@@ -8,6 +8,25 @@ i believe it is possible to read midi in from an i/o pin (that can read serial)
the [adafruit tft display] mentioned above also uses the gpios to connect to the pi - in particular it uses 5 spi pins and two standard pin outs. by cross referencing the [raspi gpio] docs it does not use either of the rx serial pin , which would be needed if i were to receive midi directly (rather than through usb), it also leaves plenty of pins for receiving cv from a [mcp3008] through software spi for example. it is likely that my gpio lcd screen communicates with the pi in a similar way and that i could figure out a way to connect these extensions if desired. the [adafruit tft display] mentioned above also uses the gpios to connect to the pi - in particular it uses 5 spi pins and two standard pin outs. by cross referencing the [raspi gpio] docs it does not use either of the rx serial pin , which would be needed if i were to receive midi directly (rather than through usb), it also leaves plenty of pins for receiving cv from a [mcp3008] through software spi for example. it is likely that my gpio lcd screen communicates with the pi in a similar way and that i could figure out a way to connect these extensions if desired.
what follows is the interface of cheep lcd from the shop page :
PIN NO.| SYMBOL | DESCRIPTION
--- | --- | ---
1, 17| 3.3V | Power positive (3.3V power input)
2, 4 | 5V | Power positive (5V power input)
3, 5, 7, 8, 10, 12, 13, 15, 16 | NC | NC
6, 9, 14, 20, 25 | GND | Ground
11 | TP_IRQ | Touch Panel interrupt, low level while the Touch Panel detects touching
18 | LCD_RS | Instruction/Data Register selection
19 | LCD_SI / TP_SI | SPI data input of LCD/Touch Panel
21 | TP_SO | SPI data output of Touch Panel
22 | RST | Reset
23 | LCD_SCK / TP_SCK | SPI clock of LCD/Touch Panel
24 | LCD_CS | LCD chip selection, low active
26 | TP_CS | Touch Panel chip selection, low active
from this i should b able to work out which pins i can use for midi in and for analog-to-digital inputs (also piCapture needs some inputs too)
