Hello,i have problem for using STM32H743VI. start from the basic problem, that is transmit UART standard. i use latest firmware of STM32H7 version 1.5.0, latest update STM32CUBEIDE 1.1.0 and latest update STM32CUBEMX 5.3.here the code:int main(void){...

Hi, I am using IIS328DQ with SPI communication. When I Check register WHO_AM_I, it was return 0x64. It is wrong because in datasheet it mention must be 0x32. So what is the solution?Thanks

Thanks guys for the answer..i got the problem. First, yes timing/clock problem. So, i switch manually from HSI to HSE for clock source. little bit tricky, but nice learn. Thank you.

Thank you for the response.i use IC ft232rl for converting UART to USB. and the USB plug into laptop and receive data with software (Realterm and Serial Monitor Arduino). i have done with this method for another STM32 IC like STM32F3 on another proje...

ok you are right.. my fault :Dit solve with CLK Polarity HIGH, phase 2 edge.Thanks..

do you already use this ?The float formatting support is not enabled, check your MCU Settings from "Project Properties > C/C++ Build > Settings > Tool Settings", or add manually "-u _printf_float" in linker flags.

i think my configuration for SPI already match with spec in Datasheet sensor.here my SPI configuration hspi1.Instance = SPI1; hspi1.Init.Mode = SPI_MODE_MASTER; hspi1.Init.Direction = SPI_DIRECTION_2LINES; hspi1.Init.DataSize = SPI_DATASIZE_8BIT; hsp...
