Hi
I bought NHS3152DBUL and LPC_LINK2, I debugged nhs31xx SDK(release_mra2_12_1_nhs3152)
app_demo_dp_blinky project to NHS3152 using LPCXpresso IDE after connecting NHS3152 and LPC_LINK2.
(Before debugging, I imported all projects and libraries in the SDK folder and set MCU setting -> NHS3152)
Below is mainblinky.c code.
#include "board.h"
int main(void)
{
Board_Init();
/* Optional feature: send the ARM clock to PIO0_1 */
Chip_IOCON_SetPinConfig(NSS_IOCON, IOCON_PIO0_1, IOCON_FUNC_1);
Chip_Clock_Clkout_SetClockSource(CLOCK_CLKOUTSOURCE_SYSTEM);
/* Blink with a period of 250ms+250ms, or 2Hz */
while (1) {
LED_Toggle(LED_RED);
Chip_Clock_System_BusyWait_ms(250);
}
return 0;
}
Debugging itself is well done.
I checked blinking by connecting LED to GND and each port.
According to this code, LED connected to PIO0_1 should blink in 2Hz, but LED connected to PIO0_7 is the one blinking not PIO0_1.
I also tried to change code from PIO0_1 to PIO0_0,2,6 but all these case, PIO0_7 is the only one blinking.
ex) Chip_IOCON_SetPinConfig(NSS_IOCON, IOCON_PIO0_2, IOCON_FUNC_1); // change port to PIO0_2
and I tried to DAC using ANA0_0,1,2 port from example 1(in firmware example)
I modified c file mainblinky.c in app_demo_dp_blinky project.
#include "board.h"
int main(void)
{
Board_Init();
/* Optional feature: send the ARM clock to PIO0_1 */
Chip_IOCON_SetPinConfig(NSS_IOCON, IOCON_ANA0_0, IOCON_FUNC_1);
Chip_ADCDAC_Init(NSS_ADCDAC0);
Chip_ADCDAC_SetMuxDAC(NSS_ADCDAC0, ADCDAC_IO_ANA0_0);
Chip_ADCDAC_SetModeDAC(NSS_ADCDAC0, ADCDAC_CONTINUOUS);
Chip_ADCDAC_WriteOutputDAC(NSS_ADCDAC0, 3000);
while(1){}
return 0;
}
I also tried to change ADCDAC_CONTINUOUS to ADCDAC_SINGLE_SHOT but even two cases are not working(voltage between Analog port and GND is always zero. LED is also not working)
app_demo_dp_tlogger is working well. if I debuged this project and taged my nhs3152 board to smartphone, temperature is read well.
I couldn't find situation like me in the NXP community. TT
So I want to know,
1. why digital port PIO0_7 is working only??
2. How to make code to control digital port and analog port?? I want to set PIO0_1 in high state(3.3V) and set ANA0_1 to 1V.
If possible, I want to get example whole code(c file like mainblinky.c) or project.
1. why digital port PIO0_7 is working only??
- Because the project set PIO0_7 as the LED_RED, so you have to modify somewhere else. Please refer to the following for details.
2. How to make code to control digital port and analog port?? I want to set PIO0_1 in high state(3.3V) and set ANA0_1 to 1V.
-Actually I copied your code and tested it on my side, the result is 1.3126V on AN0, please refer to the following for details.
Is there any difference from your settings?
Have a great day,
Kan
