rather use usb serial converter,which comes at almost same price as FT232. apart from that the IC comes in SMT only.so,its difficult to make the circuit at amateur level.
hey 'nandhu015', i've managed to multiplex my programmer and data logger both on same port without any external hardware. for that i have to study my programmer circuit, which involved TX pin(PC side), while RX pin was free. so i used that RX pin for data logging. so no need to use relays or...
i know that usb-serial devices are available, but being an amateur(?) electronics student, i want to know whether it is suitable to make port-switching circuit or something which involves buffers or 'relays' as mentioned by nandhu015 before. there is no fun in buying readymade devices.
Re: Urgent : How to Convert Serial Port Data to USB data
i want help with the first solution.
i wish to program a microcontroller using serial port programmer. also, i want to use same serial port for data logging from same microcontroller. i want some kind of switch so that i can use my pc...
Nokia and samsung mostly use ARM9 or ARM7 processors.
TI came up with OMAP processors which is used in most of the nokia N-series phones as well as some android phones.
Hi all,
i am participating in a competition where my autonomous bot have to differentiate between two types of block(essentially placed on the intersections of a grid) & deposit one of them at target position, avoiding contact with other type of block. sensors will take care of differentiating...
@pranam77:its not that i am weary of issues posted by you, just wanted to get my hands on PIC, which is supposedly a different kind of thing(or rather which is used in industries etc.) i think(regarding what you mentioned),if need arises and if pic's are available i can safely continue my work...
i am an avr person, i,ve by far used atmega in every project of mine. Plz anybody can suggest pic ic's which are equivalent of atmega8 or atmega32 ? i also expect some explanation over their nomenclature, which is much more confusing & look one & same.
i've made a line follower robo with atmega32, the robo works fine, but one thing i observed is the power LED on mainboard of bot blinks at a low frequency while bot is running. supply is same for mainboard(has atmega32) & motor driver chip, which is around 8volts. while surfing net i came across...
Problems with USBASP
i had used usbasp earlier, belonging to one of my friend, now when i tried building it myself i am getting usb hardware not recognized error. i checked with circuit connections zillions of time, no connection error, swapped D+ D-, but no relief. checked with zeners which...
Atmega8 LCD problem
hi,
i m using atmega8,11.0592MHz and 16x2 LCD . whenever i write a simple prgm in codevision for displaying something(e.g.constant string like my name,using lcd_puts), it shows it properly.
But when i create code for my main objective(including timers,ext interrupts,adc and...
li ion battery charger
i want my bot as light as possible, so i headed for li ion (one which is used in nokia phones). now i need a good reliable charger circuit which take cares of overcharging and such things. also it should support 2-4 such batteries,it can be usb powered or separate ac/dc...
using this code(which is also given in datasheet), i m not able to receive in terminal for simple echoing program(especially d one wrote in ICCAVR), in codevision i used standard library functions getchar putchar, but having problem with the above given code.:?::?::?::?:
