I use FSMC in STM32F407 to access external SRAM IS62WV51216. I read RM0090 and AN2784, gives me two fomulatSU means here is the timing graphhere is write timing graphwhy WE have two falling edges on the leftwhat dose tSU tV mean,where is it in the t...
I am developing my own driver for a STM32 MCU, however I always get the same error when I try to compile the code. Here is the entire code from all the files I developed.There are always 8 errors, saying that pGPIOA, pGPIOB, pGPIOC, pGPIOD, pGPIOE , ...
I'm using a B-U585I-IOT02A discovery kit that that has the STM32U5 MCU. I'm looking to evaluate if the STM32U5 MCU can run an FFT in real time and how to evaluate the performace of the STM32U5 MCU running FFT's. Are there any tools to help me do that...
I am using L476RG ST board, and I recently purchased a GM95 QR scanner that supports standard TTL-232 serial communication. UART2 is configured to work with my PC using PuTTY as an interface, but how do I receive the data from the QR scanner and disp...
Hi.Is it possible to reconfigure one or some regions MPU without fully disabling MPU?I need configure for example ITCM memory for RW access when load code and set to RO mode after code copied completed.Code copied from SDRAM to ITCM, so MPU needed fo...
I am using cube mx for my design and I have some peripherals (ADC, Timer, I2S2, I2S3). I am making streaming by usb of some of them. I want to stoop i2s modules when i am not using it becouse affect to other modules sampling rate.By default Cubemx m...
Hi ! I am receiving data through UART using DMA to a buffer of 10 bytes. I want to always receive to the uartBuffer[0]. Thank you!
I am trying to implement a Phase Locked Loop in a microcontroller STM32. I have a reference signal and feedback signal which has $\phi$ difference wrt reference signal. For the moment, I am not using a real time feedback signal, rather simulating it ...
I use ADC2 and ADC3 (with HAL_ADC_Start_DMA) with no problem, just having problem with ADC1. I'm using FREE-RTOS. STM32CUBEIDE.
