ChibiOS Free Embedded RTOS

Thank you Giovanni. That is very helpful and I managed to dig up the pages in the STM32F4 reference manual. That manual sure is a long one!!!!

Best, Mike.

Hi,

I have a Olimex board with a STM32F4 chip on it. In the documents it says it can run at 168Mhz. But I understand that this is configurable by changing / setting some registers. I have the following newbie questions:

1) The Olimex STM32-E407 board has a "Canned" set up in Chibios 2.6.2. Does ...

Hi,

Success!!! I now see:

Hi,

Made some more progress. I think I am now sending out some UDP messages using this code:


/*
*
*
*/

#include "ch.h"
#include "hal.h"
#include "chprintf.h"
#include <string&#46;h>

#include <lwip/netif&#46;h>
#include <lwip/ip_addr&#46;h>
#include <lwip/tcpip&#46;h>
#include ...

Hi,

You are correct. I made a bit more progress and the thing I needed was to use tcpip_init(). This solved the issue. lwip_init() is called by tcpip_init. I was using UDP so thought that I did not have to use any calls to tcpXXX. But this is not the case. I also think that other users may not ...

Hi,

I am trying to send a short message via UDP as a broadcast message. However my call to netconn_new returns a null. I traced it through and it fails in Chibios sys_arch.c line 189 which is the check to see if the mbox is valid.


int sys_mbox_valid(sys_mbox_t *mbox) {
return *mbox != SYS_MBOX ...

Hi,

Success!!!!

Thank you for all your kind help. I think the issue was I had my Mincom looking at /dev/ttyUSB0 when I should have had it look at /dev/ttyUSB1.

Warmest regards, Mike.

This is what I get out of my Minicom:

Hi,

Thank you for your kind help. I think I am making progress. I went home and gave it a go. I think that the Serial Driver on SD6 definately does something. The reason I know is that on my Linux box I see /dev/ttyUSB0, then when I start the program Minicon complains that this device does not ...

Hi,

I am a complete Newbie to ChibiOS and hope this question makes some sense.

I have a Olimex STM32F4-E407 board and I also have a Olimex MOD-RS232. The
Olimex MOD-RS232 is a board that converts 3.3v to 5 volts for RS232 signals.
The MOD-RS232 I have connected to a Flyswatter2 OpenOCD interface ...
