Hello,

I have a question about Segment LCD Drive.

I found a Direct LCD Drive feature in PSoC4100 datasheet.

On the other hand, there is no same feature in PSoC4000S datasheet, so I thought that the PSoC4000S doesn't support Direct LCD Drive.

But the datahseet says LCD Drive Capability on page 1... Are they same features?

Is it possible to drive custom segment LCD (3com x 12seg) on PSoC4000S?

Hi YSJE_3566666

Both PSoC 4000S and PSoC 4100 devices have LCD Drive Capability. As mentioned in the datasheet of both devices, LCD controller can drive upto 4 commons and 32 segments with PSoC 4100 devices and upto 8 commons and 28 segments with PSoC 4000S devices.

I have shared a code example using PSoC 4000S device, in which the LCD component with 3 commons and 12 segments is used. Please have a look into the code example and let us know if further clarifications are required.

Also, We have filed an internal ticket to update the PSoC 4000S datasheet and mention 'direct LCD drive' as it's listed feature.

Thanks and Regards

Aashita

Hi Aashita

Thanks for your reply.

I found same things in PSoc 4100S / 4100S Plus / 4100S Plus 256KB / 4700S that are not listed in the Ordering Information Table.

Thanks and Regards
