I don't see this change as needed, use 'offsetof' in stddef.h: Here is a snippet of my code that I use to display all of the NVM_PROD_SIGNATURES on one of my screens: /* XMega serial number: */ (void) SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, LOTNUM0 ) ); /* First read after reset or possibly Power Up returns zero, so read then toss this value */ hex_out_buffer( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, LOTNUM0 ) ) ); hex_out_buffer( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, LOTNUM1 ) ) ); hex_out_buffer( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, LOTNUM2 ) ) ); hex_out_buffer( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, LOTNUM3 ) ) ); hex_out_buffer( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, LOTNUM4 ) ) ); hex_out_buffer( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, LOTNUM5 ) ) ); hex_out_buffer( (uint8_t) ' ' ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, WAFNUM ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, COORDX0 ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, COORDX1 ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, COORDY0 ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, COORDY1 ) ) ); hex_out_buffer( (uint8_t) ' ' ); lcd_text(SCRN_LEFT, SCRN_TOP+13, FONT_FIVE_DOT, (char *) hex_buffer_u8); hex_buf_ptr_u8 = hex_buffer_u8; /* Analog Calibrations: */ hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, TEMPSENSE0 ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, TEMPSENSE1 ) ) ); hex_out_buffer( (uint8_t) ' ' ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, ADCACAL0 ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, ADCACAL1 ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, ADCBCAL0 ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, ADCBCAL1 ) ) ); hex_out_buffer( (uint8_t) ' ' ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, DACAOFFCAL ) ) ); #if( __GCC_VERSION__ < 433 ) /* Version prior to 4.3.3 had the name wrote (C vs G): */ hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, DACACAINCAL ) ) ); #else hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, DACAGAINCAL ) ) ); #endif hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, DACBOFFCAL ) ) ); hex8( SP_ReadCalibrationByte( offsetof( NVM_PROD_SIGNATURES_t, DACBGAINCAL ) ) ); lcd_text(SCRN_LEFT, SCRN_TOP+19, FONT_FIVE_DOT, (char *) hex_buffer_u8); _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-libc-dev
