    Problems in the communication between the Adafruit Feather (nRF52 Bluefruit LE - nRF52832) and the ESP8266-01

    Hi, My team and I were trying to connect an Adafruit Feather (nRF52 Bluefruit LE - nRF52832) to an ESP8266-01 through serial connection. The process is the following: 1. A bunch of sensors send data to the Adafruit Feather. 2. The Feather sends all the data via serial communication to the...

    How to interface CMOS image sensors with 32-bit Microcontrollers?

    I've been learning to program 32-bit ARM cortex-M controllers with an STM32 Nucleo (L476rg Nucleo). I've been playing with interfacing and controlling stepper motors so far. My next step is to move on to machine/computer vision and incorporate image sensing however upon some searching (hopefully...

    why in this article baud rate is considered as bit period or bit rate?

    I have read this article where I want to save a small question that made questionned my understanding: 1-first question: in this article baude rate/bit period, how can he takes the bit period as the baud rate. in my understanding, bit rate=(1/bit period) = baude rate* number of bits in 1 baud...

    Connecting two ethernet MACs without PHYs

    Hi, I am designing a board that utilizes an NXP LS1046a processor and multiple Kintex Ultrascale FPGAs. The plan is to connect the processors up to the three FPGAs via the 1Gbe links. Since they are all on the same board, the plan was to try and connect them up without using any PHY devices...

    RS485 communication issue

    I have Setup like this for my application. I have Transformer which gives out 12V 1A & 5V 500mA output.I have used isolated ADM2483 design where power galvanized isolated. Primary side 5v &gnd taken from 7805 regulator where 12v input comes from transformer. same ground used by MCU/ADM2483 side...

    RS485 Communication issue,

    Dear all I have used PIC18F45k40 device for RS485 communication. I have 2 ckts one is isolated and another non isolated RS485 design. I have schematic & placement for reference. I have connected multiple slave device independently isolated and non isolated product , its working well. There is...

    Dying for a 1 wire switch IC similar to Maxim DS2413

    Well , I was looking for a slave addressable ic for 1 wire protocol which can control a single GPIO. The RS2413 is the most right IC I could find suiting my needs (however I need only 1 gpio). But in my country, I'm having difficulty finding this IC, also, if there is a little cost effective...

    Need Help Decoding Automotive CAN Bus Extended Frame Bits

    Hi everyone, I don't know why but I'm having a tough time decoding CAN Bus data frames, even after looking at many sources showing bit field diagrams of how the data is supposed to be structured. Background on project/goal My main goal is to connect directly to an electronic turbo actuator...

    ESP32 SerialBT sending data rate is not stable

    Hi all, I'm using ESP32 model: ESP8266 with a built in BT module. I'm trying to open a BT connection between the board and an phone app with sending data rate of ~1-3kHz. I'm using Aruino IDE as a code environment and implementing the connection using #include "BluetoothSerial.h" library...

    RS-232 Isn't the TXD on Mark until the start bit?

    My first post, please pardon me if this is not in the right group. I have a USB-serial adapter using the FTDI FT232R chip. Specifically it is this item I bought on taobao.com. It is connected to a Windows 10 laptop. I connected the TXD pin to a simple oscilloscope. When I send some data from...
