Hi i have a big Problem.
I have build the HAL with CubeMX 4.24 and i have configured that I2C3 had to Receive 128 Bytes.
stm32l4xx_hal_i2c.c
static void I2C_ITSlaveCplt(I2C_HandleTypeDef *hi2c, uint32_t ITFlags)
/* If a DMA is ongoing, Update handle size context */
if (((hi2c->Instance->CR1 & I2C_CR1_TXDMAEN) == I2C_CR1_TXDMAEN) ||
((hi2c->Instance->CR1 & I2C_CR1_RXDMAEN) == I2C_CR1_RXDMAEN))
{
hi2c->XferCount = I2C_GET_DMA_REMAIN_DATA(hi2c);
}
/* All data are not transferred, so set error code accordingly */
if (hi2c->XferCount != 0U)
{
/* Set ErrorCode corresponding to a Non-Acknowledge */
hi2c->ErrorCode |= HAL_I2C_ERROR_AF;
}
�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?
When i received a message, then the XferCount on Line 5 are bigger than 0 and the function where left with an Error.
What is wrong??
Best regards
Brian
