Hi.This is a really simple question but I don't seem to be able to figure out the problem. I was trying to generate a PWM output (using Timer 2 CH1) on my blue pill board but nothing appears on PA0 after I upload the code.Edit: I am referring to this...
Hi,I'm having a problem that I simply cannot explain so any help is welcomed.I'm trying to flash the G4 via UART, to put it simply the app receives a reflash request via UART then it erases the other bank that isnt being used and writes the new doubl...
Hello,neither in a STM32L0/L4/U5 datasheet I find electrical specifications for the LPTIM unit.At least the maximium external frequency needs to be specified.Regards
I use counting on TIM15 and now need change to 14 , but seems here external pulses counting dont work. FYI STM32F030Is any setup for 14 possible?
Hi everyone First time i read the nand ID with fmc it was all good.It was 0x2c 0xF1 0x80 that the micron told.But some times it couldnt read the id and it was all 0xff.Now when i read the id, i get two different ids.first ox2c 0x1 0x2 0x3 and sometim...
I'm using the NUCLEO-H753ZI dev board and have been testing various tx/rx reception modes using HAL routines with RTOS for all the available uarts. I have them all working well except lpuart1. When I try to receive or transmit in DMA mode I get no in...
I want to make metal detector circuit using STM32 for material shorting specification of circuit is given below.It can detect ferrous and non ferrous both metal.digital out put hi when metal object detected.It can show detected piece area.It is capab...
Hi everyone!I have found that the System Memory (Boot ROM) is always mapped to 0x0000_0000 on the STM32L471RET6 that I'm developing on. The Flash Memory is mapped to 0x0800_0000 as expected but as soon as interrupts are triggered they jump to 0x1FFFF...
HiI want to test the execution speed of SIMD instruction. My demo as below.16-bit addition, for example.I find the instruction __SADD16() in cmsis_gcc.h. The execution time using __SADD16 is 27us and the time without __SADD16 is 23us. It seems like ...
Hi, i'm working with RTC and having issue about getting time. I'm calling HAL_RTC_GetTime function with HAL_RTC_GetDate, it's return old value of time. For example time is 00:10:00 and i called gettime function, it's return 00:09:38. I'm getting time...
