MSP Launchpad Exp430G2 with Exp430G2553 Rev 1.5 Energia 1.6.10E18 MacOS Sierra 10.12.6 Hello friends, When I call attachInterrupt at the end of a service Routine after I detached it from a pin, I find that it takes a long time for that call to finish (two seconds). Do you have any hint how I can make that faster? Thanks

MSP Launchpad Exp430G2 with Exp430G2553 Rev 1.5 Energia 1.6.10E18 MacOS Sierra 10.12.6 Hello friends, Is it possible to use the functions "attachInterrupt" or "Interrupts" inside an Interrupt Service Routine? For me, it doesn't seem to work. I made a little example: I have to pins with momentary switches attached to them. One is externally configured with a PullUp-Resistor, and the other is externally configured with a PullDown-Resistor. Both switches should be attached to another ISR. But I need to turn off the ISR that is not used, if one ISR is entered, b

Hello! I recently started playing with Energia and the CC3200 LaunchPad. I tried the example for "attachInterrupt" in the link: http://energia.nu/reference/attachinterrupt/ I changed the code a little by modifying pinMode and attachIntterrupt #define PUSH 4 ... pinMode(PUSH, INPUT); // I want Pin 4 as my interrupt or SW3 on the board, only Input because the board has a pull down resistor already attachInterrupt(PUSH, blink, FALLING); } void loop() { ... } When I run this example, the interrupt is serviced multiple times at random without me touching the button. I

Hey there, there is an error on the site in the example of attachInterrupt function. the page: http://energia.nu/AttachInterrupt.html Tested the code on my MSP430G2 Launchpad. The correct code should be: volatile int state = HIGH; volatile int flag = HIGH; int count = 0; void setup() { Serial.begin(9600); pinMode(GREEN_LED, OUTPUT); digitalWrite(GREEN_LED, state); pinMode(PUSH2, INPUT_PULLUP); //The correction attachInterrupt(PUSH2, blink, FALLING); // Interrupt is fired whenever button is pressed } void loop() { digitalWrite(GREEN_LED, state); //LED starts ON
