Arduino Code for test Heart Rate 7 Click

Heart Rate 7 Click is the newest module from MikroE which uses VEM8080 photodetector has a wide range spectrum from 300nm - 1000nm. To control and acquisition data, AFE4404 from TI inc. is adopted. This chip permits control 3 LED channels, and sample heart rate default 100 SPS.  A 22-bit ADC permit collecting very small changed voltage from a PD sensor. In this example we config Arduino Mega  2650 as below: Pin 4 for RST PIN 5 CLK PIN 6 INT PIN 20 SDA PIN 21 SCL Config registers follow the default of AFE4404 datasheet Page 27 with some minor changes. 1. Config Internal Clock through  AFE_CONTROL2 register addr.: 0x23 value: 0x104218  // setup all dynamic power to save energy 2. Control LED2 current through AFE_LEDCNTRL register addr: 0x22 value: 0x000100 3. Read data using PROG_TG_EN signal through AFE_TIA_GAIN register addr: 0x21 value: 0x000125 Time to start and end of PROG_TG setup through two registers: AFE_PROG_TG_STC register (...

Programing on Launchpad MSP432 Interrupt button Prerequisite: Hardware: Launchpad MSP432P401 IDE software: IAR/CCS/KEIL Tool: Simplelink SDK MSP432 v3.20.00.06 Description: Simple program using two buttons connected to P1.0  and P1.4 to turn on or turn off LED on P1.0 Step1. Open example of Simplelink SDK without RTOS Step2. modify the code as below Step3. Compile and debug the program /* DriverLib Includes */ #include <ti/devices/msp432p4xx/driverlib/driverlib.h> /* Standard Includes */ #include <stdint.h> #include <stdbool.h> volatile uint32_t SW1, SW2; //semaphores void VectorButtons_Init(void){   __disable_interrupt;   //DisableInterrupts();          // set the I bit during initialization   SW1 = 0; SW2 = 0;             // clear semaphores   P1->SEL0 &= ~0x12;   P1->SEL1 &= ~0x12;      P1->D...
