Is there (or have there been) some big issues with the BFB2 option and the STM32 Bootloader ?I have been trying to implement firmware updating from our host by using the BFB2 option bit on three different STM32's and all of them behave differently:ST...

Hi,I have DMA2D (ChromArt) working fine for drawing images from memory to display buffer.However, to save on image storage, I would like to create single pixel image "strips" which I can repeat a number of times in X or Y.eg, for drawing a top border...

Posted on June 27, 2018 at 16:46Hi,We're just completing a design based on the ST BlueTooth Low Energy module SPBTLE-RF.However, we are finding it very difficult to find any stock (in the UK at least)SPBTLE-RF is marked as not recommended for new de...

Posted on December 15, 2016 at 16:04I'm trying to get I2C to work in DMA mode from STM32Cube_FW_F7_V1.5.1My first error was that the I2C handle remains busy after the first DMA transfer is complete.I've looked at the procedure I2C_DMAMasterTransmit...

I eventually found that changing bDeviceClass and bDeviceSubClass in usbd_desc.c to 0x02 will let the Native Windows 10 driver see the device as a COM port. We must have been using an old example (CDC_standalone) as the latest STM32Cube FW examples a...

We changed the design once already and picked a less popular STM32, one with stock everywhere (at the time) and bought enough until mid 2022.Looks like it probably wasn't enough but what were we supposed to do ? Buy everything we could find and make ...

Hi,Looks like your "worst possible scenario" is upon us now (December 2021)We've spent the last year designing two solutions around the STM32L496,STM32F469 and L6470 stepper driver - all are out of stock and at least 6 month lead times now. (Stock of...

Hi,Many thanks for the answer.You are correct, the L476 does not reset if I remove the call to HAL_FLASH_OB_Launch()I think the comment from the example code maybe a bit misleading here as the BFB2 option change is remembered after a hard reset witho...

Good comments and I agree. How did it get so complicated ? Someone thoughtfully created the Bfb2 option bit and the clue is there in the name: Boot From Bank2 If it's set, run code from bank 2 after next reset If it isn't set, run code from ban...

Can DMA2D do a repeat buffer copy/fill from image ?

Re: STM32F078 USB connection to Windows 10 reports there are no compatible drivers. The STM website says " Starting from Windows® 10, the STSW-STM32102 driver is no more adequate and the usage of the native inbox driver is recommended.
