Hi, i came across a program to config alternation function for SPI GPIO port A. GPIOA->CRL |= (11U<<20); // PA5 SCK AF output push pull GPIOA->CRL |= (11U<<28); // PA7 MOSI AF output push pull What does the 11U means? i know its somethin...
I have a project , used regular conversion ADC1 Vrefint Channel and Temperature Channel, and used injected conversion ADC2 extern Channel(ext.CH1 and CH2).ADC2 CH2 connect 2000mV voltage , CH1 is changed. If CH1 over 3.6V,the CH2 conversion is error...
I need to generate a simple CRC16 checksum from a unit8_t array[64] in javascript and validate the checksum on the STM32F373.I have been looking at the CRC unit and all of its options. I see STM32 use a non-standard scheme.Does anyone know of a samp...

Hello everybody,Actually I'm working on a temperature sensor. This project works on battery (2 x 1.5 V alkaline).I would like to read the temperature in the room with an external analog sensor.But I don't understand how VrefIN works. Because my Vcc s...
NOTE: I have edited this post after some of the replies, to fix some typos in the code and to use "insert code" instead of "Preformated" to get syntax highlighting. Hello,I would like to understand what is the recommended approach when working with i...
Hi,i want to store information about the bootloader into the FLASH. Since the size will vary during development, i wonder if its possible to put it before the bootloader.If anyone knows about a good tutorial or video, i would be happy. I dont know wh...
