Hello Sir,
I am using LPC2368 controller in my project My project have some 1-bit flag as shown in following code flag number 1 to 22 working properly means writing 0 or 1 has affect on that. But when I write 1 value to flag there is no change in flag.when i declare flag number ,23 ,24 ,25 of 1 byte seperately instead of using in this structure they are working properly i just want to confirm that is there is any bit addressable area in LPC2368 I checked the memory map of my project i sae that genflag structure is stored at 0x40000128 address and it is taking 12 byte why it is taking 12 byte?
struct flag{ unsigned fill_start:1; //1 unsigned pow_pap_feed:1; //2 unsigned fl_print_start:1; unsigned fl_stop_print:1; unsigned fl_pap_sensor:1; unsigned fl_platen_out:1; unsigned fl_cutr_acc_ON:1; unsigned fl_const_speed:1; unsigned fl_line_print:1; unsigned fl_start_print:1; unsigned fl_pf_only:1; unsigned fl_start:1; unsigned fl_mt_accer:1; unsigned fl_mt_deaccer:1; unsigned fl_phase_rev:1; unsigned fl_half_cut:1; unsigned fl_home_position; unsigned paperout:2; unsigned fl_tempabove_80:1; unsigned fl_recive_enable:1; unsigned fl_init:1; unsigned fl_stop_receive:1; //22 unsigned fl_ESC_command:1;//23 unsigned fl_GS_command:1;//24 unsigned receive_cmd_arg:1;//25 unsigned wait4chartimeout:1;//26 }genflag;
Thanks & Regards Rohit
