64 bit integer numbers (long long/signed long long/unsigned long long/int64_t/uint64_t) along with the ULL formatter are currently not documented although the U/L/UL formatters have been documented in "Integer Constants". Can...
I got bitten by this delay in a loop that otherwise would easily keep up with interrupts. I think users should be aware of it! One would not expect such...
Migrated from https://github.com/arduino/Arduino/issues/6247 I'm going to leave off the text of the original issue because it was written under the misunderstanding that this is a feature specific to `Serial.print()`. However,...
Hello Could you bring back this link in the Reference or Librairies page ? Regards
Using pins 20, 21 for interrupts on the MEGA 2560 can cause some real headaches if not aware that they have external pull up resistors on them. The pull ups...
`serialEvent()` support across the official Arduino boards is quite patchy. Previously, the support accross these boards was not completely (or correctly in the case of the Due) documented. Screenshot of...
There is no actual reason to put a method that counts characters inside a `for-loop`, such that every iteration will reevaluate the length of `signMessage`.
Hopefully this small addition will help uses avoid a common pitfall with mechanical chatter.
The 1.65V and 2.23V are not generated from a build in reference. They are only calculated by the devider 1/2 and 1/1.48 from the system Voltage. People who want to...
After working with the Arduino Nano 33 BLE, I discovered that calling `analogWrite` on more than 4 pins will lock up the board. This is confirmed by https://forum.arduino.cc/t/arduino-nano-33-ble-damaged/639669/2. I think...
