Hi Im using the stm32L4 , and if not coming out of standby mode I update the time variables. And all works as expected, It goes into standby mode using the following after a period of time. "HAL_PWREx_EnableSRAM2ContentRetention();HAL_PWR_EnterSTAN...
Posted on April 20, 2016 at 18:24This is a maybe stupid question but I cannot find a good (for me) explaination of how to use them. What the acronym is meant for?I see in the docs'The peripheral initialization is done through HAL_PPP_Init() while th...
Hello, I had a general inquiry about using SPI. We are trying to use the STM32F446xC as the microcontroller to control a SPI-to-CAN controller (TCAN4550) which does 32 bit transfers. The microcontroller can only perform 8 or 16 bit transfers through ...
Hello,I am trying to generate a complementary PWM with a timer in my STM32H723VGTx, I configured channel 1 on timer 1 with the PWM Generation CH1 CH1N mode.I set all the parameters of the base timer and the value for the pulse of PWM, but during the ...
HiAssume that i set up an H-bridge and and control it via the HRTIM block and use the build in deadtime features. I then also enable a couple of faults. The bridges safe state will be to set both lower transistors to be OFF and the two upper once to ...
I am using LPTIM1 of an STM32WB55 to read the outputs of a quadrature encoder.If I disconnect either of the two inputs, the timer continues to increment or decrement.Is there any way to stop the counter changing value when one of the in puts is missi...
Hi,Currently I am working on a stm32 & LTC4015 based smart charger project. When I followed the data sheet the smbus or i2c read & write operation is given as below:-SMBus WRITE WORD PROTOCOL:-S SLAVE ADDRESS Wr A COMMAND CODE A DATA BYTE LOW A DATA...
I am using SPI 1 on a pair of Nucleo-G474RE boards that are running the same software image. On of the interfaces is working correctly, the other is not. A logic analyser shows the following: Working Not working From this, it looks as if there is a...
Hi currently I am implementing a smart battery charger using stm32 & ltc4015.But i could not understand how to perfectly configure ltc4015 through i2c protocol.So could you please inform me how to write the i2c sequences to safely charge the battery....
STM32H5x3 / VQFN68 packageHas USART3 but AN2606 lists using PD8/PD9 that this package does not have.AN2606 has a lot of remapping mentions for specific packages. Is this one of them, or does USART3 and bootloader not work for this package?
