[. . . ] CTRL_T1START is the width of the EXPOSURE1 pulse and also controls the time at which the EXPOSURE1 pulse is sent. When timer1 reaches the value set for CTRL_T1START, the EXPOSURE1 signal being sent to the camera goes high. When timer1 reaches zero, the EXPOSURE1 signal goes low. The EXPOSURE1 signal should be sent immediately to the camera upon arrival of an external trigger signal to indicate that exposure should begin, therefore CTRL_SET1CNT and CTRL_T1START must be set equal to each other; this is accomplished by setting CTRL_SET1CNTL equal to CTRL_T1STARTL and CTRL_SET1CNTH equal to CTRL_T1STARTH. PUL-CID-032 4 Application Note: DALSA CL-C8-6000A Interfacing non-standard cameras to Matrox Pulsar November 26, 1996 The Pulsar indicates to the camera that exposure should stop by sending the EXPOSURE2 pulse. For a given setting of CTRL_SET2CNT, which is the time set on the timer for EXPOSURE2 (timer2), the time at which the EXPOSURE2 pulse is sent is controlled by CTRL_T2START, the width of the EXPOSURE2 pulse. Timer2 starts counting down from CTRL_SET2CNT; when it reaches the value set for CTRL_T2START, the EXPOSURE2 signal being sent to the camera goes high. When timer2 reaches zero, the EXPOSURE2 signal goes low. Finally, it should be noted that the EXPOSURE1 pulse must remain high until the LVAL pulse goes low. Therefore, the time set on timer1 (CTRL_SET1CNT) must be greater than the sum of the exposure time, the maximum possible delay between the EXPOSURE2 pulse and the LVAL pulse, and the width of the LVAL pulse (the line transfer time). The maximum possible delay between the EXPOSURE2 pulse and the LVAL pulse is calculated to be 6. 4µs (4µs + 11 MCLK + 4 MCLK + 400ns or 4µs + 0. 73µs + 0. 26µs + 400ns = 5. 39µs maximum). The line transfer time is 199. 9µs (2988 pixels times at a clock rate of 15 MHz). So to summarize: CTRL_T1START = CTRL_SET1CNT, i. e. , CTRL_T1STARTL = CTRL_SET1CNTL and CTRL_T1STARTH = CTRL_SET1CNTH EXPOSURE TIME = CTRL_SET2CNT -CTRL_T2START CTRL_SET1CNT > exposure time + maximum delay between EXPOSURE2 and LVAL pulses (5. 39µs) + line transfer time (199. 9µs) Remember that each 16-bit register is split into a low and high byte. These values must be in pixels and must be set in hexadecimal; the value of each 16-bit register can vary between 0 (0000 in Hex) and 65 535 (FFFF in Hex). The registers are set in the following way: T2 user clock 14. 31MHz (clock source select) Hex CTRL_ SET2CNTL CTRL_ SET2CNTH CTRL_T2STARTL CTRL_T2STARTH DA 98 E8 1 34µs Decimal equivalent x user clock period 39130 x (69. 9ns) = 2. 7ms 488 x (69. 9ns) = 34µs T2= 2. 7ms PUL-CID-032 5 Application Note: DALSA CL-C8-6000A Interfacing non-standard cameras to Matrox Pulsar November 26, 1996 T1 user clock 14. 31MHz (clock source select) Hex CTRL_ SET1CNTL CTRL_ SET1CNTH CTRL_T1STARTL CTRL_T1STARTH CA A7 CA A7 42954 x (69. 9ns) = 3 ms Decimal equivalent x user clock period 42954 x (69. 9ns) = 3 ms T1= 3 ms When computing the hardware registers, the following question may be asked: "Some registers have been manually edited. Answer "no" to this question and to all questions that follow. These instructions must be followed very carefully; the only registers that should be modified are those mentioned above.
