Arduino Pgm_Read_Word. Serial.println( pgm_read_float( &f ) ); I have a requirement to store two dimensional arrays of numbers in progmem.

X = pgm_read_byte (framepos++) i read this as: Web the pgm_read_word_near () returns an unsigned integer. Const progmem float f = 3.12; Serial.println( pgm_read_float( &f ) ); Program space utilities // const unsigned long long_table [] progmem = {1ul, 20ul, 300ul, 5000ul, 60000ul, 700000ul}; (unless you want the word from address 85 of ram.) and pointer is already a pointer, so you don't need the & in front of it. Web 1 answer sorted by: Web the arduino docs on progmem sometimes use pgm_read_word and sometimes use pgm_read_word_near? Web pgm_read_byte_near(address) − this function returns the value of one byte located at address. The address is in the program space.
3 you are correct in using snprintf_p to allow the format string to be read from progmem. 3 you are correct in using snprintf_p to allow the format string to be read from progmem. K++) { mychar = pgm_read_byte_near (signmessage + k). There is no pgm_read_int_near (). Serial.println( pgm_read_dword( &d ) ); And you have to use the address with ' & ', like this: The outer pgm_read_byte reads that memory at an offset of b. Const progmem double d = 3.12; The address is a byte address. Web that makes me think there is something wrong with the way i am using pgm_read_word().
