Hardware Peripheral Write using Address

Question asked by ATHMESH NANDAKUMAR on Dec 7, 2018

I'm working on MODBUS protocol, where I have to write to pin using address given by master. Is it possible to write to a peripheral using peripheral address?

 

IDE: MCUXpresso

Controller : LPC1517

 

Brief:

I would like to write to GPIO PIN PIO1_0, whose byte address is 0x1c000020. So, in order to make the pin high, should I write to address 0x1c000020? I tried using the following code: 

 

 uint8_t volatile *gpio = (uint8_t *)0x1c000020;
 *gpio = 0x1;

Is it possible to do so?a
