I’m using mbed studio with mbed os 6.11.0, and running a test program of I2CEEBlockDevice with mbed LPC1768 board and 24C32 external I2C flash. I just copied the sample program from
I2CEEBlockDevice.h, and modifide a phrase to
I2CEEBlockDevice i2cee(p28, p27, 0xa0, 8*4096);, and added more
printf phrases and a LED. As for the IC chip, I connected pin 5 and 6 (SDA, SCL) to p28 and p27, connected pin 4 and 8 (GND, VCC) to GND and VOUT, and remained A0, A1 and A2 floating.
However, it doesn’t work as I excepted. It was noticed that it took 7 mins 15 seconds to run the
i2cee.init(); phrase. I’m not sure whether there is something wrong since this is my first time using a storage chip. Can anyone help me? Thanks.
