STM32G070 as the alternative to STM32G081
ST has confirmed that STM32G070 uses same silicon as STM32G081, thus we're considering use it as the alternative to STM32G081 due to availability problems.STM32G070 lacks BOR feature and CEC hw block acc. to datasheet but we have proven by trial that...
spi in STM32H7
SPI in stm32h7 (stm32h743iitx in slave mode) don't work, receive wrong values.how I make spi to work correctly in stm32H7? its not clear at allthanks,
Are there any errors associated with the CAN Controller on the STM32F205ZGT6 MCU which could explain the CAN bus packet failures when the ambient temperature is increased to 40°C?
Hi,I wonder if you can help us? In one of our projects we are using the STM32F205ZGT6 Microcontroller and specifically we are using the CAN bus. The problem is that when we increase the ambient temperature around the MCU to approximately 38°C to 40°C...
Resolved! STM32L011K4T6 Wake Up Pin Configuration
I've struggled with this for a few days and read a dozen forum posts that end unanswered.I am trying to put my micro controller into standby mode and then wake it up with an IMU pulling the PA0/SYS_WKUP1 pin high. What I am finding, which is somewhat...
Resolved! WWDG_IRQHandler called after a blx instruction
Hi all,I'm trying to use a version of the elua interpreter on a stm32f446re nucleo board.I've encountered a problem, the program is jumping on an infinite loop after entering a couple of functions of the interpreter. The system is blocking in an WWDG...
stm32h725 injected ADC with timer 8
Hey all, I'm trying to trigger an ADC interrupt with timer 3 on the regular channel and timer 8 on an injected channel for both ADC 1 and 2 on the STM32H725, However, It seems like I'm only ever able to trigger the regular channel interrupt with time...
Trouble with FDCAN
Hello, I built a small CAN network using CAN 2.0 transceivers. I wanted to add some FDCAN devices using classic mode. However, I seem to be having trouble just talking to the transceivers. For instance, I have an STM32L432 (Attached to a Nucleo). ...
Is the MCU STM32H743IIT6 can enable 35 GPIOs at the same time?
Hi,I have designed a STM32H743IIT6 based board for controlling 35 optocouplers(4N35). These optocouplers should work at the same time(worst case). Each optocoupler will take nearly 10mA current. But I have seen in the datasheet as "Total output curre...
