Timer0: Timer0 is a 8bit timer. In the Arduino world Timer0 is been used for the timer functions, like delay(), millis() and micros(). If you change Timer0 registers, this may influence the Arduino timer function. So you should know what you are doing. Timer1: Timer1 is a 16bit...
there are other problems that can cause your code to crash and Arduino to lock up. Timeouts on peripherals, power issues, RFI, etc., etc. Bad code using the millis() function is a classic problem. You need to handle the rollover at 49.5 days ...
We will be using the Wio Terminal’s built in button inputs to control the timer. If you are using another Arduino board, you will require a minimum of two additional buttons to take advantage of the full program functionality. You will also have to reconfigure the input pins in the setu...
Any ISP programmer that can program ATtiny is ok, I am using USBasp this time. Step 3: Software Preparation Arduino IDE Download and Install Arduino IDE latest 1.x version if not yet: https://www.arduino.cc/en/Main/Software SpenceKonde/ATTinyCore ...
I am using a time critial library (MCCI LMIC), that depends onmicros()as monotonic time base. In arduino-esp32micros()is hardwired toesp_timer_get_time(), which does not persist it's counter value during deep sleep. Thusmicros()cannot act as a monotonic counter after waking up from ...
void initSystems(void *param) { esp_task_wdt_add(NULL); // SPIFFS unsigned long now = millis(); while (!SPIFFS.begin(true)) { while (millis() - now < 100u); } esp_task_wdt_reset(); now = millis(); while (!Wire.begin()) { debug("Failed to start Wire"); while (millis(...
The possible exceptions it throws areIllegalArgumentExceptionif the delay is negative, ordelay + System.currentTimeMillis()is negative. TheIllegalStateException, if the task was already scheduled or canceled, the timer was canceled, or timer thread terminated,NullPointerExceptionif the task is null....

Then run the following command using sudo$ cd ~/.arduino15/packages/arduino/hardware/mbed_portenta/3.4.1 $ chmod 755 portenta_post_install.sh $ sudo ./portenta_post_install.sh This will create the file /etc/udev/rules.d/49-portenta_h7.rules as follows:...
