Hi, I am trying to use STM32F103C8T6 standby mode and wake it up with wake up feature of RTC, but in CubeMX I don't see that this MCU would have wake up feature under RTC settings. How do I wake up this MCU from standby with RTC and wake up pin?
Hello,I need guidance on how to best implement a packet protocol to keep the data on multiple STM32F373 in sync with each other. If possible, I would like to reach a 'refresh rate' of 30ms. Packet payloads for data refreshed could be up to 50 bytes...
I noticed that STM32U5G9 MCUs are already available for purchase. That is, STM32U5G9J-DK1, STM32U5G9J-DK2 and several bare bone chips.1) In CubeMX those products are still marked as 'coming soon' but this is the least of the problems.2) The most simp...
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...
