Hey Guys, I was wondering if it was possible to run more than 3 serial ports off of a gumstix/robostix configuration. Is there some sort of external serial splitter/replication that will mux two signals into one. I would like to have 4-5 serial ports using the gumstix. I am also using the bluetooth module, so that hogs on of them. Thanks, Nate |

you could also use the i2c to send stuff to the robostix and it could send that over the serial...but that's lower bandwidth because of the i2c bottleneck.

If you could implement software serial on some GPIO pins on the robostix you could make the gumstix talk to the robostix via one of the uarts. Effectively the robostix combined with some code on the gumstix side would be the splitter/mux you (Nathan) described. Arnar |

Why should i use Rpbostix when i have the ability to build my own Expancion Board. I any case i think it will be allot faster with a serial from Gumstix communicating directly to another mcu and from there to send commands through the pins of the MCU to other boards . It's just that i have 13 boards with which i need to communicate and it's for a project and not a personal use so it would get nasty with all the wires and modifications on the robostix when i can build what i need nicely in one board :) Demetris Z. ----- Original Message ----- From: "Arnar Birgisson" <ar...@gm...> To: "General mailing list for gumstix users." <gum...@li...> Sent: Sunday, April 01, 2007 6:12 PM Subject: Re: [Gumstix-users] More Serial Ports > On 3/31/07, Jesse Welling <jes...@gm...> wrote: >> you could also use the i2c to send stuff to the robostix and it could >> send that over the serial...but that's lower bandwidth because of the >> i2c bottleneck. > > If you could implement software serial on some GPIO pins on the > robostix you could make the gumstix talk to the robostix via one of > the uarts.

The way i have it figured out is that i have a custom software on each board that waits for serial commands to be sent to it so it could do somethng. So i have one "MAIN" board that communicates to Gumstix through serial and when recieves data from it send's serial commands through one of the MCU's pins to other boards. So why should i use i2c ?

OK - I guess I don't understand your setup. If you only need to communicate with one device at a time, you could also use a mux/demux. Are all of the devices connected on the same serial bus? Or do you have 13 distinct serial ports? -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

I have 13 boards that are connected through TX-RX serial to a Microcontroller on TTL level. So 13x2 = 26 pins are used on a microcontroller. I send data to each board through those pins and they act accordingly.

There isn't much to say here. I have a PIC 18F4525 running on 40 Mhz. So it doesn't get too confusing i already programmed the chip to send particular commands depending on what Gumstix Send's to the MCU. So if i send "Go Motors" then Ports (Pins) 2 and 3 (for example) send out serial signal to the boards with the DC Motors on it.

I use 2 pins for each communication. And have 1 of the pins on each board Pulled to ground. So that the communication get's faster. It takes approx 6us from the time of a command being sent from Gumstix to actually get the responce on the working end.(Which is pretty fast for what i need) Having in mind that there are another 2-3 MCU's through which the command filters down and gives the action. ----- Original Message ----- From: "Demetris Zavorotnichenko" <fgc...@cy...> To: "General mailing list for gumstix users." <gum...@li...> Sent: Monday, April 02, 2007 9:21 AM Subject: Re: [Gumstix-users] More Serial Ports > There isn't much to say here. > > I have a PIC 18F4525 running on 40 Mhz.

Well the easyest way of doing this would be to have a Micro sit and wait on your MAIN Comm port and you would send a Start Byte let's say [11,Data]. So when you send this to the micro that will send your "DATA" to the pins (Serial 1) that you have. When you send [12,Data] it will recieve "DATA" from Serial 1. So if you would want to send to pin(Serial2) you would send something like [21,Data] and so on. ----- Original Message ----- From: "Nathan" <nk...@vt...> To: <gum...@li...> Sent: Monday, April 02, 2007 4:55 PM Subject: Re: [Gumstix-users] More Serial Ports > Demetris, > I'm building a robot, partly as a hobby, and partly as research.

I've found servo motors that provide feedback, the only problem being, they require another serial port. I might want another serial port for a magnetometer or other similar devices.

We're planning on semi-fazing out the "on-CPU" UARTs in favor of USB-connected UART controllers. ie we're planning on ending up with the FFUART being the "console" and all other "available" UARTs being supplied by daughtercards via USB-connected UARTs. Pros: * Frees up pins on the 60-pin connector * Allows for effectively unlimited number of UARTs * Removes confusions about setting GPIO alt functions right for various serial port combination uses * Allows all the control signals to be available on all UARTs (assuming the USB-uart chip does this, which many do) * Removes the need to disable output on the "console" port -- all "serial ports" are /dev/ttyUSBn and /dev/ttySn is defined as basically "for system use" Cons: * Slightly higher part count/COGS in situations where you're reproducing what exists now * Software needs to change /dev/ttySn to /dev/ttyUSBn (but we're talking about doing this on a new CPU anyway where other software changes are likely needed) Nothing imminent here, more kind of thinking on the next-gen gumstix after Verdex.
