Posted on March 23, 2017 at 14:12I think that there is dangerous a bug in the cmsis_os implementation, because when you create a queue (thru osMessageCreate), it creates a queue in FreeRTOS with the item size based in the item size configured by the...
Hi, I'm having a doubt related to HSYNC, VSYNC and Porch Calculations. I'm working with STM32F746G Disco Board and wanted to understand how these values are calculated. The HSYNC, VSYNC, HBP, HFP, VBP, VFP values mentioned in data sheet (https://cach...
I got the latest CMSIS from github and tried using the DSP code on a STM32H743ZI chip. I call three APIs which are:arm_cfft_f32()arm_cmplx_mag_f32()arm_max_f32()The code compiles fine with GCC but when it comes time to link I get a 'undefined referen...
It's an expected behavior that Flash could be corrupted if the write operation is interrupted, such as by power loss or reset, as stated in RM0360, RM0444 etc.But there is no information about the distribution of the corruption. Only the data writing...
I want to send 32 bit data and I want to read 16 bit data. How can I make this ?Best
Posted on September 04, 2017 at 16:24Hi, I am using STM32L476 Discovery Board, as part of my project i need to enable USB OTG Port as CD C Class. Could some one help me in fining any example for USB OTG CDC Class for STM32L476 Discovery Board. ...
reading the reference manual of stm32f103, i came to know that ADC prescaler is set using RCC_CFGR in keil.hence in keil xxxxxxxxxxxxxxxxxxx=RCC_CFGR_ADCPRE_DIV2;i dont know what to put at the place of xxxxxxx in Keil ?as in case of stm32f4 i know A...
I have used the dsPIC30 and 33 family of microcontrollers for several years, a pickit 3 for programming the microcontroller, and MPLab. I would like to try the STM32F7 series, but I don't know the best way to begin. My goal would be to have zero of...
Hello everyone,Which of the microcontrollers in STM32 series contains the least silicon erratas, and has the best quality and reliability.Thanks.
for my project I have to perform some controlling functionalities at high update rates (ideally the firmware should update at over 20 Hz)read data from the SD card through a very slow bandwidth with the sd card. the sdio clock is set to a low value d...
