Hello guys,
Can we use Malloc or Calloc functions in Embedded C using keil ??
if we want a dynamic memory allocation then how can we done it in Embedded C using keil compiler.
Help me !!
-Thanks

Hi,
I am using keil u4 compiler. i want to use 8051 mcu for creating a small application.
but i am facing a problem.
if i open a new project window & create a new project, it will ask to select a device for the target, but the 8051 MCU is not in the list.
when i go to file->device database...
Thanks !!
int UART0_SendByte (int ucData)
{
while (!(LPC_UART0->LSR & 0x20));
return (LPC_UART0->THR = ucData);
}
while (!(LPC_UART0->LSR & 0x20)); /* this condition should satisfy when the Transmit Hold Register(THR) register should be empty. if not then it will be in infinite loop...
I would like to know answers for these Questions.
In that register if i set bit value 11 then, it will select as a 8 bit character length for the uart transmission. but as soon as you select value 11 how does the controller know it should transmit only 8 characters. should we write a complete...
Thanks for the reply,
This Questions are confusing me please clarify my doubt.
after initialization the UART, how does an uart rises an interrupt regarding a character has been sent or received ?? or
if i select a register in UART for 8 bit character length transmission, should we write a...
Hi,
There are few on-chip peripherals in MCU, such as ADC, UART, WDT, DAC etc..
Does these peripherals got a inbuilt software code in it ??
Ex: UART
How does an UART rises an interrupt to the MCU when a data is received from the PC (key is pressed) or when u place a data in its transmit...
Hey Thanks for ur reply,
I am using keil Cross complier.
Yeah its from NXP, i am using LPC1756 microcontroller.
Oscillator frequency = 12 Mhz.
and i am setting a baud rate of 39473, through DLL & DLM registers.
One more Question:
The on chip peripherals (ADC,UART etc..) in MCU have a...
Hello,
This my first thread please help me out..
can any one post a complete uart driver code for microcontrollers.
My basic doubt :
Ex: please find the attachment.
In that register if i set bit value 11 then, it will select as a 8 bit character length for the uart transmission. but as soon...
