Posted on December 08, 2016 at 20:29Hi,In the scheduling system we use we need a simple 32kHz low power counter value. Exactly like in the stm32F1 family is present.But in any other family, the RTC registers are replaced by Time and Date registers.I...
Posted on December 21, 2017 at 07:47Dear all i want to wakeup stm32l4 in every two minute from stop2 mode using RTC,give me suggestion.I am using example code from st and trying PWR_STOP2_RTC on my custom board,i am finding that l4 is not going in ...
Posted on December 21, 2017 at 14:25Good morning. I'v tried to perform an UART receive on stm32f407vg board using RXNE interrupt. But when i execute the code it is blocked on WWDG_IRQHandler infinite loop. I post my code:#include 'stm32f4xx.h'#inclu...
Posted on December 19, 2017 at 05:50Hello,I am using the Mikro Pro C IDE to write a simple program to toggle GPIOA pin 0 on a STM32F407VGT6. When I compile I get several errors, but I don't think it has to do with an error in my code, more or less a...

Posted on December 21, 2017 at 12:46Hello,We are using STM32F030 in our project. We are using RS485 half duplex communication for interaction with other boards in our system. Using the same half duplex communication channel, we would like to update ...
Posted on December 20, 2017 at 13:27STM32F030.I am transmitting multiple words via spi to some shift registers and need to latch the shift registers when the transmission of the last word is finished. The latch signal is GPIO. Device is master.I don...
Posted on December 21, 2017 at 09:19For a long time I have been working with stm32f4 discovery board MB997C on my computer without problems. In fact, I've been running 2 boards simultaneously on my PC and it has worked great with both STM32 ST-LINK ...
Posted on December 20, 2017 at 04:45For Motor controller design using FOC sensorless prototype, there are 3 B-EMF signals need to be monitored by MCU. So I shall config 3 ADC channels for this purpose. But with ST MC WB there is no way to do this. w...
Posted on December 20, 2017 at 11:17Hey guys, I'm trying to do something that might be really a noobish thing (will ask in a different thread, and I recognize that there's a strange thing happening. I'm using an STM32 Nucleo64 L073RZI am trying to s...
