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
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.
1 Wire to serial interface Circuit using max3232E IC, This interface can daisy chain 1Wire device such as 18S20 Supply Voltage 5VDC, (schematic / ready PCB is available ) 77383
PC Battery Charger An unused serial interface port can supply enough current to charge (or trickle charge) lowcapacity Nickel Cadmium (NiCd) batteries.
The trick is in differential mode. The faster serial buses like USB, firewire, ethernet etc all use differential pairs for data. Differential mode offers a lot more noise rejection besides cancelling rise / fall time delays. If a parallel bus is designed with differential signal, it would be too expensive. But you can get very high data speeds.
anybody could tell me about the VHDL 'serial interface Engine' ?, is it possible to get the VHDL sources? where? Thank you
Hi, For serial interface such as on KS071X series. Is it that only the display data cannot be read back from the on-chip ram or the status(such as busy) information too? "Set Static Indicator Register", how to use it? Is it use for blinking an icon on the lcd display? but how is it related to which icon Thanks. Reg
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.

Hello I want to implement an serial interface for my design but an High speed case with more than 10G @ 200meter I've found LVDS but it is working near 100Meg @ 10meter 422 hasn't enough speed what about 10G Ethernet? what about Fiber Optics based solutions? I am not aware about latest technologies here.... Thank in advance

You need an FT232R USB to serial IC.
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

Hi, I am trying to implement a DDS on a FPGA and I need a serial interface to program the registers associated with it. For example the incremental phase and the start phase may take 2 x 48 bit registers or 12 x 8 bit registers. A second DDS will have more registers. I found several VHDL implementations of SPI slaves. But they seem to handle o
Hello, Can anyone help me with a sample program for a serial interface of a printer with a Microcontroller. Thank you.
I2C or 2-wire serial interface cant be full duplex its either Master transmit or master recieve , or slave transmit or slave recieve . it requires start and stop bit generation to start and end transmit and acknowledge sequence from the master or slave for sucessful recieval of data .
Hello, as mentioned above, I need a schematic of Ademco / Honeywell 4100SM serial interface or the schematic of a compatible interface. The connection to the alarm base station semms to be a serial interface, but I am not sure about the level converter and about the question if the signals are inverted. (...)
We experienced the same problem before when we were trying to find a suitable cell phone for our project. The most suitable one was Nokia 6610 as it has a serial interface (rs232) and support text mode messaging. With the Nokia 6610, all you need to do is to connect the TX pin of the cable to your RX pin of the MCU, the RX pin of the (...)

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 (...)
Hi, Is there any 8bit MCU out there that can be programmed/re flashed just using a PC's comport? All of them seem to require an external ISP. If you know any mcu family that has a serial port based program that sits on the MCU and enables in application programming via the com port, LET ME KNOW ! :D
Hello Please can someone help me to get the SRF02 ranger to register correctly by sending the correct distance in CM. At the moment it is only replying back '0' and its LED flashs according to my program loop. First I used the ranger via I2C interface and that worked well. Now I changed that to serial interface via changing tie (...)

Just a 2 cents idea: Use a CPLD to convert your serial stream to parallel. As an example a simple EP3064 from Altera would do the Job. Aantage: - A CPLD could have a state machine which would initiate your LCD at startup. - It would take care of the low level handling. - If you change the LCD in the future, you won't have to modify your h
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 (...)
