DMX512 decoder: unable to get falling and rising edge using interrupt in input capture mode
details: using Timer 1 with channel 1 and channel 2 for falling and rising edge, and detect break MAB and data frame. code: /* USER CODE BEGIN Header */ /* USER CODE END Header */ /* Includes ------------------------------------------------------...
ADC with DMA
HI everybody,Using the STM32F103 series, I was able to configure a single channel with DMA and get ADC data, but I was unable to analyze any data or do any while loop calculations for the moment. I simply increased a variable to see if it was updatin...
Resolved! STM32L431 power consumption.
Hello.We are using PA3 pin as input with pin pull up enabled.Power consumption of the board is around 36 microamps when pin is not connected to ground.But when we connect PA3 to ground we have current increase to 74 microamps.I think that we have som...
Input capture interrupt skip happens sometimes, even if input trigger is present. How could that be?
I use timer with input capture mode, to be able to measure time period of an optical encoder pulse. I experienced that measured value rarely is twice as the expected one. I tried with different timer prescaler values, but same problem remained. Suspe...
Resolved! own unique ID
Hi, I am using STM32G0B1 MCU for my project. Is it true each STM32 IC has its own unique ID. For STM32G4 product has the UID facility. Is it 96-bit ID for all the stm32 families or is it different. Which manual has to be referred for this?If yes can ...
ThreadX status and future
Hi All,Not so long ago ST has selected Microsoft ThreadX as one of its its strategic technologies.In my opinion it is a very good RTOS. The problem is that it was supported by Microsoft only, no other community project integrates with it, e.g. mcuboo...
Resolved! STM32H7 UART - use FIFO and get per-character interrupt?
Hi The MCU is a STM32H735I will use the UART3 port for combined debug output and command line interfaceSo I would like to use the FIFO, it quite useful when sending debug data.The Fifo is also useful for RX, if e.g. interrupt is blocked by other inte...
W25Q256 write protection
Hi!Why can i not disable the protection? I use W25Q256. I can't write and erase the flash ic.The programming was working, but suddenly an error occurred during download. Here I noticed that the bits of SR 1 went to 1 and I can't reset them.What could...
Resolved! CAN2 on NUCLEOF446RE is not working.
I am working on NUCLEO F446RE, I need to use CAN1 and CAN2 on the STM32 NUCLEO-F446RE board. I tested CAN1, which works normally for sending and receiving data, but when I tried CAN2, it didn’t work at all. I looked for solutions in https://community...
