Hello, I'm able to use system view as you described. But i can only be able to assign 8kb of buffer. If i increases buffer size it is not working while i've 30kb of free ram[assigning buffer in int sram]. While assigning it in ext sdram nothing is visible in systemview. Is there anybody who have the same problem and solved it? Thank You, Jigar Patel

Updation related to custom designed widget

This process call Paint event whenever WM_InvalidateRect() function executes even when transparency disabled. It consumes much more time than available. I've created custom graph widget for fill type look with transparency flag disabled. For fill type look i'm drawing line from offset to value. Is there any way that i can only draw single line and update it to display.
