    Uart baudrate question

    "Are you attempting to "recover" data previously recorded with a RX BAUD rate of 19200 and TX BAUD rate of 9600? " This is correct

    Uart baudrate question

    Hello forum. i have a question regarding the possible convert of the baud rate. Example: I recorded data with the speed of 19200...but the data was coming just with 9600 speed..it is possible to convert the recorded data to get the correct data? if yes, how? in theory i belive is...

    maximum uart baud rate for microcontroller?

    hello,how can i calculate at what baud rate can a specific microcontroller uart module can run? i realize that is a clock dependent feature..so ..the higher the clock, the higher the baud rate can be set...so ..how can i calculate ? thankx

    16f to 18f code migration/optimization

    I want to use it at maximum speed that a actual PIC can do it , with a external 64 MHZ OSC..on the 877a i was using 20 mhz OSC. The program reads serial data by interrupts ,and outputs it via uart..running on real hardware , no simulation. Thanks

    16f to 18f code migration/optimization

    unfortunetly, MIcrochip does not provide TEMPLATE file for 18f25k22 :( ..I`m moving to 18f due CPU speed concern

    16f to 18f code migration/optimization

    The CONFIG OPTIONS are seted in MPLAB menu "CONFIGURE BITS" and they are deleted from code...so this is not the problem...I`m suspecting maybe a TMR0 problem? in regard that it must be set properly to 8BIT mode?

    16f to 18f code migration/optimization

    Hello. I need some help regarding the migration from the 16f877a to 18f25k22 device..i had modified all the registers acording to the datasheets but my program wont work on 18f25k22, but compilation is successufuly . I`m using MPLAB V8.8. The project forward the data from a eusart line ,and...

    Interfacing eeprom 16f877a

    hmm..i-m not bound to SPI . I could use I2C also...i need some sort or routine to move the data from "d1" in the external eeprom. Thanks

    Interfacing eeprom 16f877a

    First off all Hi. My name is Maria and i-m new to microcontrollers. I have a project made in ASM unsing MPLAB with the 16f877a controller. The device forwards the serial data from a gps module and send it trough the RS232 port on PC , at a speed of 57600 ,over a FTDI cable in real time. What i...
