Run code from external RAM
Hello,for a new project I plan to execute the code from an external SRAM connected via FMC.Are there any experience on speed leakage?In an other Topic I read that there are losses of 4 times the speed compared to the embedded Flash.https://community....
resetting the WWDG
Hey everyone,I'm a little confused. I've added the wwdg, but I'm not sure where to refresh it. Is there somewhere I can refresh it that should happen at a constant time, The examples I looked at simply place the reset in the code, but I have so many ...
Resolved! NUCLEO-F722ZE I2C2 in slave mode doesn't work nothing.
Hi,I am using NUCLEO -F722ZE board for testing the STM32F7 and their peripheral features. Other peripherals I tested works fine, but I have encountered a problem with I2C2 in slave mode, that doesn't send ACK when the master calls it (status flags ke...
GPIO Speed
Hello everybody,I have to generate a pulse with very narrow and different widths. The setting and procedure is as follows: Clock Freq = 16 Mhz, Prescaler = 1. off time should be 15 μs, thuss = 15 μs * 16MHz / 2 = 120 Counts and with this logic for ...
Why placing breakpoints after enabling and starting USART DMA transfer in STM32F429I Discovery board corrupts my program execution?
Hi EveryoneI am working on a FreeRTOS based application in which I have to enable USART DMA channel to transmit 16 bytes of buffer from memory to USART Data Register in a task. It happens every time my task is invoked. Everything seems to work fine u...
multi master spi
Hey everyone,I've been struggling with the multi-master spi. I can send and receive seperately but when I try to integrate it into one program it bogs out. My understanding is that I can set the SPI line as a slave and then whenever I want it to act ...
