Posted on January 06, 2017 at 15:42We use the STM32F100VC for one of our projects. We were able to order devices marked as STM32F100VCTB (Revision A) and the STM32F100VCT (Revision X). Based on the ordering information of the device the letter 'B' s...

Posted on August 26, 2013 at 09:41Hello I tried to migrate a working SPI master from a STMF20x device to the STM32F37x device. The SPI master should write and read 8bit data to some SPI memory devices (EEPROM or flash) by using DMA. Attached is the ...

Posted on March 11, 2013 at 14:13Hi We figured out some ADC channel miss match on STM32F100C8 device, which we couldn't explane. We use the following test setup: - ADC1_IN0 (PA0) to ADC1_IN3 (PA3) are used. - Regular group scan mode with DMA is used...

Thanks for the link and clarification of the topic. I will use the first sector of internal flash bank 2 as a kind of OTP replacement.

Dear UweThis is the reason I am confused about the user options topic. The data sheet talks about 2k user options but the ref manual dosen't as you mentioned.

Hi DanI am also looking for a possibility to use the 2k user option bytes of the stm32h7 devices. But I am not sure if these so called user options bytes could be freely used or not. Did you figure out how the user options bytes could be accessed and...

Posted on February 19, 2018 at 09:44If we decide to fix the issue. I well share it.But first we have to figure out what the best solution would be for us. It seems that the LL for the STM32F1xx devices is a unstable release if a fundamental function...
