we are using the stm32f7508-dk board , we added one function in while and timer 3 interrupt enabled in that code .when debugging the code continuously its going to interrupt , the code in while function executing if i add break points. i f i remov...
I'm trying to debug a problem by which, if the EOT IRQ is enabled, an SPI slave enters an endless loop of ISR executions. I suspect it might be related with how IRQs are generated. According to the H7 user manual: The TXP interrupt is generated whene...
Hello STM32 Team.I using uart1,3,6 setting for baud rate 115200,Uart3 setting is it. huart3.Instance = USART3; huart3.Init.BaudRate = 115200; huart3.Init.WordLength = UART_WORDLENGTH_8B; huart3.Init.StopBits = UART_STOPBITS_1; huart3.Init.Pa...
How to interface Bosch BME688 sensor to stm32f446re via I2C
I tried to overclock STM32G030. I didn't need more speed and such operations should never be used in final product - only for curiosity.But it's 64MHz according to specs. I ended at 160Mhz. Room temperature, 3.3V power supplyTested with rather simple...
Dear all,I am new to STM32 development environment. I recently purchases STM32F407G-DISC1. I also purchased mini USB cable. When I connected the board to the PC, I can see that LD1 is on (RED). I can upgrade the driver for ST-Link as well. So, I am a...
I have spent all day on this. Everything looks good because I can run or debug the firmware from within STM32CubeIDE and it works as would be expected. However, after power cycling, the code is not running.I have checked that my interrupt vector ta...
Hi @, I am trying to configure the display with the H7 series, and the connections are accurate, I've tried more than one LCD to check if the problem is in the display but there is not response from the display side. I wonder if the MIPI DSI initiali...
Hi!I have STM32F469 and I am analysing how to connect an USB port to it.My MCU will act as a device. PC will be the host.My MCU has power supply equal to 3.3V which is created via LDO which is independently powered (not from VBUS, from host’s USB).MC...
本批在测试一款STM32F407VET6，在测试中发现设备授权码丢失的问题。1. 授权码的工作机制设备生产通过软件发授权指令给到设备写入授权码，设备收到该指令后读取 FLASH ID ,然后进行加密，把加密后的数据写入 OTP 区(0x1FFF7800) , 编程成功后读出来验证是否写入成功，如果成功则重新启动，否则返回失败。2、问题分析通过单步调试，FLASH ID 是正确的，但是读出来 OTP 的数据有一部分变为全零了，所以数据比对不通过。
