Hi, I'm trying to connect my STM32F411CEU6 to my laptop by using USB to TTL. The USB to TTL I use is FTDI FT232RL module, and I connect my STM to my FT232RL like these following (FT232RL -> STM32):VCC -> 5VGND -> GNDTX -> PB7RX -> PB6Then, I connect...
I'm OEM, I bought materials such as component and IC base on my customer's gerber file, BOM and manufacture PCBA or finished products for them. recently one of my customer's products needs STM32F407ZET6. first phase, 50pcs of PCBA no problom, second ...
Hello, i work with STM32F407ZG MCU, i need to place functions in RAM and CCMRAM sections. Placement of functions in RAM is correct, but they take longer than in flash. If I place functions in CCMRAM, then when I call the function, I get an error Hard...
Please Reply ASAP
I want to send data on SPI3 via DMA in TIM2 ISR but something is wrong. The data sent is always 0. Can someone please have a look what I miss here? This example is made for STM32U5 Nucleo board with CubeMx.
Even though it is not really advertised as having changed a lot, it looks like the U5 increased the throughput of the PKA unit nearly 3 fold (upper L5, lower U5):Is this really the case or did the way of obtaining those numbers change in between (e.g...
Hello,I would like to measure the period of a square wave (around 1 kHz) with a timer in input capture configuration. I am using TIM5_CH3 on pin PA2 (nucleo G474RE).I would like to receive a bit of help in debugging my code since i am not able to mea...
Hi, I am a newbie in stm32. I am trying to receive DMA from USART1,USART2,USART3.But I am confused as how to do it because, all of them go inside same routine of DMA. Therefore how do I distinguish between different usart. my controller is stm32f103c...
Is there a way to programmatically exit from mute mode ? It seems that MMRQ can only be written to '1' to put USART in mute mode, but there isn't the possibility to return to a 'normal' behaviour by software. Any info to share ? Thanks
I have a programme running under Cube IDE. How can I run the MCU and its peripherals without powering up the ST-Link and its components on the DISCO board. Thanks for your help.
