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....
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 ...
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...
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 ...
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...
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 ...
i want to set gains of PID Kp,Kd,Ki by auto-tuning process but i dont know auto tuning process of PID. how can i do this?
Hi, I am using Stm32l4r5 controller for my project.I would like to configure lpuart in DMA + interrupt mode and want to read **** of any length.But code generated through Stm32cubeMX not allowing me to read variable length data through lpuart.Receiv...
Hello,I am having difficulty writing the serial communication in order to talk to the STP08DP05 LED driver. Should I leverage i2c/spi/uart or bitbang? is there already a library written for talking to this driver?Best,-Danny
Hi,there.I am using DAC60508 with my STM32F7，60508 is 12 bits precision，and with 24 bits command-length，SPI interface. After initialize the SPI，I send 3 bytes separately，and I use a oscilloscope to check the wave of SCL�?SDI�?CS，its seems right，but i...
