4 digit seven segment display with stm32

[Bs.1]

Hi,

I am trying to interface the 4 digit seven segment display with STM32f3xx by using 74HC595.

I am using SPI between uC & 74HC595. If any one having reference for the same then it will be great for me to solve the display switching issue.

My data is display properly but unable to handle display switching .

Thanks in advanced.

How would this differ from driving a 4-digit 7-segment display from any other microcontroller?

"I am using SPI between uC & 74HC595"

Show a schematic - how is it all wired together?

"My data is display properly but unable to handle display switching"

What, exactly, do you mean by that?

What have you tried? Where are you stuck?

Again, the concept is independent of what microcontroller you use - so there are plenty of examples to look at online ...

I am using such 4 display modules connected in daisy chain.

i.e. clock, latch & digit enables pins for all four displays are connected together & data line is connected from one 74hc595 output to datain of 2nd 74hc595 and likewise....

Please post a schematic - trying to describe electronic systems in text is really ineffective. Especially in a non-native language.
