I2C bus driver in one design to extend the I2C bus over CAT5 cable. (datasheet https://www.nxp.com/docs/en/data-sheet/PCA9615.pdf) The design has been done according to the datasheet recommendation and with the help of a reference design of a popular open-source...
