Question
How select address for I2C multislave stm32l4 in interrupt callback ?
My target is select more slaves in callback I2C RX , I have tryed with
void HAL_I2C_MasterRxCpltCallback(I2C_HandleTypeDef *hi2c)
{
if (hi2c1.Instance->CR2 & I2C_CR2_SADD == I2C_ADDRESS)
{
..
...}
}
but don't work !!
When I try to use the field in static void MX_I2C1_Init(void) :
hi2c1.Init.OwnAddress1 = 0xA0; (address slave 1)
.
.
-
hi2c1.Init.OwnAddress2 = 0xA2; (address slave 2)
In this case when i put the filed in callback rx I"C the condition is verified
void HAL_I2C_MasterRxCpltCallback(I2C_HandleTypeDef *hi2c)
{
if (hi2c1.Init.OwnAddress1 == 0xA0)
{
..
...}
}
My question is how can addressing 5 slave I have just hi2c1.Init.OwnAdd2 ess1 and
hi2c1.Init.OwnAddress2.
It's very important for my company ,i lost 4 days with no results.
BR.
