Dear all,

I am using STM32F10ZET6 microcontroller. I have a query related peripherals interfacing with MCU.

Question:

How do I interface 8-bit peripheral chips like MT8980 (Digital Crosspoint Switch), M34116 (PCM Conference Chip), etc with the STM32F103ZET6 MCU?

In the memory mapping diagram, there are FSMC banks used for memory mapping. Kindly tell me what should I do for the I/O mapping at which address locations?

reply as soon as possible.

regards,

Hi,

it is sometimes easier to talk with external components via direct using the port. You may configure portbits 0-7 for data and portbits 8-15 for handshake: CS, RD~, WR~ ...

Then set and reset the bits by portpin access. This works fine if you don't have to much data to transfer.
