HI,
Recently I am using LPC43S67 & A70CM Cloud Connectivity Kit (OM13086),
although I am using the main board OM13084.
I have a problem that SSEL pin on Pmod (J3) connector is not controllable.
I try to control it as a GPIO pin.
I connect a LED between the SSEL pin and the GND pin of J3 connector.
And no matter I set the GPIO state of that pin to true or false, the LED is not on.
Similar code works on another GPIO pin, P1.5.
Do I miss something?
The following is my code:
#if defined (__USE_LPCOPEN)
#if defined(NO_BOARD_LIB)
#include "chip.h"
#else
#include "board.h"
#endif
#endif
#include <cr_section_macros.h>
int main(void) {
#if defined (__USE_LPCOPEN)
// Read clock settings and update SystemCoreClock variable
SystemCoreClockUpdate();
#if !defined(NO_BOARD_LIB)
#if defined (__MULTICORE_MASTER) || defined (__MULTICORE_NONE)
// Set up and initialize all required blocks and
// functions related to the board hardware
Board_Init();
#endif
// Set the LED to the state of "On"
Board_LED_Set(0, true);
#endif
#endif
// TODO: insert code here
#if 1
Chip_SCU_PinMuxSet(0x3, 8, (SCU_MODE_INACT | SCU_MODE_FUNC4)); /* P3.8 => GPIO5[11] */
Chip_GPIO_SetPinDIROutput(LPC_GPIO_PORT, 5, 11);
Chip_GPIO_SetPinState(LPC_GPIO_PORT, 5, 11, (bool) true);
// Chip_GPIO_SetPinState(LPC_GPIO_PORT, 5, 11, (bool) false);
// Chip_GPIO_SetPinOutHigh(LPC_GPIO_PORT, 5, 11);
// Chip_GPIO_SetPinOutLow(LPC_GPIO_PORT, 5, 11);
#else
Chip_SCU_PinMuxSet(0x3, 6, (SCU_MODE_INACT | SCU_MODE_FUNC0)); /* P3.6 => GPIO0[6] */
Chip_GPIO_SetPinDIROutput(LPC_GPIO_PORT, 0, 6);
Chip_GPIO_SetPinState(LPC_GPIO_PORT, 0, 6, (bool) true);
#endif
// Force the counter to be placed into memory
volatile static int i = 0 ;
// Enter an infinite loop, just incrementing a counter
while(1) {
i++ ;
}
return 0 ;
}
Thanks for any help.
Frank
