How to manage 2 channel PWM with DMA - STM32L073
We try to generate audio signal with 2 PWM signals. We use TIM2_CH1 and TIM2_CH2 with DMA1 channel 5 and channel 3. This two PWM signals must be synchronized, but we noticed some delay between this 2 channels, which unfortunately is not constant. For...
In Rx Polling Mode, HAL_UART_Receive() is stuck in UART_WaitOnFlagUntilTimeout() waiting for the RXNE flag to get set in the UART's Status Register.
I'm using a STM32F407-Disc1 board, and my polled HAL_UART_Receive() is stuck waiting for the RXNE flag to get set in the UART Status register. Ironically, when using the STM32CubeIDE debugger and looking at the SFR registers for my UART, it looks li...
STM32U5 ADC internal channel
Hello,I'm facing some issues sampling ADC internal channel in of STM32u575.In particular these are the steps I'm following:VDDA enableADC Clock ConfigurationHAL_ADC_Init (&ADC_Handle[i])Interrupt configuration.Then, I configure the ADC channel to rea...
Resolved! VREFINT - sporadic false(?) readings
Using a STM32F091 board, I set up the ADC to:sample at the longest selectable sampling time (239.5 cycles)clock source is the internal 14 MHz RC oscresolution 12 bitsequence of all available channels incl. vrefintAt startup, there is a slight deviati...
STM32U5 controller RTC accuracy
Hi,I am trying to enable RTC functionality in Nucleo STM32U575ZI board. As one of my requirement I wanted to understand how much accuracy we can get for STM32U5 controller ? Any documentation or suggestion would help a lot.Thanks!!
I am using STM32F051K6U7 HAL_GetTick()
Hi ,I am using STM32F051K6U7 for one of our project.For Timing the HAL_GetTick() is low accuracy .every 240 seconds there are 1 to 2 seconds off .I am using a f0discovery board, so I am using internal RC occilator. Is this expected or is there an er...
Someone has ported the libtwolame or other MP2 encoder library to STM32 series?
My idea is to use the I2S input and encoder a stereo pair in MP2. Someone have successfully ported the libtwolame (or other MP2 encoding library)? The STM32F4 or F7 CPU is fast enougth to accomplish this task?
How to send ATR commands in STM32L0x?
I have connected ISO 7816 to my STm32L011G4u7. I am new to programming. Can you please temm me how to initialize smart card and send the ATR commands?
aci_gatt_update_char_value returns undocumented error code
Modified the BLE_Throughput example to use indication characteristics instead of the notification.I also set the interval to 1 second for debugging purposes because I saw that only 1 IND is read by the client per connection interval.I see that SendDa...
