I am trying to get the stm32L010 lpuart TX out of PA14. The datasheet says this is AF6. However, despite uart interrupts etc all working (so I assume the lpuart block is configured ok) I can get nothing on PA14. This isn't helped by the fact that PA1...
I just got https://stm32-base.org/boards/STM32F407VET6-STM32-F4VE-V2.0 which is my first foray into embeded. I also got https://www.waveshare.com/wiki/4inch_Resistive_Touch_LCD which is TFT with XPT2046 touch. I have the LCD setup with FSMC 16-bit bu...
I found where we define the size of the screen but I could not find where the memory is allocated for the frame buffers. Also, emWin is running on 256k of RAM but the screen is 480x800. How do we define the bpp? Is it something that is defined in t...
I have two DMA streams running on my code for passing a CAN message buffer in memory to writing onto an SD card(tx/rx). I'm planning of using UART or SPI to retrieve a GPS unix-time stamp (module), my question is what should I be concerned for in usi...
Hi,i try to implement a idle line detection for my uart interface. I use this tutorial here: https://controllerstech.blogspot.com/2018/05/uart-using-dma-and-idle-line-detection.htmlIt is working on a STM32F103 (running example of the tutorial). So no...
Dear All,I have a newbie question about the DISCO board.I need 3 or 4 I2C buses, but from the documentation I can find access only to one.Is it possible to access all other I/O pins of the MCU STM32F769NI on this board?I will highly appreciate all yo...
Else do you have any method to calculate these data
I want to configure the ADC / DMA to read an analog input on STM32 CubeMX, but all pins which are available on the card are not linked to an "ADC _input" :sad_but_relieved_face: .should i use "analog_input "?how does it works? any help/advice is grea...
Hi there.I am currently programming on an STM32F469 Discovery Board. Can you tell me what settings I have to make so that the display always updates automatically. So that all values are always up to date?
I disable DMA channel global interrupt in CubeMX 5.6.0 by unchecking the corresponding checkbox. If I save and close the ioc file, the checkbox are checked again when reopening the ioc.
