Hello, I don't have much experience with using DSP/BIOS. I would be very grateful if somebody could help me to solve the following problem. I would like to do something like this: ************ ********* ********* ********* ******** ***** *Procedure1* - *Proc.2* *Proc. 3*--*Proc. 1* --*Proc.2*--*etc* ************ ******** ********* ********* ******** ***** I wouldn't like to use PeriodFunc object (in continuous mode) which can be defined in DSP/BIOS which can start Procedure 1 because this function can break my procedure 1, 2 or 3 during the calculation. Also I can't set too long time which can be defined in PeriodFunc because between Procedure n and Procedure n+1 can't be any delay. I'm going to use the example program for THS1206evm device (AD converter) which is shown below. /* PeriodFunc is called every milisecond by DSP/BIOS and posts a StartConversion SWI to start a new conversion void main(void) { ................................................ /*few settings */ TIMER_Start(hTimer); } void BlockReady1206(void *pDC) { SWI_post(&SwiDoCalculation); } void StartConversionFunc() { dc_rblock(&Ths1206_1, ad_buffer, BLOCK_SZ, &BlockReady1206); } void DoCalculationFunc() { ............................................ } void PeriodFunc() { SWI_post(&SwiStartConversion); } What should I change in above program? How can I avoid using PeriodFunc object in continuous mode (I know that I can change setting of PeriodFunc into shot mode but I would like to call Procedure 1 when Procedure 3 is finished)? I tried to set one shot mode (settings of Period Func) and use SWI_post(&BlockReady1206)- in the procedure void DoCalculationFunc() in above program but without any success. Can anybody correct me? Thanks in advance, Poul |
How can I avoid of using Period Function Manager in DSP/BIOS?
