Hello all,I've been working on and off with the timers on the STM32F7 and I've noticed a few inconsistencies, though it may well be me not setting something right.I'm using:STM32CubeMX 4.27STM32 WorkbenchFirmware 1.12 for F7STM32F767ZIGetting the tim...
I'm running v1.26.1 of CubeMX and any code that I add between the /* USER CODE BEGIN.. and /* USER CODE END.. comments gets deleted every time I (re)generate the project. I have the 'Keep User Code when re-generating' option ticked. What am I missi...
Hello,I'm working on a product where we will use the STM32L71 device containing an I2C Interface for servicing and control. I develop first parts of the firmware on a STM32L53 nucleo board. Since the device must be hot-pluggable, it is not allowed to...
I'm trying to set Timer 2 (32 Bits) from Nucleo L432KC to measure input signals up to 1 kHz (for example). However, I'm confused about the selection of the prescaler and counter period. I read in a book:Another relevant condition is that the UEV freq...
I want to use a 8MHz quartz for an STM32F765ZG, i want to know some quartz' references with passive components needed.
Hello,I've had some trouble using the i2c interface on my Nucleo F722ZE board. I try to achive constant rate data sampling from my MPU6050 IMU. (accelerometer+gyroscope)For this I use the following 1000 Hz timer interrupt routine:void HAL_TIM_PeriodE...
Hello, I would like to use an external supply (3.3V) for my nucleo. the user manual tells me that I have to connect PIN 12 (IOREF) to +3.3V and also the PIN 16 to +3.3V. Both pins from CN7. Is this correct?And also GND to external GND. I already remo...
I WANT TO USE GSM MODULE WITH STM32 MICORCONTROLLER . IS GSM AT COMMAND SET LIBRARY AVAILABLE?IF YES, PLEASE SHARE THE LINK OF THAT LIBRARY.
Hellow, I've been dealing with this problem:I run the UART-printf example on my STM32L011T6 board and it works perfectly. But when I start a new project in System Workbench, name it however I like, add a Hardware Abstraction Layer (HAL) as a static e...
Hi, I recently got the STM32F7691-DISCO Board and have tried to follow the you tube video athttps://www.youtube.com/watch?v=u2Zu5G0PHx8From the files download I have two files in the binary folder, X-CUBE-VS4A-LWIP_esp-v1.1.1 and X-CUBE-VS4A-LWIP_et...
