LPCOPEN and PINCON

agustinbanchio — Mon, 05 Jun 2017 20:25:04 GMT

I have an LPC1769 and been using LPCXpresso with cmsis and got used to using LPC_PINCON for (PINSEL and PINMODE) and LPC_GPIO0 and LPC_GPIO2 for port 0 and port 2 Fast input output. I need USB for a project I'm working on and the LPCOpen example works, but it doesn't have PINCON and GPIO functions that I had with CMSIS 1v30. If I try mixing the include statements many things get declared twice and there are lots of error while compiling. Is there a way to add this device specific functions to LPCOpen examples?

Hi,

You can use the Chip_GPIO_SetPinState function, for example:

void Board_LED_Set(uint8_t LEDNumber, bool On)
{
   if (LEDNumber == 0) {
       Chip_GPIO_SetPinState(LPC_GPIO_PORT, 1, 12, (bool) !On);
   }
   else if (LEDNumber == 1) {
       Chip_GPIO_SetPinState(LPC_GPIO_PORT, 1, 11, (bool) !On);
   }
}

Please check the following document:

Have a great day,

Thank you sole, I'll be reading about this functions, they seem pretty straight forward. Again thanks a lot.
