Hi all
I am struggling to get the I2C up and running. I set the clocks and initialisation up in CubeMX (latest version) and when debugging the code I keep getting the pclk1 variable coming back with 1000000 which is below the limit so I get a HAL_ERROR.
The APB1 Peripheral Clock is set at 36 MHz, I am using a 25 MHz HSE crystal. All other peripherals are running fine.
I am clearly setting the clocks up incorrectly. As when I do a MasterWrite I don't see anything on the line.
Anyone with any ideas.
Regards
Nick
/* Get PCLK1 frequency */
pclk1 = HAL_RCC_GetPCLK1Freq();
/* Check the minimum allowed PCLK1 frequency */
if (I2C_MIN_PCLK_FREQ(pclk1, hi2c->Init.ClockSpeed) == 1U)
{
return HAL_ERROR;
}
