ARM: How can I use lwIP tcp/ip stack with microcontroller stm32f4 (client)
Core: Cortex-M4
Microcontroller: stm32f407 (stm32f4 discovery board)

I am using this microcontroller to control an automate and I want
to send some information to a separate web server via a HTTP request
in the form of:
http://192.168.1.3/api/xdevices.json?SetR=01
lwIP has a http server for the microprocessor, but I'm after the
opposite (microcontroller is the client).
I am not sure what i'm doing wrong but after TCP_Connect it

ARM: Debugging - Save register (or variable) content to a file (2 Replies)
Hi,
I would like to know whether there is any way to save the content
of a register (or a variable) to a txt file in my PC for debugging
porpuses (plot the data). I am using Keil uVision 5 and the STM32F769
MCU and in my case want to save the content of the DAC->DOR1
register.
Thanks in advanced,

ARM: Splash screen (6 Replies)
I've written my code and it working perfectly but I now have one
problem.
When it starts it doesn't go into main. It goes into my screen
splash code and shows a picture I don't want. How can I get it to
show the picture at the right time.
This is really annoying because I have looked for a bug for more
than 30 minutes but the code is perfect.
I cannot waste ant more time on this problem. I will post you the
code. Can you check it urgently for me.

ARM: FMC problem (1 Replies)
Hello Every one,
I am starting a new project and I am using the FMC peripheral in
order to communicate with a LCD TFT. I have configured the pins in
the STM32cube mx ,and checked on my board the pins to be connected to
the LCD (16 bit MCU).
I am using a STM32f429 VET processor with Keil MDk5 version. The
problem seems unexplained and weird, because I am trying to write
data on the FMC ports and I don't receive anything. I used a software

None: Multiple instance of thread function (1 Replies)
Hi,
In keil.
void taskThread(void const * arg)
{
}
osThreadDef(taskThread, osPriorityNormal, 1, 2500);
I want to use same function for multiple instance of osThreadId (
for 2 or more threads).
Can I attach function to thread at run-time.
So I can wrap in my C++ thread class and use thread class multiple
instance. which can create multiple threads.
Thanks,
