  1. Another trivial port... this is the RTCLib I've been using for a couple of AVR projects, it runs with really minor modifications (just stripped out PROGMEM related stuff). I've already pulled a request to the main repo (I've been contributing DS1388 to this lib in the past). While the pull gets in, here is the library on my fork: https://github.com/elpaso/rtclib I've tested the library on my LP 1.5 with a DS1388 (3.3V version) and it's working fine. Example #include <Wire.h> #include <RTClib.h> RTC_DS1388 RTC; DateTime now; // Ugly globals... uint8_t timeH; uint8_t timeM; volatile uint8_t timeS; uint8_t dateD; uint8_t dateM; uint16_t dateY; uint8_t dateW; void setup() { Wire.begin(); RTC.begin(); if (!RTC.isrunning()) { // following line sets the RTC to the date & time this sketch was compiled RTC.adjust(DateTime(__DATE__, __TIME__)); } } void loop() { // Read clock now = RTC.now(); timeH = now.hour(); timeM = now.minute(); timeS = now.second(); dateD = now.day(); dateM = now.month(); dateY = now.year(); // Do something with those figures... }

    PCF8563 - random time

    I solder on spare pcb a pcf8563 acording to diagram: PCF is connected to I2c 3 (PD_0 and PD_1). Tiva-C is flashed with code: #include <Wire.h> #include <RTClib.h> RTC_PCF8563 RTC; void setup () { Serial.begin(57600); Wire.setModule(3); Wire.begin(); RTC.begin(); // following line sets the RTC to the date & time this sketch was compiled RTC.adjust(DateTime(__DATE__, __TIME__)); } void loop () { DateTime now = RTC.now(); Serial.print(now.year(), DEC); Serial.print('/'); Serial.print(now.month(), DEC); Serial.print('/'); Serial.print(now.day(), DEC); Serial.print(' '); Serial.print(now.hour(), DEC); Serial.print(':'); Serial.print(now.minute(), DEC); Serial.print(':'); Serial.print(now.second(), DEC); Serial.println(); delay(3000); } In terminal I got: 2013/12/29 17:45:31 2013/12/29 17:45:34 2032/11/17 5:37:13 2013/12/29 17:45:40 2013/12/29 17:45:43 2052/1/17 5:46:13 2013/12/29 17:45:49 2052/11/17 5:52:13 2052/11/17 5:55:52 2052/19/17 5:58:52 2013/12/29 17:46:1 2013/12/29 17:46:4 2012/1/17 6:7:13 2013/12/29 17:46:10 2012/11/17 6:13:13 2012/11/17 6:16:12 2013/12/29 17:46:19 2013/12/29 17:46:22 2032/1/17 6:25:13 2032/9/17 6:28:32 2013/12/29 17:46:31 2013/12/29 17:46:34 2032/11/17 6:37:13 2013/12/29 17:46:40 2052/1/17 6:43:13 2013/12/29 17:46:46 What is the cause of such problems? PCF not keep proper time. The same PCB works on Arduino and the same code and libraries.

    MSP430G2*** + RTC PCF8563

    Hi guys Here I am again to ask for help :oops: So the deal is this: I'm waiting for a nokia 5110 LCD screen to arrive and I'm thinking on what I can do with it. My idea was to make something like a clock with a thermometer and, with an accelerometer, when I bounce it it works like a magic 8 ball (I think about a decision I have to make and it "helps" me with a "Yes" "No" and "Maybe" answer). The maginc 8 ball isn't a real issue. I gess that the code is pretty simple (I can use a sample code from the book "Getting started with the MSP430") and that shouldn't be a problem. My problem is about using a RTC chip to deal with the clock. Is that really needed? A MSP430G2542 is capable of doing the job (Thermometer + clock + analog accelerometer reading)? Hope anyone can help me. canibalimao
