On STM32L475 using UART4 with DMA ring buffer after calling function HAL_UARTEx_ReceiveToIdle_DMA UART generates frame error.

Sometimes DMA is setup prior to frame error interrupt, sometimes after frame error it is not clear to me why. Problem is when frame error is detected after dma is set up then "HAL_UART_IRQHandler" function executes "UART_DMAAbortOnError".I can not de...

Resolved! TSC measurement after exiting STOP mode (Abnormal delta)

Hi,MCU: STM32L072MCU is using TSC and ST touch sense library. When there is no stop mode involved, the measurement delta of no pressing is normal (-1, 0, 1).If MCU enters stop mode and then exits stop mode for touch sensing measurement, the delta wou...

Resolved! Minimum pulse width for STM32F2 timer in input capture mode.

I have a low frequency (~1 kHz), low duty cycle signal that I'd like to capture rising edges of. What's the minimum width of those pulses to capture them using a timer in input capture mode?I see there's a programmable digital filter there, in terms...

Resolved! Why is does the ADC stay on 2048 (12Bit)?

Hello Our STM32G4 is measuring a sinus-ADC value with offset. The offset is at VDDA/2.Our ADC measurement shows a plateau at the offset, even, when the sinus signal is crossing the VDDA/2 (see attached picture).The signal them self seems to be ok (me...

How reinit UART?

After reset MCU init UART - 8bits, no parity bit, init DMA RX and TX, interrupts on - works Ok.Reinit UART - 9 bits, even parity bit, no DMA - works Ok.Reinit UART the same as p.1 - doesn't work interrupts.

Gimbal 3-axis with STM32 and MPU6050

Hi I have been thinking about making a 3 axis gimbal with Arduino and an MPU6050 for some time now. I went around the internet for a while and saw that there is a project that manages to control three brushless motors only with arduino as if they wer...
