Hello, I'm trying to configure I2C functinoality on PIO04 and PIO05 on a LPC1114. The same code works on CooCox but it won't work with Keil. I found that in Keil the register LPC_IOCON->PIO0_4 and LPC_IOCON->PIO0_5 aren't changing. The code I used is the following:
// variables volatile uint32_t IOCONP04 = 0, IOCONP05 = 0;
// manage to change the register LPC_SYSCON->PRESETCTRL |= (0x1<<1); LPC_SYSCON->SYSAHBCLKCTRL |= (1<<5); LPC_IOCON->PIO0_4 &= ~0x3F; /* I2C I/O config */ LPC_IOCON->PIO0_4 |= 0x01; /* I2C SCL */ LPC_IOCON->PIO0_5 &= ~0x3F; LPC_IOCON->PIO0_5 |= 0x01; /* I2C SDA */
// checking if changes were done IOCONP04 = LPC_IOCON->PIO0_4; IOCONP05 = LPC_IOCON->PIO0_5;
After this, in the watch window, I see 0x0000 for both registers. In CooCox this value is 0d193 for both.
Please help! I depend on this to change IDE from CooCox to Keil!
