Arduino Core for the ATMEGA4809 CPU
In trying to solve some I2C issues I've been having, I came across [this](https://github.com/arduino/ArduinoCore-avr/pull/107) thread (and a great many others), which indicate the Wire libraries don't have any timeout capabilities,...
Hello, i have loaded successfully last version, i have replaced CRC table with calculation. I have encountered errors on UART reception. 115200baud speed. Transmittion from atsam->atmega works great(perfect timing and...
Hello, I have previously added this issue to https://github.com/arduino/Arduino/issues/11845 but perhaps it is better suited here: We have noticed a strange issue with the Arduino Nano Every. We are currently...
Hi, I get this warning when I upload code to my Arduino Wifi Rev2. Any ideas what it means? Thanks! avrdude: WARNING: invalid value for unused bits in fuse "fuse5",...
I can not get the nano every reset by sending the 1200 baud signal and I am thinking this might because of the atsamd11d14a is not doing that. I noticed...
Currently MegaAVR is one of the very few platforms where digitalWrite doesn't take a boolean for `digitalWrite` (there's no `digitalWrite(uint8_t pin, bool val)`), this causes unnecessary incompatibility with a massive...
Hi, i'm trying to establish an MASTER/SLAVE Communication between 2 Arduinos. The current idea for testing is that i want the NANO to generate random numbers and send it back...
The datasheet/pinout for the Nano Every shows A4/A5 as PA2/PA3, but from my reading of the ATMega4809 datasheet, these are not the I2C port that will also support the ADC....
For the Nano Every, NUM_ANALOG_INPUTS is set to 14, presumably to allow for AIN12 and AIN13 to be used for A4 and A5. For the Wifi Ref 2 NUM_ANALOG_INPUTS is...
The default 100 kHz works, and the `Wire.setClock(100000L)` works. If the clock is set to 800 kHz or above, then the SCL signal stays low because of a missing stop...
