Question
STM32F2xx_HAL_Driver : error in the driver TIM with DMA usage
Posted on March 25, 2016 at 12:18
Hi,
I use a CubeMx V1.0, version 4.14.0.
Firmware Package SMT32F2 family, V1.3.0 / 20-November-2015.
There is an error in the file stm32fxx_hal_tim.c, in HAL_TIM_IC_Start_DMA function.
The problem is the beginning of the code, with the handling of the return state.
if((htim->State == HAL_TIM_STATE_BUSY))
{
return HAL_BUSY;
}
else if((htim->State == HAL_TIM_STATE_READY))
{
if((pData == 0 ) && (Length > 0))
{
return HAL_ERROR;
}
else
{
htim->State = HAL_TIM_STATE_BUSY;
}
}
In my application, I use 4 channels of the same TIM with DMA requests.
If we start a DMA with one channel of TIMx, it is impossible to start another DMA channel of this same TIMx, because the HAL returns always BUSY.Can the ST team update this driver ? Since it's a part of the drivers used by CubeMx, it's a very annoying problem.
Thanks :)
