I am pretty new to this all so forgive me if I didn't post this under the right community since I wasn't 100% sure which one to post in. I have a rangefinder that uses an HT1621B chip that sends signals to a custom 32-pin LCD. I am wondering if there are any MCU or board that has a 32 FFC cable connector that I could connect and then transfer those signals to where I want. I am probing the signals on the chip and am having a hard time decoding, mapping, and understanding the signals so I am trying to go around the chip and just go after the output that it is producing. If more details are needed let me know and I will do my best to give more.

 

Read the data sheet for the ht1621b. That shows the output config. You may be better off to read the input DATA pin (while WR is low), to see what is being sent to that display controller, and interpret that with a microprocessor instead.
That chip is just a display controller, the data comes from elsewhere.

 

What are you hoping to get from that data stream. If it’s sensor output, flush out the sensor input.

Sorry for the late reply, didn't get any notifications. I hope to get the raw data that goes from the MCU to the HT1621B chip as it goes to the different outputs to display the measured range. How would I flush the sensor output, roughly speaking?

 

‘Sensor’ in this application probably isn’t useful. My bad. I suppose you could filter out pixel info and extract useful data. As mentioned, reading the data line would be easier.

OK, I will try to learn more about that and try to do it. thanks!
