E-10G RS232 HPC Modem

2010-02-24T06:36:00.000-08:00

First of all you have to build one cable adapter to connect the female 9pins connector of the modem, with female 9pins connector of the base of E-10G HPC.

To build the null modem cable you will need:

- 2 male connectors with 9 pins

- 15cm cable with 7 wires

The schematic at the left , its show how to connect the wires. When you finish it, you can connect the modem with E-10G.

When you build the cable adapter connect the E-10G with the external modem, power-on both devices and follow the pictures.

(Picture 1) Go to Start->Programs->Communications->Connection and click on new connection.

(Picture 2) Select “Hayes-compatible on COM1:” and then click on “Configuration”. Set the baud rate to 19200 (Some modems works with 115200 bps too. When you finish and everything its working, try to increase the baud rate until to 115200).

(Picture 4) Press the next tab and uncheck “wait for dial tone before dialing” and then click “OK”.

(Picture 5) Press “TCP/IP Settings” to set the “IP-address” and “DNS address” if your provider its need them. Click “Next” (Picture 6) , type the “phone number” of your internet provider and click “Finish”

(Picture 7) Click on “My connection”.

(Picture 8) Give the user name and the password ,click to “dialing properties”.

(Picture 9) Click “Bearb…”

Enter a “G” in all fields. Click “OK”, “OK” and then click “Connect”.

Troubleshooting

- If the E-10G cannot communicate with the modem, look the “wait for dial tone before dialing” option (Picture 4) to be unchecked.

- Then decrease the baud rate to 19200 (picture 3).

- If it’s not working, try to connect manually, by checking the “manual connection” option (Picture 3).

Try to run the “My connection” again and you will see the terminal screen( Picture 12). Type “atdt” for dial tone or “atdp” for dial pulse and then the phone number of your internet provider ( example: atdt0962599999 ).When the modem its connected click “OK”.

USB into Microcontroller Igor Atmel-USB device

2010-02-24T06:31:00.000-08:00

Purpose of this article is to inform readers about implementation USB to RS232 converter into singlechip microcontroller, which this interface directly not supports. Simply: implementation USB interface on firmware level (similar as emulation of RS232 interface in microcontrollers, which not have RS232 support). Given project is the next follower of my project of basic USB module IgorPlug-USB (AVR) (computer remote control IgorPlug with USB).

For use in user applications I developed improved USB to RS232 converter (+ another interfaces) with next features:
Device is intended for embedding into your products (source codes of firmware and software is free). For better choice I have prepared two versions, which are different in used processor type. Simpler version is based on AT90S2313 processor. Improved version is based on ATmega8 (see and read bellow its features).

Receiving FIFO buffer :
- AT90S2313: 32 byte FIFO
- ATmega8: 800 byte FIFO

Communication speed and link parameters:
- AT90S2313: from 4800 baud to 57600 baud, 8 databits, 1 stopbit
- ATmega8: from 300 baud up to 115200 baud + possibility to change databits (5,6,7,8), stopbits (1, 2), parity (none, odd, even, mark, space)

Additional build in interfaces and possible extensions:
- AT90S2313:

USB converter to 8-bit input-output port : each pin can be as input or output, option of pull-up resistor on input pin
USB read/write into internal data EEPROM memory : 128 byte EEPROM to store own data (e.g. calibration data of your product)

- ATmega8:

USB converter to three 8-bit input-output ports (16-bits together) : each pin can be as input or output, option of pull-up resistor on input pin
USB read/write into internal data EEPROM memory : 512 byte EEPROM to store own data (e.g. calibration data of your product)
eventually possibility to use ATmega8 peripherals (not yet implemented):
- 6-channel AD converted: 4x10bit + 2x8bit
- PWM channel
possibility to add own functions: cca 3K memory words (from whole 4K words memory) of Flash is free for next user extensions - specific functions (crypto functions for hardlocks, USB to "something" converter - e.g. USB<>I2C, USB<>PS2, ... . )
eventually possibility of firmware upgrade through USB (now not implemented - project for another developers :-) )

Application access:

Device communicate with user application through driver DLL library: is possible to communicate from more application in the same time (advantage with comparison with standard serial port)
Receiving buffer is exclusive for whole system - received data from RS232 are delivered to all communicating applications (every application obtains all received data)
Receiving of data is in one thread in DLL library (this receiving thread is only one in system)
Transmission of data is designed for use in control process - synchronous transmitting: after the transmit function call to transmit buffer is control returned back from DLL when whole buffer is transmitted (including last stopbit of last byte). This behavior is proper in handshake communication (and main advantage towards to classic Windows COM port).

Practical experiences:

Up to speed ~~14400baud~~ 57600baud (improved own driver) is possible continuous receiving - FIFO buffer is not increasing (transfer from device to computer is faster as RS232 receiving transfer)
Above speed ~~14400baud~~ 57600baud is receiving possible up to FIFO buffer size - FIFO buffer is filling (transfer from device to computer is slower as RS232 receiving transfer) and is necessary some pause in RS232 receiving to transfer data from FIFO to computer. So in case of handshake communication at high speed is necessary using data packets with size smaller than FIFO size (this condition is in practically mostly fulfilled - 800byte FIFO inside ATmega8 may be enough for everybody ;-) )

And here is example: my testing application "IgorPlugUSBdemo.exe" (receiving of file "msdos.sys" from RS232 terminal TeraTerm.exe):

Next information will be frequently added (last update: 20.10.2004).
Whole project will be in future accessible on webpages of Atmel company as Application Note. On the following picture is Project structure (source codes, firmware, binaries, documentation, ...) :

>> The schematic diagram of USB AVR In-System-Programmer

The circuit.

Following the schematic diagram that I read in the FT232BM manual I made the connections between ATtiny2313 and FT232BM. The FT232BM requires a few and ordinary components to work. When you connect this circuit to your PC you will see the message " a new hardware was found" and then the factory name of FT232BM. IC1 is a serial EEPROM that used to store user's settings. So, you can rename this programmer to be appeared as "AVR In-System-Programmer" or "MyAVR programmer". Furthermore, you can add the firmware version of your circuit. Of cource, you can bypass this component because it's optional. I saw that the programmer works with or without this EEPROM. Anyway, FTDI suggests you to use this EEPROM. Led D1 flashes when data are transmitted or received by FT232BM. CN1 is a USB-B connector and CN2 is a 6-pin connector to your target AVR (it is connected to the AVR to be programmed). The S1 switch is used to supply your target circuit with +5V from the USB connector of your PC. In this case you won't need any additional power supply for your target circuit. Consider that a single USB port can supply up to 500mA current. You should not exceed this current limitation including the current that needs your AVR programmer too.

Programming the ATtiny2313.

Burn the ATtiny2313 with avr910_2313_v38c.hex file. Do not forget to deselect the "Devide clock by 8 internaly" option and select the "Ext. Crystal Osc. 14CK + 65ms" option on fuses section of your AVR programming software.

>> Configuration tool for the EEPROM of FT232BM chip

Optional: Configure the USB programmer.

As I said before, you can configure your programmer to be appeared with the name you want. In this case, my programmer is appeared as "AVR In-System-Programmer" when I plug it in to the USB port. Note that if you change any information on this screen you should change the same information in the "FTDIBUS.INF" and "FTDIPORT.INF" files. If you don't make any modification to the EEPROM and you have Windows XP SP2 or newer operating system, you won't need any driver. All the necessary drivers are included in your operating system.

The AvrOspII programming software.

The programming software that was chosen is AvrOspII V5.47 (currently version) because it supports a lot of AVR devices and the author of this software Mike Henning is keep on writing new versions supporting new AVR devices. You can see if there is a new AvrOspII version available Here.
