Hi Everyone, I am presently working on 56F807EVM board and have CW ver4.1. I work without using the motorola SDK. I am experiencing some problems, I have tuned the timers, e.g. Tmr_A_0 to produce a 30 Hz pulse waveform. I output the waveform onto the scope (+ve edge of the BNC cable from the scope connected to the Tmr_A_0 pin on J18 and the -ve edge connected to the Gnd pin). There is no break in the signal been produced as long as I let the program run. But when I read, say e.g. the timer's counter onto the console, using the printf statement, sometimes the DSP seems to push itself into a suspended state. In such conditions, though the signal is visible on the scope, what appears on the console halts after printing a few readings. Could someone please clarify, whats going on. Below I have inserted the model code as a seperate routine, the one that I use to tune the timers. Thanks in advance. void clk { TmrA3_CTRL = 0X5184; TmrA3_SCR = 0X00C1; TmrA3_CMP1 = 0X1FFF; TmrA3_CMP2 = 0X1FFF; //generate < 500KHz pulse printf("%d\n", TmrA3_CNTR); return; } thanks again. Ritu. |
