Yes, I tried it with 300, 210 and 1.5k ohms.
According to the datasheet, the data has to be sent in between two latch pulses. I tried it the way you told but could not get output from output ports. I would like to ask if latch pulse is active high or low. latch should always be high I think but in datasheet latch is mentioned as low level active. The duration of clock pulse is also wide enough to read the data. In other posts on serial data that I referred, first low clock pulse is sent and after data, high clock pulse is sent. But I sent data first. Does that affect the transmission ?I also don't think that clock has to be sent repeatedly during latch and enable...
