I tried to read through datasheets and STM32F0 programming manuals, but can't find any of clue. I do understand that the STM32F0 is been used in low power and cost sensitive environment, usually not come with huge RAM. If ever huge RAM needed, the el...
PWM channel 01 controls Mosfet 1, PWM 02 - Mosfet 2. Also I need to insert dead time (dt) between channel switches. My MCU has HRTIM. Is there any way to solve this task using HRTIM? If it possible, what is the best way to reduce IRQ count to reach ...
As discussed here, export restrictions because of encryption hardware impose much effort procuring STM32F730 and STM32H750. The question came up several times about possible STM32F720 and STM32H740 variants, but I did not see any comment from ST.
Hello, all!A quick question: if I want to transfer data between 2 STM32 devices, which are located 1 meter apart, at a rate of at least 20Mb/s, in bursts of 300KB at a time. what is the best way to do so?The communication is unidirectional.I suppose ...
I want port U-Boot to my own board with stm23f767;Now I stock with FMC Nand Flash driver;there is a MT29F4G08ABADA on my board;when i set FMC nand register,i think this will be ok;but i'm wrong;i still could not get the nand id;when i debug under U-B...
I have not tried, I would need this 'feature':Have a GPIO pin configured as Open Drain output, driven by the MCU. If MCU sets it to high but on the outside an external chip drives it low - could I read the status on the external pin without to change...
STM32F722 Strange GPIO problem with Multiple CD4094(Serial to Parallel Converter)Hi,I am working with GPIO LED , LCD 4-bit Mode Working fine. But 16 Multiple CD4094 have strange problem as below.I am Just using D0, CLK , STB. and Not using any extern...
Hello to everyone,I'm working on the STM32F746NG Discovery Board to realize a simple audio effect and i need to use the audio codec WM8994. It is interfaced with the SAI2 audio peripheral. I dont want to use the HAL libraries but to write directly th...
I want to connect the PF1-OSC_OUT pin to another circuit on my board, to use this 32.768kHz clock for another counter. ( instead of adding another crystal )Would this be a problem? I can buffer it to minimize pulling the crystal. Any suggestions?(I...
I am using #[STM32 MCUs] #Cortex-m0 . In linker file we have symbol: __ICFEDIT_region_ROM_start__ How we can use this symbol in application ?I have assigned &__ICFEDIT_region_ROM_start__ to Pointer.i.e int *p = &__ICFEDIT_region_ROM_start__now usin...
