I want to set up the interrupt for system power off the main MCU, the STM32L4 xx .As soon it is powered on, then starting the timer to turn it off after 2- to- 4 Hours.Please point me how to implement it since I'm still new for STM32L4xx
I want to use Nucleo-L476RG to generate pwm output. but the problem is i can't use TIM2. TIM5 is ok. i use PA1 to generate pwm, when set PA1 as TIM2 CH2, it doesn't work. but when i use it as TIM5 CH2. it works. How can this be happened? is there any...
Hello, I am trying to configue SDADC1 and SDADC2 in injected mode to read simultaneous values on the 2 converters. Using CUBEMX I configure injected mode for SDADC1 and sync mode for SDADC2 . Problem SDACD2 always read 0.Any working example available...
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...
