Posted on October 06, 2015 at 19:46STM32F4xx HAL Driver Problem With I2C Write Data
I Want To Send Command In form of Int but in HAL Driver not Able to Send it and also Null Character for DS1621,
int main(void)

HAL_Init();
/* Configure the system clock */
SystemClock_Config();
/* Initialize all configured peripherals */

&sharpendif
Frequency is 168Mhz
please help me how to it work for DS1621 Digital Temp., Sensor
i get data always 0xFF80 while Standard peripheral Work well with F4 And F0
i Want to use it using HAL Driver because my other work is based on HAL driver
