I am using STM32H743Bit6.#define GPIO_SPEED_FREQ_LOW (0x00000000U) /*!< Low speed */#define GPIO_SPEED_FREQ_MEDIUM (0x00000001U) /*!< Medium speed */#define GPIO_SPEED_FREQ_HIGH (0x00000002U) /*!< Fast speed */#define GPIO_SPEED_FREQ_VER...
I'm working on a project with an STM32L4 microcontroller and I need to implement an anti-tampering function to detect if the case has been opened using a switch. I know that the STM32L4 has an anti-tampering function on pin PA0, but I'm already using...
I do have time working but it will reset each time when I power it off. I do have the backup battery connected.I thought that it is supposed to keep working on battery and I guess it does. But I guess I might be missing a few lines to read registers ...
I am working on STM32F401RE, transmitting data via UART using DMA 1(channel 6) , also i want to receive data using DMA 1 (channel 5). I want to use the DMA in single byte transfers in direct mode. Can you help me how to do so correctly because i trie...
I am developing a project to take some measurements with ADC channels, however the values are wrong. When I connect any ADC channel direct to GND, it gives me a value about 60~80 (The ADCs are 12-bit precision) and this error propagates for any readi...
I cant find a product finder on the site. With google i cant only find apps. Anyone knows where it is? Mouser is not help either. I would like to look for uC with CAN bus.
I have the following function to sum 32 16bit signed integers as optimally as I think is possible:int16_t sum32elements2(int16_t vals[]) { uint32_t s1 = __SADD16(*(uint32_t*)&vals[0], *(uint32_t*)&vals[2]); uint32_t s2 = __SADD16(*(uint32_t*)&val...
