Hello guys, I'm trying to simulate this simple code with Keil UV4..
//----------------------------------------------------------------------------- // Includes //----------------------------------------------------------------------------- #include <C8051F360.h> //----------------------------------------------------------------------------- // Global Constants //----------------------------------------------------------------------------- #define SYSCLK 24500000 // System clock in Hz //----------------------------------------------------------------------------- // Function Prototypes //----------------------------------------------------------------------------- void OSCILLATOR_Init (void); void PORT0_Init(void); void PORT1_Init(void); void PORT2_Init(void); void XBar_Init(void); //----------------------------------------------------------------------------- // Global Variables //----------------------------------------------------------------------------- //----------------------------------------------------------------------------- // main () Routine //----------------------------------------------------------------------------- void main (void) { PCA0MD &= ~0x40; // Disable watchdog timer // Initialize Port I/O PORT0_Init(); PORT1_Init(); PORT2_Init(); XBar_Init(); OSCILLATOR_Init (); // Initialize Oscillator while (1) { } // end of while(1) } // end of main() //----------------------------------------------------------------------------- // PORT_Init () //----------------------------------------------------------------------------- //----------------------------------------------------------------------------- void PORT0_Init () { unsigned char SFRPAGE_save = SFRPAGE; // Save the current SFRPAGE SFRPAGE = CONFIG_PAGE; // Switch to the necessary SFRPAGE P0MDOUT = 0x0E; P0SKIP = 0x0F; SFRPAGE = SFRPAGE_save; // Restore the SFRPAGE } void PORT1_Init () { unsigned char SFRPAGE_save = SFRPAGE; // Save the current SFRPAGE SFRPAGE = CONFIG_PAGE; // Switch to the necessary SFRPAGE P1MDOUT = 0x3F; P1MDIN = 0xFF; P1SKIP = 0x3F; SFRPAGE = SFRPAGE_save; // Restore the SFRPAGE } void PORT2_Init () { unsigned char SFRPAGE_save = SFRPAGE; // Save the current SFRPAGE SFRPAGE = CONFIG_PAGE; // Switch to the necessary SFRPAGE P2MDIN = 0xFC; P2MDOUT = 0xFC; P2SKIP = 0xFF; SFRPAGE = SFRPAGE_save; // Restore the SFRPAGE } void XBar_Init () { unsigned char SFRPAGE_save = SFRPAGE; // Save the current SFRPAGE SFRPAGE = CONFIG_PAGE; // Switch to the necessary SFRPAGE XBR0 = 0x01; XBR1 = 0x40; SFRPAGE = SFRPAGE_save; // Restore the SFRPAGE } void OSCILLATOR_Init (void){ unsigned char SFRPAGE_save = SFRPAGE; // Save the current SFRPAGE SFRPAGE = CONFIG_PAGE; // Switch to the necessary SFRPAGE OSCICN |= 0x03; // Initialize internal oscillator to // highest frequency RSTSRC = 0x04; // Enable missing clock detector SFRPAGE = SFRPAGE_save; // Restore the SFRPAGE }
and I'm using c8051F366. In the simulation I can see the values of registers are changing, but they are not graphically shown in the relevant peripheral simulation windows, next to register which is being changed. For example, if I go Port2 peripheral window, I can see the value P2MDOUT has changed to 0xFC but not ticks to indicate the bits which set and not set! I think this is a bug, or I'm doing some stupid thing which I cant figure it out.
Same thing happens for P1MDOUT, P1SKIP and P2SKIP with regards to the above code.
In my case, I can see the value P2MDOUT has changed to 0xFC but only 6th and 7th ticks are showing up (which equals to 0xC0 graphically). If I click the fifth check-box (which indicates the 5th bit of P2MDOUT) then the IDE automatically put ticks such a way that 0xFC is correctly showing up.

Hi Eric, Yes I know. But I was surprised as this is is pretty simple thing! The graphical representation of GPIO registers should be one of the most simple and obvious thing, which Keil should've tested, before they release their tool.
Cheers..

no, it is not, just to mention a few SILabs have several flavors of "port configuration" and the NXP LPC9xx have another.

Hi Eric, Thanks again.
Found a temp solution. I'm using a different device (different in name, but works similarly) for simulation, rather than the device which I'm writing the code. I'm using the simulation only for checking the peripherals and sometimes the interrupt system, as such simulating using a different device would not really matters to me.
