Hello,
I'm new to this topic, so please bear with me.
I'm trying to come up with a prototype which will be writing ~70kB/sec of data using ultra low-power MCU (well, that's that idea). The amount of data is up to 256 Mb. I googled and the best I found is Macronix products, for example - this...
Hello,
I have a circuit that produces a square wave (can be varying duty cycle) with a maximum frequency of 1 KHz. I wanted to measure the signal through a ADC and feed it back to a raspberry pi to plot the data ( monitoring feature).
what should be the frequency sample I need to try and...
Hi! I am trying to establish a SPI communication with an LIS2DE12 accelerometer. First, I would like to say that I have checked phase, polarity, msbFirst and CS. I am using an EM9304 as the master of the communication, and the spi clock frequency is aproppriated.
Writing or reading from the...
Hello,
I am working with TOSHIBAs NAND flash memory. I am using standard SPI protocol to communicate with it. The datasheet is in the link below. I am trying to understand and solve two problems:
1. I do not understand what exactly is the column address of a NAND flash memory. On page 4 of the...
Hi, guys I'm working with MCP2515 CAN Module and PIC18F series.I write a single byte data and read it back using SPI Protocol.
But I am unable to receive any data back.
here i have posted the code please check it and help me.
i connected two MCP2525 modules , so I think there is no problem with...
Hi Guys,
I have a doubt regarding PIC Interrupts, I am using PIC16F887
I am Using Timer in Interrupt which Blink an LED for Approx 180 ms, and Sends Data through SPI when Certain condition occur,
Lets say when i am sending data in SPI and Interrupt occurs what will happen to data that is being...
I don't know where to ask but I was wondering if someone here has worked with it and could give some idea. Hope so.
A module ( MFRC522 ):
Schematic:
An MCU ( PIC18F452 ) is powered with 5V, module is powered from 5V(DC) -> 3.3V(DC) converter and all logic pins ( SS(SDA), SCK, MOSI, MISO...
Hello all,
I'm in the beginning stages of a project and am just learning how to use an Arduino Uno with a MAX7219 driver with an 8x8 LED RGB Matrix.
I'm using someone's source code to just get a basic understanding of how to put all these pieces together and will then modify it as I need to...
Hello
Here is another clever circuit that will create cool effects for a large array of smart pixels.
Objective:
Low cost circuitry
Easy to built and implement
No fancy bitbanging and worrying about timing constrains
Utilize any WS2811 based controller for RGB Lighting (Single Wire SPI)
Be able...
Objective: This circuit converts a 12V common anode biased RGB (or single color) module to a smart node with simple and low cost components.
Interface allows color control of individual RGB modules and control of many pixels via common WS2811 based controllers. (512 colors)
The 4-wire RGB+...
OK. I have just spent the better part of the day banging on this project and have found something that is either really irritating and incredibly frustrating or is a serious problem for oshonsoft, or I may just be an idiot and need help.
This is the story...
18F4520, 8MHz internal osc. LCD...
