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...
Hi, My board consists of stm32f469 that interfaces SDRAM via FMC. I want to execute code from SDRAM. Code is loaded from internal flash to SDRAM at address 0xc0000000. But running the code from this region causes hard-fault. Is there a restriction wi...
* I want to know how to read 2 or more sensors data in (stm32f042g6) through ADC,*stm32f042g6-> This is my controller has only one ADC (with 9 channels),Eg: Suppose Channel No :1 (temp-sensor) Channel No :2 (gas-sensor) connected,*In this scenario ho...
I try implement a function to detect how the MCU start from, reset from watchdog or hardfault or recycle power.Watchdog reset, if the code goes to dead loop, it will trigger WD, but I have no good idea how to capture it.Recycle power, I can use PVD_I...
Hello,I've not much experience with all STM timer modes. I have a DDS-based freq source which produces meander wave. On base of this src I want to produce PWM signal using STM timer. As I understand, a regular way to do it is to pass the DDS src as e...
Hello, the datasheet of STM32F030C8 say to use 100nF and 4,7uF capacitor. I have a doubt about the type of this 4,7uF capacitor. I have to use a ceramic, tantalum ou electrolytic? If I use a ceramic, this need a specific model or any ceramic capacito...
hello all, I try to use the arm lib to make a FFt but I d'ont understand it well and so I can't. I need some help on it.first, I make a acquisition of a signal (form a generator).the signal is at 30KHz. I sample with the STM32 at 1MHz. I use a DMA to...
Hi all:I have an STM32F407 and I am trying to implement a CAN bus software driver.I want to know if there has been a Rx FIFO overrun, which would mean that the firmware is too slow and is not seeing all received messages. Each hardware Rx FIFO can on...
Hello,I am currently utilizing STM32F205xxxx chips on several board designs, but may need to transition to other chips within the STM32F207/15/17 family due to procurement issues. I wanted to confirm the pin-to-pin, hardware, and software compatibili...
Hello,I would like to know the behavior of the BOOT0 pin on a factory fresh STM32G474 device. I'm wondering if I can use PB6 as a general input without causing side effects if the flash option register is at factory defaults. The reference manual sh...
