I am trying to use the 16 MHz HSI as the clock source for I2C. When I set up the I2C_TIMINGR bits for 100kbps I2C, everything works fine. When I try to set up for 400kbps, it still works, but the timing is not 400kbps. Does the accuracy of the HSI de...
Posted on July 21, 2016 at 20:32 Hi. When I send data out via USB, the program goes to HardFault. I found out that this happens when the function below is executed: USBD_StatusTypeDef USBD_LL_SOF(USBD_HandleTypeDef *pdev) { if(...
I am confused:I have a PCB designed for STMU575 and I am using USB FS - works.USB DM and DP are pins PA11 and PA12.On U575:- all fine as USB FS, available via AF10 (PA11 = OTG_FS_DM, OTG_FS_DM) - worksI have checked the packages and pin assignments a...
Hi Team@ST, 1. can you please point me to the official default image present on the Nucleo-f401RE board. I accidentally deleted the image and i wanted to restore Nucleo-f401RE board to original image. Thanks
Hello,I have a Nucleo board with an STM32F767Zi using its I2C master to test a third party chip that is an I2C slave. Unfortunately the slave occasionally fails (stops sending bits) and the STM32 master driver does not recover, it needs a hard reset ...
Hi there,I recently transitioned my project from the STM32L0CBT6 chip, which has a 128KB flash size, to the STM32L072CZ variant with 192KB of flash memory. As I progressed with my project, the only modification I made was adjusting the flash memory r...
With DCMI (with DMA) and USART only 1.5FPS, why is the frame rate really low? The output is set to QVGA and formatted as JPEG.
Hello everyone,I am working with the STM32G0B1KEU6 microcontroller, which comes in a 32-pin package featuring only ports A, B, and C. According to AN2606, the internal bootloader uses the following pins:FDCAN1_Rx pin: Input PD0, used in alternate pus...
Hello Everyone,Problem: I am working with a instrument where we frequently get the problem of frequency drop out, i.e. suddenly frequency signal goes missing i.e. goes to zero, this cause the loss in data as shown in the below image. Yellow is receiv...
