Hello ST community,I can't find on the st.com website the documentation showing the electronic circuit of the STM32F411RE, especially for the user button. In which document can I find it?On the web it seems that schematics from google image show that...
I have an STM32H745 (Dual Core).. I'd like to verify the integrity of the M7 Core's Flash memory.Is there any built in way of getting the checksum (perhaps something that St-Link Cube Programmer uses), or is the only way to write my own function?
Hi,Im new to stm forums so sorry if i make any mistakes.Im using a stm32f103RET6 since i am familiar with f103 and i need usb/other peripherals. Thus far everything works great. However...Im trying to offload some work from cpu to DMA by sending a pr...
So, I'm trying to read data from a dht11 sensor. In the datasheet says that you have to send high signal, wait 80ms, then low signal, and dht11 will start sending data.My problem is, I don't know how to debug this. I don't know how to see if I my sen...
Hi,I'm having trouble getting PWM output on my STM32F303. I'm using CubeMX for pin config, then generating for Make for use with VSCode on Ubuntu. TIM1_CH3 has been configured for PWM output on PC2, and TIM1_CH2 on PC1. CH2 works as expected, while C...
My question might sound "strange" for HW experts.My STM32U5A5 MCU has DCache (16KByte). Datasheet says: used when external memory is connected (e.g. NAND/NOR flash, OCTOSPI).DCache is not used for internal memory (when running from MCU flash or inter...
It has been asked several times, however I can not find a working solution for me.With STM32L486RGT6 I achieved to implement jump to bootloader, entering DFU mode successfully. All fine!Doing it similar for STM32L071CZY6TR and STM32F469VE it does not...
What I want to do is send Write Enable instruction to external Flash and erase.The environment is as follows.Use Board : nucleo l4r5ziIDE : Atollic TrueSTUDIO® for STM32, Built on Eclipse Neon.1a.(Version: 9.3.0)FLASH : W25Q64JVThe connection diagram...
Hello.We are trying to read measured voltage by MAX17201 chip - register 0x09.But we are receiving incorrect value - 0x936A when battery voltage is 3.0V?!We are using I2C communication protocol.Here is the I2C initialization:static void MX_I2C1_Init(...
My project use STM32U595 chip. It will use HS USB to send large amount data to computer.I use NUCLEO-U5A5ZJ-Q for testing.The project use Ux_Device_CDC_ACM in NUCLEO-U5A5ZJ-Q of STM32Cube_FW_U5_V1.4.0.I reference this post https://community.st.com/t5...
