Dear experts,i try to use the float library with printf or vsnprintf. The option nano has been checked, the -u _printf_float too. The latest version of STM32cubeIDE, the proc is STM32F446RE. The value of floats are correctly displayed in debug but i...
I want to learn that Can we use 4x I2C communication protocol in STM32F407?
Hello,STM32F74xxx Reference manual (RM0385) 6.3.2 I / O pin alternate function multiplexer and mapping has the following description.After reset the multiplexer selection is alternate function 0 (AF0).I think that when AF0 is selected, it will be ass...
Hello everyone,I am currently working with the STM32G474QET6.Trying to measure Honeywell pressure sensors whose output voltage ranges from 0V to 3V.The problem is that the measurements have a much greater error than indicated in the data sheet.To rul...
Hi,I have a circuit board that uses STM32F401CEU6, and now I decided to replace it with STM32L433CCT6.I want to know the transplantation method from using STM32F401CEU6 to using STM32L433CCT6 in the program.Regards,Zhao
