Arduino Pgm_Read_Word. 3 you are correct in using snprintf_p to allow the format string to be read from progmem. The outer pgm_read_byte reads that memory at an offset of b.

Source code the pgm_read_word () is defined in hardware/tools/avr/avr/include/avr/pgmspace.h as below. Pgm_read_byte_near(address_short) pgm_read_word_near(address_short) pgm_read_dword_near(address_short) pgm_read_float_near(address_short) pgm_read_ptr_near(address_short) 另一种是采. // read back a char for (byte k = 0; 3 you are correct in using snprintf_p to allow the format string to be read from progmem. I want to change »string_table_xx« in »pgm_read_word (string_table_xx)« dynamically. Since you know that those 16 bits are a signed integer, you should cast them to a signed integer. Web the pgm_read_byte () is a macro that read a word of data stored in a specified address (progmem area). There will be lots of room for the 16 bit address in the 32 bit pointer. Const progmem float f = 3.12; Program space utilities // const unsigned long long_table [] progmem = {1ul, 20ul, 300ul, 5000ul, 60000ul, 700000ul};
Serial.println( pgm_read_dword( &d ) ); Web progmem pgm_read_word usage within loop. Increpare (stephen lavelle) december 2, 2016, 11:53am #2 waait i didn’t read closely enough: And you have to use the address with ' & ', like this: So i thought may be i should define menu_str [] in the following way. K++) { mychar = pgm_read_byte_near (signmessage + k). Web the pgm_read_byte () is a macro that read a word of data stored in a specified address (progmem area). Web 1 answer sorted by: Web arduino noob here, struggling to understand how a couple of things work in a sketch i'm trying to hack. To specify that the string argument is in flash memory, you must use %s in the format string, with a capital s: System january 23, 2012, 8:27pm 2.
