updateRAM16()

[RAM]

void updateRAM16(unsigned short address, unsigned short value);

Description

Updates the RAM memory with the specified short value at the specified address.

Parameters

address: the address where the data will be written.

value: the data to be written if the data is different from the data already stored in the RAM memory.

Returns

Nothing.

Example Code

The code initializes the RAM with a size of 1024 and a width of 2 bytes and updates the value in the RAM memory at the address 0x00 with a counter value, incrementing it by one each time the loop is executed.

void setup() {
    beginRAM(1024, 2);          // initializes the RAM memory with a size of 1024 * 2 bytes
    writeRAM16(0x00, 0x0000);   // writes the value 0x0000 to the RAM memory at the address 0x00
}

void loop() {
    unsigned short value = readRAM16(0x00);  // reads the value from the RAM memory at the address 0x00
    value++;                                   // increments the value by one
    updateRAM16(0x00, value);               // updates the value in the RAM memory at the address 0x00
}

Notes and Warnings

• The updateRAM16() function can only be used after the beginRAM() function.
• The value parameter must be a 16-bit value (0-65535) or an unsigned short.
• If the programmer initializes the RAM with a width lower than 2 bytes, the function will write only 8 bits of the data.
