    Detecting unknown baudrate

    Hey guys , I have trouble figuring out the logic for this problem statement:there are 2 atmega328 one transmitting data at an unknown baudrate while the atmega I have to program to detect the unknown baudrate ,I know that if there is baudrate mismatch there should be error but what kind error...

    MSP430g2553 ADC not working

    Hey got my new msp430 lauchpad was working with adc here is simple program to get the analogue value from P1_0(A0) convert it and output it to Port2 but I not getting it to work after looking inot datasheet and sample code too.The ouptut seems to high all the tie I vary the potentiometer from...

    2 layer pcb beginner doubt eagle

    Hey guys I am making a arduino mega (2560) shield which consists of 4 dip ICS and some capcitor and 4 (8pin row)screw terminal ,so im using basically all through hole packages soldered on one.The problem now is that the circuit is big so it cant fit on a single sided board, so I have to build...

    beginner doubt ??????

    Hey guys in my project I need my atmega168 to drive a 24V relay(30mA,1100ohms).I am using npn transistor which will satisfy the current requirement of the relay to turn it on.The problem is that one end of the relay is already grounded so I cant really use CE configuration and i am quite...

    arduino mega 2560 and hmi

    Hey guys,I am working on a prototype of a bike wash machine which consists of HMI DOP B series here's the link to the manual https://www.deltaacdrives.com/deltadop-b05s111-human-machine-interface and interfacing to arduino mega 2560.The Hmi would consist GUI in the form of buttons,user would...

    hmi touchscreen interfacing with microcontroller

    hey guys im trying to interface plc-hmi(touchscreen) with a microcontroller **broken link removed** this is the hmi im using it has as 32 bit mcu inside it.i have read that it can be interfaced using modbus protocol like is there another way out they provide RS232 port

    systic timer problem???

    hey i am using systic timer to blink a led my core frequency is 100mhz so typically between 2 interrupts there is 1ms accordingly i have to tried to blink led but to no avail am i missing something #include "LPC17xx.h" #include <stdint.h> volatile uint32_t msTicks = 0; volatile uint32_t...

    [AVR] help in programming of atmega 16

    you need a programmer(there are many cheap programmers available) to flash the controller and if you want to check whether your code is functional or not you can simulate your code to find it

    keil mdk-arm problem

    im using keil mdk arm to create a application for lpc1768.MY probem is that when i simulate and single step using f11 the registers in peripheral window do not update i dont know why suppose i single step through this instruction LPC_SC->PCONP |= ( 1 << 15 ); // power up GPIO Pconp register...

    small doubt regarding register??????

    hey guys i have a small doubt here how is a 8 bit data saved in 32bit register(lpc1768) :-?

    lpc1768 core speed??

    i have included the system_lpc17xx in my program now when i begin simulation the cursor runs onto the system_lpc17xx.c file rather than my application code is it right (and surprisinglywhen i simulate system_lpc17xx.c the core clock is 100mhz)

    lpc1768 core speed??

    thanks alexan the code is right i confirmed the problem is with simulation like one of the condition consists of read only register(PLL0STAT) it is iset in hardware only while (LPC_SC->PLL0STAT&0x04000000==0); so how can i simulate it in software like this condition will be true in software always

    lpc1768 core speed??

    thank you alexan for your reply,i understood the formula have set the parameters accordingly manually as im not getting dialog box as you are getting im using keil mdk arm version 5 .Now i have written a program which configures pll void setpll() { // the crystal oscillator is 12 MHz // main...

    lpc1768 core speed??

    i written this code to set core speed to 100mhz is it right #include "LPC17XX.h" int main() { SystemCoreClock=100; SystemInit (); } and another problem is that while simulating i single step and get stuck in this loop forever while (!(LPC_SC->PLL0STAT & (1<<26)));/* Wait for...
