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...
ALL HI�?I am currently using the RTC function of STM32F103, the external passive 32.768KHz crystal and 20p matching capacitor.The RTC function is configured on the software program, and the RTC has been started. But I can't see 32.768KHz waveform whe...
I understand that any external interrupt on PA13, PB13, PC13, PD14 .. or PI15 will all execute the same ISR:EXTI15_10_IRQHandler(void) { HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_13); } Which calls HAL_GPIO_EXTI_IRQHandler before finally calling th...
Hello,we build a breadboard configuration with 20 LEDs. The LEDs have a current consumption of 20mA per LED. It worked properly. Now I read in the datasheet something about a maximum injection current of 25mA of all I/Os (screenshot is attached). So ...
Hi,Recently I started working on stm32 microcontroller. I am trying to write/read data from Flash memory of stm32f070cb.I have tried writing as well as reading data from internal flash memory using stm32f072 disco evaluation board and it is working f...
I once again checked at Digikey and they had only one of those. Will the rest of them ever come backI would to like have STM32H76x 144 pin lgfp, but it is of no use if there are none available when I finish my PCB.
Hello everyone,this is my first post here, please my apologies if I mistake some terms since we jumped into the ST controller world in the company around 6 months ago and I am still learning about the technologies.I have been working so far on a proj...
Hi all,As stated above, I can't seem to wake up the controller from STOP2 mode using WFE with the ALARM A. Here's my alarm and EXTI settings:if(EXTI->PR1 & EXTI_PR1_PIF18) { EXTI->PR1 |= EXTI_PR1_PIF18; ///< Clear pending interrupt if necessary } EX...
I am developing an application for a STM32L412CB and use the comparator COMP1. I designed my pinout with CubeMX and put the output of the comparator on PB0. I also checked table 14 in the Datasheet Rev.8 on page 58, if it is correct. Now I wanted to ...
