![]() All weekend I was on this and still not resolved. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. The Mega 2560 has 54 digital pins, whereas. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. They do not map to the left side pwr bus with RESET, 3.3V, 5V, GND, GND. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. I have done the Pin mapping below following the board branch shown here ’s%20manual.pdf:īut I still have the same error. Im referring to the 2 PWR/GND labeled on the ends of the digital bus/port and the GND pin just above P13 on the Arduino Mega 2560. pin number 1 on the 2560 micro can be used as a general purpose IO (pin 4 on the Mega board) or as a PWM output on the same pin 4. The Ramps itself has no logic, nothing to interpret the signals coming from the Pi. Now it no longer puts \LMIC-Arduino\src\lmic\radio.c:689 but rather \MCCI_LoRaWAN_LMIC_library\src\lmic\oslmic.c:53. The Ramps is more or less an adapter board that maps the arduino pins to the drivers (and a few other peripherals). The table was built for OpenPLC v2, but it is still valid for OpenPLC v3, except that the slave address on v3 starts at position 100 (e.g. Sorry, that’s when I had the old version of LMIC. Below you can find the pin mapping for Arduino Uno and Arduino Mega boards. Or an Uno, which won’t have the space to run the LMIC but you can at least run the diagnostic library. If another SPI device won’t work, then I’d suspect the Mega or the other device. It that’s not able to talk to the radio I’d unplug the shield, try another SPI device to test that on the Mega and if that works, use jumper cables to link the shield to the Arduino. This opens the pin mapping table for Arduino boards and Arduino compatible ESP32 boards. The thing to try after checking the pin matching when you plug it in if that doesn’t make it work is to scroll up this thread to the very top and use library to run some diagnostics. To view the pin mapping for these blocks, click View pin map in the Block Parameters dialog box. The Arduino has an issue of some sort, it it’s broken The mapping of pins of the ATmega 2560 chip is in the datasheet.The shield has an issue of some sort, ie it’s broken. ![]() ![]() The shield is not plugged in quite right for the Mega - check that the pin numbers on the shield align with the pins on the Mega.Hmmmm, I wonder how you ended up with the older (deprecated) repro’s radio.c which you quoted above as it is the only one that has the assert on line 689.Īs this thread is getting rather protracted, the short version of your problem is that the code is requesting the version of the radio chip and not getting back the result it expects. ![]()
