Facing Timing Issues with Floating Calculation on STM32F103c6 ( Cortex m3)
Hello,I am using STM32F103c6 ( Cortex m3) and there is no Floating point unit on this Board.1: If I am doing floating multiplication, Square root and Division, It takes too much time approx(2-3 micro second and for square root (13 us)).2: I also trie...

How to the STM32F4 Chip action normally. When the LSE clock install fail.
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
STM32F469 SDRAM addressing issue
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...
Performance hit running code on STM32F7 vs SMT32F4
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...
Byte, half-word and word accesses to peripheral registers
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,...
Passing float value to UART buffer ?
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
