| Feb 1, 2018 at 20:24 | comment | added | Juraj♦ | nothing about A4 and A5 in wiki. Yes, D11, D12 and D13 are SPI connected to D labeled pins and to ICSP header. | |
| Feb 1, 2018 at 20:17 | comment | added | Majid Hojati | @Juraj I noticed that the shield uses ICSP pins but It also uses A4 and A5 In its wiki it says:D11, D12 and D13 are the MISO, MOSI and SCLK buses of the SPI interface by default. | |
| Feb 1, 2018 at 19:12 | comment | added | Juraj♦ | if you have the usual stackable shield headers on the shield, the you can connect to pins not used by the shield | |
| Feb 1, 2018 at 19:07 | comment | added | Juraj♦ | all pins will be the same if the shield uses the ICSP header for SPI comunication | |
| Feb 1, 2018 at 10:36 | comment | added | Juraj♦ | the SPI pins should the shield connected over the ICSP header. it is on the same place on Uno and Mega. the helper pins are then connect to other gpio pin numbers on Mega. | |
| Feb 1, 2018 at 10:25 | comment | added | Majid Hojati | @Juraj actually I am thinking about using only MEGA, But I have no idea about changing pin mapping | |
| Feb 1, 2018 at 10:25 | comment | added | Majid Hojati | @Juraj but it fills all pins when I put it on Arduino, | |
| Jan 31, 2018 at 17:03 | comment | added | Juraj♦ | and perhaps it can be used on Mega with changed pin mapping | |
| Jan 31, 2018 at 16:58 | comment | added | Juraj♦ | the MP3 shield you linked doesn't use A4 and A5 | |
