Posted on July 25, 2016 at 23:29Hi, I am trying to stream a 1024 sample buffer to PWM in timer1 channel1 using circular DMA. But how will I control the speed of streaming from RAM to PWM at 44KHz? I couldn't find any option like triggering option...
Posted on July 27, 2016 at 05:06The processor is an STM32F373VCT6. I am software triggering SDADC1 every second using this call each time: HAL_SDADC_InjectedStart_DMA( &hsdadc1, (uint32_t *)SDADC1_Data, SDADC1_Data_Size ); The DMA buffer size has 20...
Posted on July 26, 2016 at 17:28I have been using a busy for loop to create my delays, but now I need precision. I want a function that will wait for n microseconds. How should I go about doing this? The Systick timer is not accurate enough (already...

Posted on July 26, 2016 at 15:19 Hello, I ran into a problem when trying to configure ADC DMA on STM32F103 microcontroller. I am able to get the data from ADC, however I am unable to get into the main loop of the program. I tried chang...
Posted on July 26, 2016 at 16:58Hello,I am using STM32L151RCT6 for communicating to an I2C slave.With last STM32Cube release V1.5.0 everything works fine. But with new version I always get HAL_TIMEOUT when I call method HAL_I2C_Master_Transmit() in...
Posted on June 29, 2016 at 15:58I am seeing an issue on the STM32F207 where if an I2C transfer fails the TxE bit is never cleared, causing the I2C2_EV_IRQHandler( ) to continuously get invoked and the overall system to hang. I know this isn't a lot ...
