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...
I'm struggling to get what I think is not too complex an app running on a Nucleo-H7A3ZI-Q board and could use some help. Eventually I'd like to build up to an app that 1) reads a GPS over the UART, 2) writes the data to a uSD card and 3) uses a time...
I'm interfacing a camera module (OV2640) with STM32F446RE. I've found a driver on github for this camera however the given example from the github repository is for an F7 chip. I've integrated all the files for my f446re chip and everything runs corr...
If I understand correctly, the answer is YES (cannot support level triggered interrupts), only rising/falling edges. If there is an alternate method (read HACK), I'd be interested to hear it.Thanks in advance.John W.
I am using an STM32H743ZI processor and I am confused by an ambiguity in the manual (RM0433). On page 152, the lower table shows two banks of System Flash, bank 1 is 0x1FF00000-0x1FF1FFFF and bank 2 is 0x1FF40000-0x1FF5FFFF. Only bank 1 is marked as ...
How can I make PC 13 blink at a time I set using any timer in stm32f103 using interrupt (without hal library) ?
I have compiled some code on the mbed online compiler and copied the binary code onto the mbed Nucleo64 F401RE board. The LED on the ST_Link board starts blinking for a few seconds, and then the binary file disappears from the USB drive. I assume tha...
I have to write code to write/read to/from an ATMEL 24C256 EEPROM which has a 7-bit address and the eighth bit is for R/W. I guess the MCU should be configured for 7-bit addressing (ADD10 = 0) but in this case how does the MCU write the eighth (R/W)...
Hi, I wonder which one is better for Timer setup:lower prescaler (PSC) value and higher period (ARR) value?lower period (ARR) value and higher prescaler (PSC) value?
hello dear forum,my 103c8 blue pill doesnot enter TIM1 CC interrupt although there is square wave at A8 pinthe variable which I increment inside interrupt routine doesnot count I can see TIM1 counting in CubeIDE I am missing something but I cant f...
Hi,What happens if I write them out of range channel numbers in the ADC sequence register.For STM32L475, the channel range is 0 -18 but I wrote the channel number 19. While debugging, from debug window I found that the seq. register accepting number ...
