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...
Resolved! Error in Datasheet Rev.8 of STM32L412CB?
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 ...
STM32H7 vs STM32MP1 for heterogenous application use case
For one of the heterogenous application use case, we would like run always-on code in Cortex-M4 and high end application, we have two options. either run Cortex-M7 if se select STM32H7 device or Cortex-A7 if select STM32MP1 device. Assuming that both...
Write to external SRAM in four #WE cycles.
Hello!To MCU STM32h743 connected 16-bit SDRAM and 16-bit SRAM. Writin to SRAM uses four #WE cycles in conjunction with BLS0 and BLS1. When write 8 or 16 bits BLS# active only for one #WE cycle, when 32 bits - two cycle and four cycle for 64 bits. I c...
