CC2541: Delay function for CC2541 in simplebleperipheral project

Vito Ventura

Part Number: CC2541

Hello,

i'm developing using IAR for CC2541. Need a delay function in the simplebleperipheral project, I read about HalLcd_HW_WaitUs () function but i cant find it.

Can anyone help, please

Regards,

Vito

Hi Vito,

I suggest you use an OSAL timer for that purpose, similar to the periodic event.

Hi Joakim,

I created the event and used the osal_Start_timerEx function, but it doesn work. Im developing using simple ble peripheral project on cc2541. After 10 seconds of advertising (general mode) i have to toggle a gpio pin. So I inserted the function

osal_start_timerEx( simpleBLEPeripheral_TaskID, SBP_DONE_EVT, SBP_DONE_EVT_PERIOD )

in the GAPROLE_ADVERTISING case to generate a 10 seconds timer. (#define SBP_DONE_EVT_PERIOD 10000)

Then i created the event, similar to the periodic event:

if ( events & SBP_DONE_EVT )
{
// Restart timer
if ( SBP_DONE_EVT_PERIOD )
{
osal_start_timerEx( simpleBLEPeripheral_TaskID, SBP_DONE_EVT, SBP_DONE_EVT_PERIOD );
P1_7 = 1; //GPIO pin toggle after 10 seconds
}

return (events ^ SBP_DONE_EVT);
}

Can you help me please?

Regards,

Vito

Have you set breakpoint in code to verify that it does not work?

Where are you clearing P1.7. To Toggle you should XOR the bit:

P1_7 ^= 1; //GPIO pin toggle after 10 seconds
