Would the Text Display and/or AutoCAD Slide Drawing examples from the Cortex M7 package port to the RP2040?

What you need to do is modify any calls to SPI.Init (SPI0 / SPI1?) and Timers.Init (-> TIM0), and to modify the pin configuration code in the display driver module ST7735.ConfigurePins to suit the Pi Pico.
We are planning to test this ourselves as part of the Astrobe for RP2350 final tests early next week and will report back here if you haven't had any success by then.

The following connections between the
Pi Pico and the
AdaFruit 160x128 TFT display breakout board have been tested successfully:
Code: Select all
Display Pi Pico
------- -------
Gnd 3. GND
VCC 36. 3V3 (OUT)
RESET 9. GP6
D/C 10. GP7
-
CS 12. GP9
MOSI 15. GP11
SCK 19. GP14
-
LITE 20. GP15
The corresponding procedures in the RP2040 display driver module
ST7735.mod are:
Code: Select all
(* ========================================================================= *)
PROCEDURE ConfigurePin(VAR pin: GPIO.Pin; alternateFunction: INTEGER);
VAR
config: GPIO.PortConfiguration;
BEGIN
config.mode := GPIO.Mode_Out;
config.alternateFunction := alternateFunction;
GPIO.Configure(pin, config)
END ConfigurePin;
(* ========================================================================= *)
PROCEDURE ConfigurePins;
BEGIN
pinRESET.no := 6;
pinDC.no := 7;
pinCS.no := 9;
pinMOSI.no := 11;
pinSCK.no := 14;
pinLITE.no := 15;
ConfigurePin(pinRESET, GPIO.FSIO);
ConfigurePin(pinDC, GPIO.FSIO);
ConfigurePin(pinSCK, GPIO.FSPI);
ConfigurePin(pinCS, GPIO.FSPI);
ConfigurePin(pinMOSI, GPIO.FSPI);
ConfigurePin(pinLITE, GPIO.FSIO)
END ConfigurePins;
