For analog PSTN modens, have two options: 1?: serial interface - rs232 "physical pattern" 2?: Parallel interface - TTL "physical pattern" For the first option, do You need build one interface for conect the microcontroller/modem. In second option, if Your microcontroller are powered with 5 volts, no (...)
hlo bro i'm from Indonesia and need help from other master heheheh now i've worked in my last project to graduate from university i want to know the code to interface to serial interrupt in ATMEGA8535 that when i send a character from PC to micro will back to PC that seen in the hyperterminal i see in the post zhi_yi but in that post seen th
you don't have the option of USB with PIC18F452, you can use serial interface, read the datasheet about the built in USART module, you will need MAX232 IC with some capacitors for line coding. also the parallel port available, just you will program the parallel port pins and make it read/write from any GPIO pins of the microcontroller. for USB yo
Most modern PCs don't have a parallell port, so if I was you, I would use a serial interface which is easier to come cross in the modern world.
I would almost bet that u need a usb host capable MCU, else buy a cheap cellphone with serial interface (rs232) like old motorola/siemens or try nokia FBUS.

Here Is AN Application Note From SunDisk About Interfacing CF To serial Port With 6811 UC
Questions: -speed requirements ? -security ? -power consumption requirements ? -data or voice (i guess data because of -51) -price target ? And of course it must be legal. Frequency bands are country dependant. Perhaps some of the ISM-bands will do ? Many manufacturers exists. serial interface is convenient to use and there are ready mad

hi friends i am using a 16x 2 lcd having parallel interface .i want to make it serial interfaced. what to do? serial lcd are not available in my area. can i use some parallel to serail converter chips bye
Dear hm_fa_da: When you asked about serial interface, I thought about an UART interface; in this case, the answer is yes. The rs232 standar, specifies only the "physical" layer of the interface, that is voltage levels, threshold, etc. When you connect two or more MCUs, SPI or I2C (...)
hi .. I want to test a serial interface ... and to make things easy I assumed that the two devices are PICs ( I know that we don't need a serial connector to connect them , but the aim here is just to test the serial connection whatever the devices are ) I was confused with the connection , so I drew it and need (...)
i have spartan3 fpga starter kit from xillinx i want vhdl or verilog code to interface with ps/2 and serial (rs232) thanks for any help
Hi, yes has a many different solutions. First is the RS485, this is classic solution for your problem, this is a multi client serial interface. Another choice is a multidrop rs232, but with high voltage. Other decision is a low speed optical network, with aglient trancivers and plastic fiber optic, the price is very good. If you have only (...)

I have a transceiver module that uses either one of these host interfaces: 1) MII PHY 2) GPSI PHY 3) MII Host/DTE I understand with the 1st one, MII PHY i'll have to use an Ethernet PHY transceiver. I have located one of such transceiver, the KENDIN KS8721B. However, i do not know how to construct it. The datasheet that i managed to obtain
There aren't rs232 to Usb converter in . Believe me or not, there are. scroll down to CP-US-03 USB to serial Adapter But probably you need one that covers new OTG (Limited host capability to communicate with selected other USB periphera
Hi scgoo! You haven't posted the complete code. Check the serial port initialization registers in pic and set appropriate baud rate in pc as well. Giri
Hi, I do need any tutorials or books about industrial networks. I wanna gain knowledge about the communication between any logic processor ( DSP , micro controller )and the PC as well as the rs232 and the RS485.from where shall i start ? it would be helpful also if anyone can recommend any site .. I work with Dallas
As mencioned above you just need a MAX232 and a few capacitors to connect the PIC to the PC using serial coms. Most of C compiler already include libraries for serial com.

hi . im oso doin a project in rs232 need the codes to control serial port anione? or u hav it? visual basic
Hi, Just curious, did u find such a module? PoE + Ethernet to serial interface. Thanks
This may do things rather difficult .. You see, information is usually coded in numbers and not in the presence or absence of a signal .. And to ?decode? a serially sent byte one needs some ?intelligence? which is easily provided by even reduced-pin microcontroller .. For simple tasks like you just mentioned in your post I would go for a simp

Hi,Regards I want to send a varible to the pic with rs232 i think first you need to establish serial commuincation... by the way how you are checking code... directly on circuit or simulator..???
hi there! I've built an ICD2 clone that have both interfaces: USB (pic18LF4550 as bridge) and rs232 (pic16f877a as main controller) It's just a potyo2 with a max232 and a db9 connector each pic (f877a and lf4550) has its own 20mhz xtal the serial interface works well, icd2 can connect, download os, program, (...)
Hi I have a very, very basic and simple question about the rs232 interface. Basically, I have a microprocessor running with 24 MHZ and sends and receives the data over the RX and TX Pin respectively. How do I need now to select the baud rate at my host PC to be able to communicate with the microcontroller over the serial (...)

hello everybody.I want catch directly 1Hz frequency from pin's of com port (in other word if i connect one led directly to the serial port it regularly on and it operative and how? Man .... U r using which type of serial comm rs232 .... then to check that ur serial port is working or not just short pin nos 2 & 3
Hi beeshyak, Yes, you are right. Sorry that I have misinterpret the question. What shivachellam could be asking is can VB codes communicate to a microcontroller. Yes. A computer can talk to microcontroller through many means. digital I/O, parallel port, serial port (rs232, RS485), Ethernet, WiFi. for rs232, you can try searching for (...)
Hello I need to transmit serials datas RS 232 ( 19600 / 8 / N / 1 ) over 1500 ft distance ( 500 meters ) and i found RFM12BP module from Hoperf. This module has SPI interface and i don't know how to convert my serial data ( rs232 ) to spi . Has someone already done that ? I will really appr
Hi, I planing to use any PIC micro (for example 16F877, 876...) with nokia 3310First, make sure this phone has a serial port and supports the 'AT' command set. You may want to consider using a GSM module instead. I want to send SMS to this mobile for opening and closed electronic door (if is possible with one
I think you might not have initialise your USART. You might like to read more about rs232 in order to understand and setup a simple test step by step to troubleshoot the source of the problem. Best Regards, Siong Boon
For A1200 ALPHA meter from How can I do CLO (current loop interface,between pins 23,24) interface with PC serial port(rs232)? Do you have CLO to rs232 converter schematic?
First of all, select nokia mobile phone with serial port rs232. onces you have selected the mobile, search your mobile's cable datesheet. short all pins(of ur data cable) except Tx,Rxand GD. Search google for At command and serial port
It’s a complete mismatch .. Using hyperterminal you have no control over particular pins of the serial port and on top of that to get data from MAX187 you need to follow the exact timing sequence .. see data sheet .. It can be done with the parallel port, but really more practical approach would be to employ a microcontroller, program i
Been given a task to write program, software and hardware design to READ/WRITE EEPROM, 24LC16B EEPROM. PC ---> uC (16F877A) using rs232. Using normal serial cable.
