HelloI have a code use CAN2 on a stm32F105 he work fine if the CAN bus have not disturbanceBut if i have to many disturbance for exemple if i make a short circuit bethen CANH and CANL when i remove the short circuit the CAN no restart to send data. I...
问题描述：我电路板上使用的单片机是STM32H750系列，电路板工作正常; 始终使用STLINK工具下载程序; 最近，MCU经常出现无法下载程序的问题。具体现象是STLINK工具弹窗显示“读出保护已激活”。关闭弹窗后，出现“无法连接目标”消息，计算机与MCU失去连接。 我在网上搜索了很多解决方案，但没有一个能够解决它。最后，我不得不用新的MCU替换MCU。 更换后，它工作正常，下载程序没有问题，但下载几次后问题再次出现。我非常苦恼，
I have a B-G431B-ESC1 board connected to a 7-pole BLDC motor controlled for speed. I tried connecting the motor's Hall sensors and running it via MotorPilot 6.2.1, both with a 6-step algorithm and an FOC algorithm, both generated with Workbench 6.2.1...
The Debug Display： Startup Address is not 8000000，but 1FFFxxxx, I Have Checked The BootPin, ResetPin, And JlinkPin, All is Right. Power is also Stable, Generally, when you appear to be awakened when Chip sleep, the appeal will appear. After download...

Where can I get schematics for these 2 dev boards in pdf format. I found a link to the cad resources but they do not contain pdf or any recognizable format. Thanks in advance for your help !!!
I am trying to setup my STM32H725 to use serial RAM in memory mapped mode. The memory I am using is:IS66WVS4M8ALL RAM DatasheetI have used IOC to setup the OCTOSPI1 as a QSPI peripheral and mapped CS IO0/1/2/3 CLK from the uC to the RAM.I have tried ...
Hello everyone.I'm interfacing my STM32F745IET6 (master) with an SPI device.I'm using SPI1 interface running at 50 MHz, I was wondering if there's some "rule of thumb" to calculate time needed (in terms of clock cycles) to write n bits over the bus. ...
