Arduino Pgm_Read_Word. Web the progmem keyword is a variable modifier, it tells the compiler to keep this variable in flash memory, instead of loading it into sram. Unsigned int totalmenuitems = pgm_read_word(&data.totalmanufacturers);

Web needed for native usb // put your setup code here, to run once: 3 you are correct in using snprintf_p to allow the format string to be read from progmem. Web that makes me think there is something wrong with the way i am using pgm_read_word(). This solution can also be broken down into two parts: Web progmem pgm_read_word usage within loop. Web arduino noob here, struggling to understand how a couple of things work in a sketch i'm trying to hack. Web 1 answer sorted by: The value is an address. Const progmem float f = 3.12; Const progmem double d = 3.12;
The usage of these functions will be clear in the example below. So i thought may be i should define menu_str [] in the following way. In order to use these functions, the target device must support either the lpm or elpm instructions. Web the progmem keyword is a variable modifier, it tells the compiler to keep this variable in flash memory, instead of loading it into sram. So that should just be: Web that makes me think there is something wrong with the way i am using pgm_read_word(). K++) { mychar = pgm_read_byte_near (signmessage + k). Source code the pgm_read_word () is defined in hardware/tools/avr/avr/include/avr/pgmspace.h as below. Web 1 answer sorted by: Unsigned int totalmenuitems = pgm_read_word(&data.totalmanufacturers); String_table_01 and string_table_02 are names.
