I configured the ISR to be triggered with the rising edge and within the ISR changed the configuration to be triggered on the falling edge hoping to catch the second edge of the same pulse, but I didn't get the ISR again , I'm not sure why
Hello All,
I'm trying to measure the time of an external event staying outside this controller MPC5746C.
This controller supports only the detection of the external interrupt on either the rising or the falling edge.
Assume that I configured a pin to be used within the SUIL2 module to detect...
Hi All,
I'm confused about how Ethernet stack works exactly if we have an application needs to send a 20k message via tcp protocol where:
1 - in SoAd module, shall we create a buffer for the 20k message?
2 - is the 20k delivered to the Transport layer? is there any allocated buffer in that...
In Ethernet networks, the MAC layer is the first layer to detect the destination address of the received message.
my questions: is that means that the transceiver shall take a copy of each message on the bus and forward it to the MAC layer who will decide to accept that message or discard it...
Hi All,
what is stated in the standard for ARP Protocol,
If the Destination is not exist, shall the sender sends the arp request for a specific time or shall it retries the for a specific number
" please provide your answer from the standard"
Thanks in advance
hi all , in C :
if i have an array contains repeated scattered items , and i need to make this array has no repeated elements but i ,must use only one for loop , how can i do this ?
@andre_teprom
regarding Const variables : i know what you wanna say that we can with syntax store any variables in any memory
with using keyword eeprom and flash at the variable declaration but this answer deviate little away from my question
const int var=10; question is : is var...
microcontroller flash memory divided into
code segment // to store the code itself
.rodata segment
startup segment // to store the startup code
my question is
where are the locations of the literal string like
if i define char array[100]= " hello every one "...
hello all;
i know completely Concept of semaphore and mutex and difference between them
but, i don't know how they implemented , are they both disable interrupts and scheduler to implement exclusive access in critical regions or what ?
hi all
I'm so confused
we know that all functions defined as global so we can call and use any function inside any block without passing it as argument
why we use Function callback concept while we can use a function inside any function without passing it
so why we use callback concept ?
why we need to use RS ? if we need to make a communication between two Micro controllers containing UART modules why we don't simply use two wires between the uart module?
still i'm so confused about differentiation between Rs generally and the protocol itself
e.g
if i wanna to make serial comm between two MC's with UART where and what is the role of the uart module as a h.w device and the role of RS
hey all
i need some help please
i know that UART is a h.w device represents a communication protocol
but
1 - what is RS-232 ? is it protocol ? or just interface ? what is meant by interface ?
2 - if Rs-232 is interface for serial communication why we can't use it with SPI , I2C ?
3 - if...
