Hi,I have a custom board with STM32F746 MCU and XPT2046 touch controller (Clone of TI TSC2046E). They are connected on SPI2 (no other devices on this bus), running at ~210Kbit/s.I couldn't get the touch controller to work correctly, so I've connected...
I'm developing on Linux and I would like to find a c++ library that simulates the behavior of the stm32 micro controller's family. I'm looking for something similar to simavr. is there something like that?
I am using STM32H750VB for my project. I am unable to configure parameters for MODBUS communication. When I activate Modbus communication using CUBE MX .I have attached the screenshot of the problem and also my cube version. I want to configure the b...
I am trying to use the JTAG pins for other purposes if possible. Is there a way to separate both programming and functional modes?
Hi all,We have an SDRAM connected on the FMC interface of the STM32H745, wired as in the attached screenshots.What is notice is that i am writing 0x12345678, but i get 0x12341234. This is one, the other is that also these values are gone after some t...
I work with SAM3X8E microcontroller (datasheet : https://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-11057-32-bit-Cortex-M3-Microcontroller-SAM3X-SAM3A_Datasheet.pdf, page 676 to 707 for SPI)I want to make a multi transfer bytes thanks to SPI Bus....
Hi , I am working on stm32f070c6 MCU , in that by using adc ,I want to measure the resistance of resistor connected at adc pin, by using simple formula of ohms law , I want to know how much current sink at an single adc pin , by knowing of current(i)...
Hello community,I need to control RTS and CTS signals in my application.But, It looks like STM internally controls these signals.Can anyone suggest better way to control them in my application.Thanks,Hiren Bhuva
Hi Guys ! I am trying to record the activity of my MCU running RTOS . I am currently in efforts to integrate the segger system view for this particular usage. I am currently stuck in the process of RTOS Patching error . Can anyone provide suggestions...
Hi, i'm trying to use a single DMA channel to both read/write to the SDMMC. See here (https://community.st.com/s/question/0D50X00009XkWO5/getting-sdmmc-to-work-with-dma2-channel-4).When generating the SDMMC DMA configuration using cubeMX it results i...
