Hi all ..! im working on a project and have to use cascade 4 to5 4 digit 7 segments with 74hc595 using esp-idf version 5 ,since i am not familiar with that software so the community support is needed if someone help me out how to do things it will be really appreciated . the need is to code on esp-idf for shift registers. THANKYOU
74hc595 is not really suitable for driving this kind of display.
Consider max7219. Each chip can drive 2x 4-digits and can also be cascaded. The circuit will be far simpler and work better.
This is the arduino forum. You will get advice about how to build your project with the Arduino IDE here, not probably no help using the esp-idf.
