Hi, I am working on a realtime audio DSP product using the STM32H7 with a AS4C4M16SA-7BCN SDRAM chip for long delay line memory. I am using the FMC controller with the settings in the attached photo:The product processes an incoming audio stream in r...
Hi,I need to generate ~8khz PWM on 40 pins with at least 1% resolution. I was thinking about solution using GPIO ports D,G,F and DMA2 streams 1,2, 7 which are all triggered by TIM8 (TIM8_UP, TIM8_CH1, TIM8_CH4/TRIG/COM).I am worried about the data tr...
I am use nucleo-h503rb evk board and i am configure fdcan communication. I have mention below my code please see. I have did not comes output on FDCAN communication. please send me demo code for that
Hello, I am using your STM32F103RET7 series.We need the functionality of RDP Level 2.Once you write, you have to implement something that can't enter and erase.Is that function possible on this chip?First of all, we are also reviewing STM32F205RGT7 c...
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...
