Hi,
I’m doing some tests with I/O speed on W7500P and I am achieving only 2MHz on the following code:
[code]
DigitalOut myled(PC_8);
int main() {
*(volatile uint32_t *)(0x41001014) = 0x0060100; // set to 48 MHz
while(1) {
*(volatile uint32_t *)0x44000000 |= 0x100; // IO high
*(volatile uint32_t *)0x44000000 &= 0xEFF; // IO low
}
} [/code]
If the core clock is 48 MHz, how much is the FSB? Is there any way to speed up the I/O transition? I’m implementing a 16bit display and need faster I/O.
Environment: mbed and WIZwiki-W7500P
Best regards,
