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...
Hi.I want to use interrupts to wake up from STOP2 and minimize the power consumption.The internal pull-up of 30k - 50K leaks about 100 uA when pulled to 3V3, so I was wondering how big can be a pull up in order to minimize this consumption. Ideally, ...
Could we used the SPI interface control the 5V LED Driver IC?STM32L412's VCC is 3.3V, SPI's pins are FT_f type.LED Driver IC's VCC is 5V.Is there anything that needs extra attention?Will there be problems with SPI operation?
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...
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...
HelloI designed a card with STM32L052C6T6 mcu, but I can't find this mcu in Turkey.What would you recommend as a pin to pin instead..I found stm32f103c8t6 but if anyone else please advise
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...
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.
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...
I'm looking for a trace port analyzer. Does anyone have any recommendations?
