 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

This has worked for me with the RP2040 before, but this is with an RP2350. SAVE IMAGE "RR-1.bmp" produces this image when sent with XMODEM S "RR-1.BMP"  Photo is:  (Or I'm doing something wrong.) PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Tested a RP2350 V6.02.00 and image arrived on the PC with bubbles intact. > gui test lcdpanel > save image "guitest.bmp" > files A:/ <DIR> . <DIR> .. 07:42 15-02-2026 4 bootcount 07:44 15-02-2026 38518 guitest.bmp 11:58 02-02-2026 4992 multi sensor, GPS & EEPROM reader.bas 2 directories, 3 files, 2445312 bytes free > xmodem s "guitest.bmp" > What do you get if you try:- CLS : LOAD IMAGE "RR-1.bmp" That will show whether the problem is with Xmodem or Save Image. If it is not saving the image the usual problem is between LCD_DO and MISO. If the screen is a ILI9488 you need the diode/resistor fix. IN4004 anode to LCD_DO, K to MISO. 1.8kΩ from MISO to LCD_CS. For other screens test continuity from the top of the LCD_DO pin to the top of the MISO pin. If the touch T_DO pin is connected to MISO you must either enable OPTION TOUCH or add a 10K pullup resistor to T_CS. Otherwise T_DO can go low and block all other input to MISO.
