STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on June 09, 2015 at 17:24Hello, I would like to clock RTC with external clocking signal. The problem is, I have 10MHz TTL 0-5V signal at disposal but pins OSC_IN and OSC_OUT have TC pin structure (standart 3.3V I/O). I cannot simply reduce vo...
Posted on February 11, 2014 at 18:18 Hello, Today, we are using a STM32F405VG which is connected through I2S to a PCM interface of a Bluetooth Controller. The STM32F405VG and the Bluetooth Controller exchange audio data through this I2S with audio f...
Posted on June 05, 2015 at 21:16I am a Stm32 new learner.Recently I have had two Stm32 chips to communicated with eachother by using it wardware SPI.After I wrote the master and slave program and downloaded it into both stm32 chips.I used a logic an...
Posted on June 09, 2015 at 13:46Hello,is it possible to generate a interrupt when the pin NRST is activated??I need to reset some variable before the reset of the microcontroller.Thank's!!! #stm32f4-reset-pin
Posted on May 29, 2015 at 12:46I am novice to ST family. I have added DMA1_Stream5 Handler in keil example. When I put breakpoint over there ,it is not executing . Here is my code . int main(void) { GPIO_InitTypeDef GPIO_InitStructu...
Posted on June 09, 2015 at 10:29I discovered this by chance, copying user_functions from an F100 project to the new F030 project. My delay function is based on TIM2 and it works normally on the F030. Is the TIM2 on the F030 or does the compiler chan...
Posted on June 09, 2015 at 10:00I'm getting the following message from my compiler: warning: ''__packed'' redefined [enabled by default] which is defined in the usb_conf.h file from the USB_OTG library, and in the cdefs.h file from the gcc. Any ide...
Posted on May 12, 2015 at 08:35Hello I'm using an STM32F302CB. I use this code to protect the first pages of code which contains a bootloader:[code] uint32_t write_protected = FLASH_OB_GetWRP(); uint32_t protect_mask = OB_WRP_AllPages - BOOTLOADER_W...
Posted on June 09, 2015 at 07:05Hi , I am using chan's FATFS with stm32f4 discovery,, So I could see that two paramateres, &sharpdefine _MAX_SS 512 and &sharpdefine BLOCK_SIZE 512 But when I change it to 4096 the FS is no longe...
Posted on June 09, 2015 at 03:52I'm about at my wit's end with this problem. I am trying to get USB host mode to work on the F407 Discovery board. I am using CubeMX with the USB middleware code -- version 4.8.0. Keil IDE.When I connect a keyboard, I...
