I am working with STM32F405, I seem that the SMT32F405 had hanging when the LSE clock install fail in SystemClock_Config function. So, is there any way, when the LSE clock config fail but the chip still active normal. Thanks
I am experiencing an issue using STM32F469I-DISCOVERY board, Atollic TrueSTUDIO and STM32CUBEMX. When writing to a memory address in SDRAM, let's say I'm writing 0xAA in memory address 0xC0000004, the data is not written to that address but instead i...
Hi,I'm currently implementing an encoder/decoder for a Forward Error Correcting code (specifically a Fountain Code) that I'm trying to implement on an embedded system and optimize for speed. I'm currently using an STM32F429I-Discovery Board as well a...
I am reading the STM32Lxxxx Reference manual (RM0394 Rev 4, October 2018, DM00151940).On page 267, section 8.4 "GPIO registers" says "The peripheral registers can be written in word, half word or byte mode." Sure enough, any access works.On page 308,...
Dear Members,How can I pass float value from RPM to UART bufferfloat ==> (uint8_t*)&aTxBuffer8 ?(uint8_t*)&aTxBuffer8 = snprintf(str_rpm,sizeof(str_rpm),"%f",rpm);?Thanks
i need to interface 64GB memory card with stm32f446ve controller,its file format is exFAT,is stm32f446ve supports 64GB?which interface is to use SPI/SDIO ?Thanks
I'm testing printf() out on USART1 and UART5 of STM32F3DISCOVERY Board.USART1 tx (PC4) <-> RS232C converter UART5 Tx (PC12) <-> RS232C converterprintf() out on USART1 is working normally. but, printf() out on UART5 is not working.Could you please che...
