While doing a CMD_CALLLIST, CMD_REGREAD is the only way to read a register. Similar to CMD_MEMWRITE.

Discussion - EVE / Re: Modifying ESD project to work in low power environment with RTOS

Hi Louis Cloete,
As you do not need any touch screen functionality, I guess you want to update screen with sensor data, am I right?
You can use a global variable on ESD and connect it with the widget you want, example: A numeric label. Here is how to do it on ESD:
1. in Usr_Source_Files.c, declare the variable name (image 1.JPG)
2. In the page, connect the variable to a widget (image 2.JPG)
Export the project and you can extern that variable in your code.

We can use STENCIL to draw that
Code Select
EVE_Cmd_wr32(s_pHalContext, BEGIN(LINES));
EVE_Cmd_wr32(s_pHalContext, COLOR_RGB(0, 0, 255));
EVE_Cmd_wr32(s_pHalContext, LINE_WIDTH(10)); //inner circle
EVE_Cmd_wr32(s_pHalContext, VERTEX2F(5*16, 10*16));
EVE_Cmd_wr32(s_pHalContext, VERTEX2F(500*16, 300*16));
EVE_Cmd_wr32(s_pHalContext, STENCIL_FUNC(NEVER, 0x00, 0x00));
EVE_Cmd_wr32(s_pHalContext, STENCIL_OP(INCR, INCR));
EVE_Cmd_wr32(s_pHalContext, BEGIN(FTPOINTS));
EVE_Cmd_wr32(s_pHalContext, POINT_SIZE((uint16_t )((C1 - 5) * 16))); //inner circle
EVE_Cmd_wr32(s_pHalContext, VERTEX2II(240, 136, 0, 0));
EVE_Cmd_wr32(s_pHalContext, STENCIL_FUNC(NOTEQUAL, 0x01, 0x01));
EVE_Cmd_wr32(s_pHalContext, POINT_SIZE((uint16_t )((C1) * 16))); //outer circle
EVE_Cmd_wr32(s_pHalContext, VERTEX2II(240, 136, 0, 0));
EVE_Cmd_wr32(s_pHalContext, STENCIL_FUNC(EQUAL, 0x01, 0x01));
EVE_Cmd_wr32(s_pHalContext, STENCIL_OP(KEEP, KEEP));
EVE_Cmd_wr32(s_pHalContext, COLOR_RGB(R, G, B));
EVE_Cmd_wr32(s_pHalContext, POINT_SIZE((uint16_t )((C1) * 16)));
EVE_Cmd_wr32(s_pHalContext, VERTEX2II(240, 136, 0, 0));
EVE_Cmd_wr32(s_pHalContext, STENCIL_FUNC(ALWAYS, 0x01, 0x01));
EVE_Cmd_wr32(s_pHalContext, STENCIL_OP(KEEP, KEEP));
EVE_Cmd_wr32(s_pHalContext, END());
