i am using keil MCBX51 board my project requires 2 serial port i am using ext serial port for monitor and i am left with int serial port only but i want 2 serial port
what to do plz.. help me friends
how can i acess ext serial port, how to config it
thanks friends
in my project i hav to receive a data frame from serial port and modify it suitably, then send it over serial port.
"those relate to the '51"
The question arose in an 8051 context, but the answer is generic - here's the list:
- get a 2-UART derivative plus some of the solutions below - switch the 1 internal UART (if data are not simultaneous) - softUART if not too high speed and you know exactly what you do - use parallel interfaced external UART - use SPI/I2C interfaced external UART - use a "slave micro" interfaced via I2C/SPI
All of those could be applied generically to any processor.
"the MCBX51 ... is a 251 board"
No, it's a generic board, supporting both:
"The Keil MCBx51 Evaluation Board works with all 44-pin 8051 and 251 devices ... allows you to investigate the capabilities of the 8051 and 251"
http://www.keil.com/boards/ http://www.keil.com/mcbx51/
those relate to the '51 (which the OP erronesously refer to) I had a peek at the MCBX51 and it is a 251 board. Since I rejected this pittiful attempt at a "16 bit '51" long ago (just have a look at the XA), I do not recall if it has two UARTs, but it may.
