Has anyone ever gotten DMA2 to update TIM1 or TIM8 CCRx registers to work ?

I've been trying to get any DMA2 stream-channel (presently TIM1_UP) to update TIM1 CCR1,2, or 3 registers using a table in memory for a while now with no luck. Before adding some of my code here, I thought I would see if anyone has ever actually gott...

STM USB VID and PID in commercial products

We are developing some devices which will use the usb as a virtual serial port to mainly update our devices with our own bootloader. Do we then need an own vid and pid for usb? Or is it also possible to get and use the vid and pid by STM?

I2C in Interrupt Mode stays in HAL_I2C_STATE_BUSY_TX even if the data is correct transmitted

Hi all,I do have a problem with the Interrupt Mode of the I2C interface. I started with the example provided by STM (I2C_TwoBoards_ComIT). I do not use two boards but one board as slave and the master is an FTDI FT4222. So sending from the FT4222 to ...

What to do if an LPTIM takes too long to wake up STM32L476 from Stop 2 mode for the first time after every reset when LPTIM1 is used as a Timeout wakeup unit?

I am using STM32L476.I want to enter the Stop 2 mode and use LPTIM1 as a Timeout wakeup unit.The code is written such that the LPTIM1 wakes up the MCU from Stop 2 mode after every second. The LPTIM1 takes too long to wakeup the MCU for the first time...

lin software on STM32F103 - Detecting stop bit errors

I develop an own LIN slave node software stack for the STM32F103RB. This stack has to pass all tests from the LIN Conformance Test (according to ISO 17987-6). This test is a customer requirement.Actually the software and/or the hardware could not det...
