Hello!I work with STM32F429 nucleo board.I try to connect it to CC1125 by SPI.The requirement of SCK rise time is less than 40ns.I tried different SPI channels and SCK pins.Typical SCK rise time of the board is about 50 ns.How can I improve it?
I like the way CubeIDE generate the code. Especially with "Generate peripheral initialization as a pair of '.c/.h' files per peripheral". This is very helpful tools not only for start the project but also for checking particular functionality.Why exa...
MCU: STM32F030CCT6Programmer: ST-Link/V2Software: STM32 ST-LINK Utility v4.1.0.0I'm new to STM32 mcu's and trying to comprehend the memory map.The Reference manual (RM0091, DocID018940 Rev 9) states in section 2.5 that when the Boot0 (pin) is high an...
we use STM32F427IIH6,when we download the program the following error occurs:cannot reset target shutting dowm debug session;cannot access memory;internal command error;What causes the failure?see the attachment for further informationthank you!
Hi. i have some problem when verifying the board composed of STM32F030RCT7 with Keil IDE (MDK ARM). I still don't know much about FW, so I ask a few stupid questions.Problem 1. I am basically setting the project through STM32CubeMX. I checked that t...
Hello,I am taking the liberty of writing to you for information on the calibration of the RTC.At present the RTC uses the HSE clock. The HSE clock is derived from a 25MHz quartz and then divided to be at 1MHz. This quartz has a tolerance of 20ppm.The...
Hello,https://www.st.com/en/embedded-software/i-cube-netx.html#overviewFrom this link, I am working for the PROFINET protocol using STM32F7 host and as given example it has worked for SPI interface.However, my requirement is to use FMC interface and ...
Hello!I want to use a simple rotary encoder with STM32F429.I programmed the TIM4 timer into 'ENCODERMODE_X4' mode.Is there a way for me to detect the rotation of the rotary knob by interrupt?I don't want to do periodically TIMx->CNT sampling if there...
Hello,Somehow I can't get debug uart via virtual port to work. I have followed several youtube videos and and studied user manual for my board that claims that "USART1 is directly available as a virtual COM port of the PC".The system debug is Serial ...
I've been trying to connect a 8-bit LCD to FSMC of STM32F103ZET6. But it seems not working at all. Even the display ID could not be retrieved. So that is a complete failure!The LCD chip is ST7735S. This LCD works on other 8/16 bits mcu parallel inter...
