Greetings, I am using STM32-L073RZ nucleo board for the testing of ADC watchdog and sleep mode. I want to keep my instrument in sleep mode and when ADC readings increased by few counts then I want to wake-up my controller. I have written below m...
Hi I have a simple question about DFSDM configuration. I want to apply sinc5 with 32 samples length and therefore get 32 times decimation. Btw, I use internal ADC1/ADC2 in dual mode. STM32H725.Thus, for a given ADC frequency F I expect to get decimat...
Hello,I am new with STM32. We would like to do a current control exactly like on this document :https://www.st.com/resource/en/product_training/STM32G0-Analog-Comparators-COMP.pdfpage 13But we would like to use COMP1 for ZCD and COMP2 for overcurrent...
Hi,I am accessing a DRV8873s motor driver (SPI version) on two different NUCLEO boards. My usage is limited to reading data from 2 registries.I got it to work on a NUCLEO-STM32F411RE using SPI2, with the following settings:Motorola format, 8 bits, MS...
I've been trying to set up a timer and DMA to run a synchronous parallel bus onto a GPIO. The timer works great but the DMA keeps failing with a transaction error interrupt and disables the stream. This is on an STM32F413 chip and using TIM2_CH1 as a...
Hi there, We are having some issues with our STM32H7 when the MCU is heated above approximately 55C. This leads to a fault of some form within the STM32 which prevents it from reading an external flash which the code is being run from. This memory is...
When using HAL_SPI_Transmit_DMA with STM32743, must the transmission data buffer and reception data buffer be placed in D1 RAM?Also, is there a way to dynamically allocate D1 RAM? Rather than declaring an array placed in section("D1"), I would like t...
Hello, New here. I am working with a piece of consumer electronics equipment that uses a STM32F101C8 processor. the customer was doing an update to this unit and in the middle of the update, pulled the USB plug out of his computer bricking the unit. ...
I soldered a new STM32 on the board, it can enter bootloader, but it's under Readout protection(I guess I bought renovated chip), I don't know how to unlock Readout by STM32CubeProgramer, finally, I use STVP and ST-LINK V1 to connect through SWD, and...
I am trying to use stm32flash to program my board over UART. I understand that the board needs to be in boot mode in order for this to be accomplished, so using the STM32CubeProgrammer I have tried setting the resisters appropriately. BOOT_lOCK: set ...
