PIC16F913 and LCD in FlowCode

Post by Motions »

Has anyone used a 16F913 LCD driver in FlowCode? Is it even possible to do?

Let me rephrase. The 16F913 is not my concern. I need to know how or if you can use 7 segment LCDs in FlowCode. I'm using single digit 7 segment displays and which are not included in the component list.

Let me be more specific. Here is the LCD I need to use (http://www.lumex.com/specs/LCD-S101D14TR.pdf)

How can this be implemented within FlowCode?

Hello

The device you are looking at is a 7 segment display. You will see there is a component for a single 7 seg as well as for 4 combined 7 segs. The datasheet lists some of the pins as being common. You would have to find out if the devices are common cathode or common anode eg do you supply power through the common pins or supply power through the data pins.

Thanks Ben.

I was told it can't be driven like a standard 7seg LED because the LCD requires an AC power signal. How is this dealt with in Flowcode?

Ah yes I see that the device is AC now.

Would it be possible to use a standard digital 7 seg? My guess is that these would be MUCH cheaper.

Otherwise you will have to switch between a common cathode and a common anode configuration at high speed. Flowcode is not capable of this but it is possible using C though I imagine quite complicated and a lot of work for no real gain.

Unfortunately, no. The project requires LCD because of the large size and weight.

The 16F913 has the internal display driver but I'm not sure how much that has to do with Flowcode. I may have someone write it in asm.

Hello,

No im afriad Flowcode does not support the internal display driver directly. Perhaps one of our freelance engineers will be able to give you some help to get this working.
