external SRAM
it passes the 16bit test but fails the 32 bit testwhen i check a good board the D1 signal is high not fluctuating.any advice?

Hall Sensor Interfacing Timer
Hello everyone,I'm trying to to use TIM2 as interfacing timer to capture 3 hall sensor inputs. I set the TIMx.CR2.TI1S bit to XOR combination and use OC2REF is sent to TIM1 through TRGO as exactly said in RM0008 Interfacing with Hall sensors section....
SysTick preemt
Is it possible to ensure that the systick is handled (or the timer that handles the ms tick), and at the same time not interrupt higher priorities unless the irq has been busy/active for example 1 ms?I guess the question applies for arm M0 - M4 in ge...
Resolved! How long is __NOP()
Hello,How long does the __NOP() function last?Is it the time of a cycle? Or 1/F = cycle time?My MCU is an STM32F401RE, and I understand that the maximum frequency is 84 Mhz.So 1/84 Mhz = 11.90 ns, is that the time of a cycle?In my case, if I loop 14 ...

STM32L433 goes to hardfault after certen time lapse
Hello everyone, I am using STM32L433 with external crystal 12MHz. SYSCLK is 72MHz. i am using three usarts (1,2and 3). but after certain time period of execution lapse. STM32L433 goes to hardfault handler and executiion stucks, After debug found that...
Resolved! New STM32L431KC does not program or run unless mass erase is performed first.
When first programming a New STM32L431KC, it does not program or run unless mass erase is performed first.I use IAR and STLINK/V2From IAR, I try:a) Download program - uC does not run, even after resetb) Start debugging session - Does not execute code...
What is SAI "Error between selected"? (CubeMX bug?)
Today I spent some time to fine-tune SAI clock to get standard 22.05kHz sample output rate.However, I do not understand why CubeMX states that "Error between selected" is 0.22%.What is "Error between selected"? Why this error is zero when selected fr...
