4/28/2024 0 Comments Arduino mega 2560 pin out![]() ![]() I'm not sure if I've just wired something wrong, but my guess is that it's a software problem. Since it wasn't working, I tried switching the power to the Mega's 5V connection, since I read that the lights should still work but would just be dim. To give the matrix power, I first tried connecting 3 AA batteries in series to achieve 4.5 volts. ![]() #define PIN_OTHER_SPI_nCS 1, per this thread? Arduino mega using dmd library (SOLVED) -Freetronics Forum I am maybe also supposed to change #define PIN_OTHER_SPI_nCS from 10 to 1, i.e. I'm basically adapting this guide for the Uno to the Mega: LED Display Board using P10 LED Matrix Display and Arduinoīased on several threads, I've modified the DMD.h file to change to pins 51 and 52, as I understand this has something to do with the Mega using different pins for the SPI feature: I wanted to use them as interrupt PINs either connected to 5V or with an 10k pulldown resistor to ground, but even with the pulldown the voltage doesnt really drop (just from 3.11 V to 3.09 V). Purchased a P10 32x16 PMD to use with my Mega but can't seem to get the software or hardware figured out, not sure which. Hej there, I have the problem that on my Arduino Mega 2560 PINs 18-21 are always high, with these values 18 (3V), 19 (5V), 20 (3V), 21 (3V). This is how I connected my Nextion Display to the Arduino Mega. But whatever I try, I cant seem to get values from the arduino code to show on the Nextion Display. Just throwing this out there in case I get lucky. Hello all, Im trying to get my Nextion Display to work with my Arduino Mega2560.
