Need help setting up DMA on STM32F1 & F4
Hi, I am trying to set up an input capture with DMA on a F1 and a F4 chip. The documentation is confusing, and most tutorials don't work for my specific scenario. For a start, when setting up DMA using cubeMX, I can't configure source, destination an...
Changing GPIO pin from PWM to Digital Output at run time
Hello, in STM32F10x, I need to use Stop mode. However, before going to stop mode, I need to stop PWM channels and leave them high (in output). How can I stop change some pins (A0 and A6) from timer PWM mode to normal output mode? I tried this method ...
Keeping Signed and Unsigned Variables or Values
I wonder about the keeping signed and unsigned values in proccessor.For example I have this define#define MY_NUMBER 8How to decide MCU number of "8" signed or "unsigned" value.How to convert binary number to keeping. For example I am doing static ana...
Resolved! How much flash the BSP_QSPI_Erase_Block() erases ?
I am using STM32F769I-DISO board with an MX25L51245G QSPI chipAs I understand it, I must erase before writing. So if I have 100 bytes of date on the QSPIand I want to change byte number 51 in my 100 byte data I should first eras this location.Howev...
Peripheral to peripheral DMA.
Hi all,I'm triybg to send data to a TFT from an external flash memory.I read than it is possible to comunicate 2 SPI peripherals trough DMA.I dont understand all the thing yet. Please can someone answer this:Lets say Flash is in SPI1 and TFT in SPI21...
Resolved! PSoc as I2C Master and ST as I2C Slave
Hi,I want to implement I2C communication between PSOC and ST.I've configured PSoc as I2C Master and ST as I2C Slave. I've succesfully transferred data from PSoc to ST but I'couldn't read data from ST.Here's the details about my implemention.When I us...
