  1. MSP432 RTC User adjust

    now I have done some alterations on my file clock.c, and i see in the register's the clock working, so how can I get each parameter (Year, Month, Day, Hour, Minute)
  2. MSP432 RTC User adjust

    can anyone some help me? I have some problems with user rtc configuration in msp432 I made a firmware where the user choose by hardware configuration adjust date and time (alarm clock). The problem is ... after the user adjust date and time I would like use the rtc to control the watch and show the current date and time in a lcd. The problem is ... after the user adjust date and time I would like use the rtc to control the watch and show the current date and time in a lcd. Soo i need some help in two things pass the user value (decimal) to hexadecimal or BCD and the inverse get the hexadecimal or BCD value to decimal to show in LCD . I'am using CCS, in CMSIS on attach i leave the code I have made to test it! test.zip

  4. Fellows, I'am trying to adquire a signal with ADC converter in the MSP432, but some problems appeard. I try to read lm35 sensor temperature and before conect the lm35 output signal to input pin of MSP432, i made a mesurement with multimeter and i see the pin has 1.10 +/- 1.15v. It's this normal? The code was made in ccs, and with classic programation (registers), this is the code: #include "adc.h" #include "lcd.h" #include "stdio.h" extern char Mensaje[]; /**/ void adc(void){ volatile unsigned int i; /*ADC CONFIGURATION*/ P5->SEL1 |= BIT4; P5->SEL0 |= BIT4; /*ENABLE GLOBAL INTERRUPTS*/ __enable_irq(); /*ENABLE ADC INTERRUPT IN NVIC MODULE*/ NVIC->ISER[0] = 1 << ((ADC14_IRQn) & 31); /*Sampling time, S&H=16, ADC14 on*/ ADC14->CTL0 = ADC14_CTL0_SHT0_2 | ADC14_CTL0_SHP | ADC14_CTL0_ON; ADC14->CTL1 = ADC14_CTL1_RES_2; ADC14->MCTL[0] |= ADC14_MCTLN_INCH_1; ADC14->IER0 |= ADC14_IER0_IE0; SCB->SCR &= ~SCB_SCR_SLEEPONEXIT_Msk; while (1) { for (i = 20000; i > 0; i--); // Start sampling/conversion ADC14->CTL0 |= ADC14_CTL0_ENC | ADC14_CTL0_SC; __sleep(); __no_operation(); } } void ADC14_IRQHandler(void) { int value_adc=ADC14->MEM[0]; float value_vol= value_adc * (3.3/4096); //sprintf(Mensaje,"%d",value_adc); sprintf(Mensaje,"%1.2f",value_vol); LCD_SetText(Mensaje,5 ,0); }

  9. Hello Friends, Now I facing some problems with getting correct readings of ADC ports in MSP432. I Am using a multimeter to get the viability of the correct process. I am using CCS 7.0 and CMSIS mode writing code. My question... it's normal the measurements not be stable? I am using P5.5 pin port (A0) and this pin have different values of voltage, or any time change the value. It' is normal? I leave my code for get the readings for the ADC. #include "msp.h" /*DEFINE VAR LIKE A INTEGER*/ volatile int value_adc; void ADC_Initialize(void){ /*CONFIGURE LED OUTPUT*/ P1->OUT &= ~BIT0; /*CLEAR LEAD OUTPUT */ P1->DIR |= BIT0; /*SET DIRECTION OUTPUT*/ /*ADC CONFIGURATION*/ P5->SEL1 &= ~BIT5; /*CONFIGURE P5.5 (A0) FOR ADC*/ P5->SEL0 |= BIT5; /*ENABLE GLOBAL INTERRUPTS*/ __enable_irq(); NVIC->ISER[0] = 1 << ((ADC14_IRQn) & 31); /*ENABLE ADC INTERRUPT IN NVIC MODULE*/ ADC14->CTL0 &= ~ADC14_CTL0_ENC; /*CONFIGURE ADC14*/ ADC14->CTL0 = ADC14_CTL0_SHT0_2 | ADC14_CTL0_SHP | ADC14_CTL0_ON; /*ADC14 ON | S&H=16 | SAMPLING TIME*/ ADC14->CTL1 = ADC14_CTL1_RES_3; /*USE SAMPLE TIME, 14 BIT'S CONVERSION RESULTS*/ ADC14->MCTL[0] |= ADC14_MCTLN_INCH_0; /*A0 ADC INPUT SELECT Vref=AVCC*/ ADC14->IER0 |= ADC14_IER0_IE0; /*ENABLE ADC CONVERT COMPLETE INTERRUPT*/ SCB->SCR &= ~SCB_SCR_SLEEPONEXIT_Msk; } void ADC_Task(void){ volatile unsigned int i; //P1->OUT ^= BIT0; for (i = 200000; i > 0; i--); /*DELAY CYCLE*/ ADC14->CTL0 |= ADC14_CTL0_ENC | ADC14_CTL0_SC; /*ENABLE CONVERTION | SAMPLING CONVERSION*/ __sleep(); __no_operation(); } void ADC14_IRQHandler(void) { // if(ADC14->MEM[0] >= 0x7FF){ /*CONVERT DE SIGN OF CONVERTION IN A VARIABLE*/ value_adc = ADC14->MEM[0]; LCD_SetInt(value_adc,12 ,0); printf(value_adc); /*VERIFY IF THE INPUT PINS IS SET TO*/ //while(ADC14->CTL0 & ADC14_CTL0_BUSY); /*VOLTAGE CALCULATIONS*/ //value_vol = (value_adc * Vref_1)/digitalValue_1; // sprintf(adcData,"%2.2f",value_vol); // LCD_SetText(adcData,6 ,0); // temp = value_vol/gradeTemp; // sprintf(TEMP_C,"%2.2f",temp); // LCD_SetText(TEMP_C,0 ,0); //LCD_SetText(TEMP_C,0 ,0); /*CURRENT*/ // UART_Task(adcData,TEMP_C); /* if(value_adc > newValue_Adc){ P1->OUT |= BIT0; }else{ P1->OUT &= ~BIT0; }*/ //}else{ // LCD_SetText("ERROR",6 ,0); //} }
  10. Hello people, I'am trying use a SDCARD only to regist data. All my project was made with "MSPClassic Registers", so I saw in the forum a Bluehash post, but was in CMSIS, in mode to satisfy my project I try to change some files.

  13. Hello fellows, I need some help, with a situation, I want convert some analog signals to digital and send him by the UART communication, but I dont get how to solve this problem. my digital values is represented by "tempADC" variable, soo how can I get a buffer with values to the pc with UART communication.

  14. How to send converted values by UART to PC

    Thank you Nurse bob, I' solved this problem, but thanks for your help.
  15. Hello I have some problems with a UART comunication to pc, I use CCS to program my code and to debug the results I use Terminal. So my code works fine and do everything well, the biggest problem is the features dont appear well in Terminal window.

  16. Enl, thank you for your answer So I understand your explanation, but how can I proced to read temperature with that sensor. Since I dont obtain a consistent temperature I remove the pin P5.4 from MSP432 and measure the output pin voltage, where I see a float voltage between 1.10 to 1.15 volts. Thank's in advance
  17. No, I don't have another device. But forget the LM35 sensor, you configure the P5.4 to receive a analog signal and convert him, why this pin have oscillation voltage, I have used a multimeter and I measure this pin and I get between 1.10 and 1.15V.
  18. Thank you Nurse Bob, for answer my question, I have 5V power supply to LM35. but my problem has in P5.4 without connect to the output pin of LM35, in the multimeter I measure 1.10 to 1.15V , why? All that calcules are in LM35 data sheet.
  19. Hello fellows, I made a code to interact the MSP430, with the LCD, but now I would like to have it interact with the MSP432. And I'm having some problems because I want to use specific pins, can anyone help me change the code? My difficulty is: the MSP430 I use PORT P1 and P2, the problem is in the MSP432 I need PORT P2, P5 and P6 This is my connections LCD->MSP432: EN -> (P2 + BIT3) RS -> (P6 + BIT7) D4 -> (P2 + BIT6) D5 -> (P2 + BIT4) D6 -> (P5 + BIT6) D7 ->(P6 + BIT6) lcd.c lcd.h main.c main.h
