Hi, I have an application that should trigger an interrupt on a falling level signal. For argument sake, let's say that I expect it to trigger about once a second. Now, when I run my code, it triggers(the EXTI12 ISR) more like 30 times per second. I ...
New to CAN here,Is it possible to configure the same CAN peripheral (CAN1) on an STM32F4 to receive messages from one node in RXFIFO0 and from another node in RXFIFO1?The reason for this setup is that one of the nodes has a higher priority and I woul...
the same intervalthere is lag between themHi ,I use stm32f401rct6 board ,I need to generate two pairs of complemdntary pwm signal to drive 4 igbt for dc full bridge converter in soft switching way, How can achieve two pairs by some leg between them a...
Hi, I am developing a low power application using STM32L431RCTx of 64-pin QFTP package.I have gone through the manual and some web content and tried several methods. The minimum current consumption I could achieve is 1.33mA at 3.6V power supply. The ...
hi, I wanted to ask,I saw that the micro STM32H562 datasheet has a new DTS digital temperature sensor. I wanted to ask :1.what is linearity of this sensor?2.what is its max error?3.what is the level of accuracy?I see that it is new so I wanted to che...
Hey, I´m working on implementing all 3 CAN bus interfaces on a F767ZI. Looking through the Reference Manual it states that dual CAN set ups feature 28 filter banks and single CAN set ups feature 14 filter banks. However looking at Table 280 it states...
Hello, I am currently working with the STM32H7S78-DK board using STM32CubeIDE for setup. I have connected four external buttons to the following pins: D2 (PF1), D4 (PF2), D7 (PF3), and D8 (PF4) on the board. I have configured the buttons as external ...
Hi community,after searching quite a long time for a bug on my board I found it. It was due to an unclear phrasing of the stm32f411's datasheet in table8/p39: for the QFP64 package pin 13 is not only vref but also VDDA.It would be much clearer to wri...
Hi All,I am trying to run FreeRTOS and TouchGFX on an STM32H7S7I8T with TIM6 as the timebase source. I am running into an issue where uwTick is not incrementing, this is due to HAL_IncTick not being called. Tracing it back, HAL_TIM_IRQHandler is neve...
Thank you so much for your continued support. There is undershoot and overshoot in the waveform of the input pin on the STM32H7A3ZIT6. What is the acceptable duration (in nanoseconds) for it to be within specification? Please also check the attached ...
