Hi, Has anyone gotten the Olimex LPC2148 development board and IAR Uart example working for the LPC214X? I can see something with hyperterminal, however it is just junk characters. I have tried all available baud rates. Is this code possibly for a specific dev board? This is an initial test to get running, what I really need to do is get FAT16 talking to an sd/MMC card. Is there anything on that while I'm here? Thanks alot.

Verify your fundamental clock setting, it may not be referencing 12MHz. Keep in mind the LPC2148 has a fractional divider reg (FDR). You can find my tool for calculating very accurate baud rates for the LPC214x (FDR enabled devices) here: http://groups.yahoo.com/group/lpc2000/files/Tools/lpc2fdcalc.exe Also you should be able to find my port of the EFSL on the EFSL dev mailing list. It implements FAT12/16/32, serial, and RTC code. http://efsl.be/ Joel

Hi, First get rid of hyperterminal. It is very sensitive to faults in baudrate etc.Take a look at http://bray.velenje.cx/avr/terminal instead. /Ake stephan2148 wrote: > Hi, Has anyone gotten the Olimex LPC2148 development board and IAR > Uart example working for the LPC214X?

Hello again Joel, thanks alot for your tool. I have the uart code working. I would like to check out your port of the EFSL for IAR and the LPC2148 if it is available, this is exactly what I am trying to do. I however cannot find it on the mailing list. Do you know if it is actually there? I have been looking and looking. I read that they were going to add it to the next release of efsl, but I don't think it is released yet. Maybe you have a link to it that I cannot find? Thanks very much, Steve _____
