Hi all,I interfaced STM32H743 with external ADC(SLAVE) In master receive only mode. STM spi clk is distored seen on CRO above 20Mbps . But clk is fine till 20 mbps.so due to this received ADC values is not correct.but works fine below 20Mbps.So ...
Hi,I’m using stm32f103 as slave transmitter with arduino uno as masterAs far as I understand the stm sends the data bytes correctly then waits for ack for the last data byte but arduino sends stop instead of ack, stopstm ack failure flag is raised an...
I am relatively new to STM32 programming. I use STMCubeIDE (HAL & HAL_ex libraries) with STM32H743Zi and Nucleo-144. My configuration is:1 Multi Buffer DMA mem to peripheral, circular + clock triggered (54MHz per word, 360 words per buffer = 150 kHz ...
I have a project for STM32F3 using FreeRTOS.During debug, when I pause execution or a breakpoint is hit, stack trace info is only displayed for the currently executing thread, not all of my threads.However, if I look at the FreeRTOS task List, inform...
I assume this issue applies to DACs across all the MCUs but I am testing on a Nucleo-G431KB so I'll stick with the scientific facts.When I write a 12bit DAC value greater than 4060, the "down" slew rate in buffered output mode drops off a cliff.For...
Hi, I have a custom made board using a STM32L4 and I want to add some security to the data. So my flow diagram is: sensors get data-> data goes to L4-> L4 inicializates RasPi and passes the sensor data -> RasPi send back seured data to L4Is this some...
Can anyone please tell me the difference between VDD,VBAT and Voltage regulator in stm32f407vgt6 discovery board
Hello.I have assembled the device on the STM32L496ZGT6P microcontroller. Along with the other functions, this controller is to poll its UART interface (more precisely, UART4). The device is operated outdoors and at low temperatures, and I have notice...
I compile using IAR Embedded Workbench, and download the code.Recently, the chip was changed from STM32H753 Y to VI.I tried to insert the code used in the Y version into the VI as it is, and I issued the following warning in IAR.Mon Mar 09, 2020 09:2...
Hi Everyone.Page 524, section 18.4.16 ADC timing of the STM32L476 Ref manual states.The elapsed time between the start of a conversion and the end of conversion is the sum ofthe configured sampling time plus the successive approximation time dependin...
