Hey there.Iam using a L432KC for a simpe periodic SPI communication with another device.when the communication is done the device is sent to sleep.and then the MCU goes into shutdown mode with HAL_PWR_EnterSTANDBYMode();The problem is that the device...
How safe is it to change all JTAG pins to inputs to prevent read out of RAM in protection level 1?I tried it today and I could no longer connect to the board and dump the RAM. But how safe is it?I read about the Nintendo Game & Watch that use an STM3...
Hello Everyone , I'm working on project wich require using vl53l0x Sensor of STM32 B-L475E-IOT01 and i have one issue wich is I Cannot have a PWM signal in output when i'm using vl53l0x senor .I have set a 80 MHz clock and i configured the Timer and...
Hello,I'm trying to establish SPI communication between STM32F4 discovery board with STM32F407 MCU and an Arduino uno. The arduino acts as a master and I'm using it to interface my board(which acts as slave) with the PC since I like arduino uno's ser...
I'm trying to build a double buffer (or ping pong buffer) using the HT (Half transfer) and TC (Transfer complete) interrupts. Also, I'm using DMA with circular array and ADC is triggered by a timer at 6 kHz. I have the algorithm below (I'm not showin...
I was trying to erase some flash pages on an stm32g474re nucleo (and on a custom board with the stm32g474veh3).The flash pages are all on flash bank 2, because i read in the reference manual that flash bank 2 can be written while code is running from...
Hello,I make STM32G473 UART DMA work in debug trace mode (ST-LINK V3).when I disconnect wire and power off to reset for free run.it's not work.I don't understand.
Hi everyone,We are facing issues with USB in our new products due to EMC (electromagnetic compatibility). IEC61000-4-4 burst, mediuum severity.The USB stops working fequently when the device is connected to a PC and a burst is applied to the AC power...
I am not sure how to handle DMA channel from memory to peripheral. I have a circular buffer of 2*24 words that I want to load to PWM. I want to update(generate) new values once half and top of the buffer is reached. I was using similar thing for ADC ...
