This is the MCU module i'm using: (not the PR9000)

PR9200 is a true single SOC solution for UHF RFID reader which integrates high performance UHF RF with internal PA, baseband MODEM, ARM Cortex-M0 Processor, memory(64KB FLASH & 16KB SRAM)

Internal high efficiency PA Power consumption : 170mA @ +20dBm 32bit low-power high performance ARM Cortex M0 64kB embedded flash memory 16kB on-chip SRAM

I'll post the code i'm trying to compile.

Hi Richard you can use the mbed lpc11u24, it has an cortex m0 microcontroller

you can check it here:

Greetings

Thanks! ..... but this mcu has only 8KB RAM, 32KB FLASH ..... the code i'm using was based on using a 64K Flash and 16K SRAM. When I use the lpc11u24 platform, many of the SFR statements come up in error (no room?). Please advise.

Thank-you!

The KL25 has 128k flash and 16k RAM, so that should meet your demands. But I do not know if what you want to do is microcontroller specific.

Rem: I'm day one with this stuff : )

Changing to the KL25..... I get same errors:

Warning: Unrecognized #pragma in "core.c", Line: 13, Col: 8 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 15, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 16, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 17, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 18, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 19, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 20, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 21, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 22, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 27, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 28, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 29, Col: 1 Error: Identifier "sfr" is undefined in "phycore10.h", Line: 30, Col: 1

Is this an issue with using "#pragma large" ?

Hello Richard,

what code are you compiling? Share or point to the phycore10.h file. Google returned only this reference http://data.eefocus.com/myspace/0/758/bbs/2010-11-23/1290520059_411c3a56.pdf. Is your target from phychips ??

Provide please more details, the first post is not sufficient as you can see, already received 3 answers.
