Hi All

i am driving a 26-Pin(4 COM+22 Segment) LCD display through

SPC56D-Discovery BOARD Using GPIOs & want to run a counter from 1 to 100 on LCD display.

please advise how it will be possible.

attaching datasheet of LCD.

i have displayed the all segments with the help of delay logic & running the lcd at 50hz.

Pls advise if any in-built lcd driver is there in SPC560D40L1 mcu, as i am unable to see in its datasheet.

Regards

Harsh

Hello Harsh ,

There is no built-in driver

Yes , it is possible.

Could you give me your LCD Reference ?

This LCD is supporting I2C ?

We have already implemented some LCD drivers with I2C (sw emulated) to reduce the number of wires

Best regards

Erwan

2.Storage temperature: -40 to 95 deg C

3.Operating Voltage: 5V

4. LCD Type: TN Positive

5.Connection type: Pin type

6.Clock viewing: 6'o clock

7. Drive condition: 1/4 DUTY, 1/3 BIAS

8.Display type: Trasflective

9.Polarizer colour: Grey

Hello Harsh ,

There is enough GPIOs to handle a TN Positive LCD. (cf screenshot)

you should create your own driver by creating a new component or new drivers in SPC5Studio.

I am checking in application team if some examples are existing.

Best Regards

Erwan

Hi Erwan

Please let me know if there are any example codes available for this.
