    STM32F103VBT6 RTC Interrupt

    Hi, I am using STM32F103VBT6 micro controller, i have done a RTC code for date and time, But in that, I need to do a interrupt for every 1 minute. Is it possible to do? I have done some code, for interrupt . but its not working. How can i do interrupt for every 1 minute from RTC? controller has...

    4 to 20mA Current measuring Circuit Max 4072

    Hi, I want to measure unidirectional only. DC_Volt = 24V Ref_in = 2.5V. O/P is going to Micro Controller. I am using STM32F103RB. Maximum I/P range is 3.3V. So i used R45 is 1.5E.

    Current to voltage Converter

    Hi, i want to convert 4 to 20mA into 0-3.3 v range. I know about RCV420. but it needs negative supply. Anyone knows any ICS, which is converting the current into voltage other than RCV420? Thanks in Advance Akhil francis

    stm32f103r6 PWM output

    Hai, my name is akhil francis. I am using STM32F103R6 CONTROLLER. I am new to STM32 controllers. i want to generate pwm outputs from the controller, my doubt, is this controller has dedicated pin for the pwm generation.? or can we generate the pwm o/p through the any of the i/o pin by...

    [General] Thermal printer interfacing with micro controller

    Thanks for your reply. I am using "FTP-628DSL490" interface board also with this thermal printer. I guess this interface board will convert the TTL level into rs232 level. my controller has CTS, RTS pins instead of DTR and DSR. my doubt is what are the pins which i have to connect into this...

    [General] Thermal printer interfacing with micro controller

    Hi, Thanks for your reply. I am using "STM32F103R6" microcontroller. while reading, my understanding is for serial i have to use 8 pins for connecting the "FTP-628DSL490 " interface board with STM32F103R6 micro controller. 8 connections 1. RD 2 TD 3 DTR 4 GND 5 DSR 6 SLCTIN 7 INPRM 8...

    [General] Thermal printer interfacing with micro controller

    FTP-628USL401 , this is the printer which i am going to use. i am planing to bring the interfacing board also. I have the data sheet. but i need to know some theory about the operation. I am going to communicate with serial interface. How the strobes and latch signal is working, how the stepper...

    [General] EDE1400 thermal printer interfacing

    Hai, I have a doubt about EDE1400 IC. I read data sheet of this ic. I have attached the schematic of this IC with micro controller. by doubt is there is no connection to stepper motor. how we control the stepper motor? or no need of that? And from where i could by this IC? Please give...

    [General] Thermal printer interfacing with micro controller

    Hai, I am new to thermal printer. I am planing to interface fujitsu thermal printer with micro controller. In fujitsu data sheet i could not find anything more about code side. I dont know about the communication protocol between the printer and the micro controller. For serial reading should i...
