How to convert old code to use FPU ?

Hi I am trying to optimise my gait generation code for my robot. I use a lot of float operations . I want to use FPU to accelerate computing. As an experiment I am using the following taskTickType_t start = xTaskGetTickCount(); while( i<100000000) ...

Would it be possible to calibrate the M48T12 memory using an STM32?

Hello,The M48T12 memory outputs a test signal at 512Hz, with a deviation of 0.001Hz.I tried to read this deviation using a 24MHz sampling logic analyzer, but there was still a fluctuation in the reading of the thousandths of a Hz.I think maybe a 100M...

NOR flash mass erase hangs STM32H753?

Just got a weird problem with a NOR flash, memory mapped on FMC, address 0x60000000.The model is IS29GL128, 16 MB. Most of the code borrowed from eval. board examples.Basically it works (write, read, erase). But during mass erase the systick interrup...

price of STM32H745XIH3 for 200,2K,13K is urgently required

Which guidelines should I trust choosing crystal for oscillator: AN4488 or AN2867?

AN4488 goes like:Why 15 pF is a maximum value? It came out of nowhere. At the same time AN2867:Emmmm...So I am confused. What should I do now? Never use 12.5 pF crystal or use it and do the calculations in accordance with AN2867 to get accurate value...

STM32F4 FLASH MEMORY CHECKSUM SELF CHECKING

Hi, @Community member​ @TDK​ I am working on the STM32F4 to implement the FLASH MEMORY CHECKSUM SELF CHECKING to determine if data and program in FLASH have been corrupted and if so not to run the user program.Any information regarding implementation...
