Hello I am working on MCUxpresso IDE and want to interface 7-segment display with LPC1769. I am using 3-digit seven segment and my goal is to display 3 digits. I did some code using the APIs which are present in LPCopen's e.g. After flashing the code to target, 7. 7. 7. gets displayed after some delay and if I change the data e.g. if I pass other numbers like 0,1,2 ..... the same gets displayed(7.7.7.). Do we need to clear the data? And how to clear that? I tried to find the API in the example and I found Chip_GPIO_SetPortOutLow to make the whole port low. I am not getting where the fault is. Is there any sample seven segment example for MCUxpresso? I am attaching the code kindly help me. Thanks in advance!
