SOLVED - X Nucleo PLC01A1 : porting to F7

Lagodolio · ‎2018-10-23

After writing some code for PLC01A1 and STM32 F446RE, I'm trying to port it on my F767ZI.

PLC Board uses SPI PA5, PA6 and PA7 for CLK, MISO and MOSI, and F4 & F7 have the same pinout.

In addition PLS01A1 uses F4's PB10,PB6 and PC7, but the same pins are named PE9,PD14 and PD15 on F7.

To sum:

F4 F7

B10 E9

B6 D14

C7 D15.

I changed x_nucleo_plc01a1.h given by STM so I have:

.....

//#define VNI8200XP_ENABLE_PORT           GPIOB
//#define VNI8200XP_ENABLE_PIN            GPIO_PIN_10
  .....

The code (that is the same used for F4, with "f4xx*.h" headers substituted by "f7xx*.h") is correctly compiled but PLC doesn't work ...

GPIO B10,B6 &C7 seem used as generic GPIO, but PLC01A1 is declarated compatible with F1,F3 and F4 and F7 isn't named so: is it possible that xnucleo doesn't work on F7?

Thanks far all,

Mario

SOLVED!

I didn't correct initial values...

:o

#define VNI8200XP_CS_CLK_ENABLE()       __GPIOC_CLK_ENABLE();
#define VNI8200XP_CS_PIN                GPIO_PIN_7
#define VNI8200XP_CS_PORT               GPIOC

Now I correct it with:

 //NEW F7 Values
#define VNI8200XP_CS_CLK_ENABLE()       __GPIOD_CLK_ENABLE();
#define VNI8200XP_CS_PIN                GPIO_PIN_15
#define VNI8200XP_CS_PORT               GPIOD
 
 //OLD F4 Values
//#define VNI8200XP_CS_CLK_ENABLE()       __GPIOC_CLK_ENABLE();
//#define VNI8200XP_CS_PIN                GPIO_PIN_7
//#define VNI8200XP_CS_PORT               GPIOC

and works!!
