Description
I keep getting the following error when trying to use I2C2 pins A4(PA_12) and A5(PA_11)

I2C: unknown instance
Code works fine when I use any of the other SPI1 pins.
Checked the PeripheralPins.c file for the board and it seems fine.
example of code that would fail:
#include "I2CSlave.h"
#include "I2C.h"
#include <cstdio>
#include <string.h>
#define SLAVE_ADDR 0xA0
#define BUFFER_SIZE 6
I2C master(A4,A5);
static const char* to_send[] = { "abcde", "12345", "EFGHI" };
int main() {
char buf[BUFFER_SIZE];
int send_index = 0;
while (1) {
strcpy(buf, to_send[send_index]);
// Write the new message to the slave
if (master.write(SLAVE_ADDR, buf, BUFFER_SIZE)) {
printf("Failed to write to slave!\n");
} else {
printf("Written to slave: %s\n", buf);
}
// Read what the slave has (should be identical)
if (master.read(SLAVE_ADDR, buf, BUFFER_SIZE)) {
printf("Failed to read from slave!\n");
} else {
printf("Read from slave: %s\n", buf);
}
// Change the message we're writing to the slave
send_index++;
if (send_index > 2) {
send_index = 0;
}
wait_us(500000); // Wait 0.5s
}
}
Can anyone try this and see if they get the same result?
