Hi,I'm using an STM32F746ZG and writing my own custom bootloader. The bootloader will work by initially running and determining which of 2 applications to launch, both stored at different locations in the MCU's internal flash memory. How do you pass ...
Hi guys, I tried to setup frequencies for cores to max which is possible. The code for LL was generated, compiled, but the actual frequency of core M7 (480 MHz) looks much lower than 480 MHz. LL generated codevoid SystemClock_Config(void) { LL_FLAS...
Good evening (o;I know that most GPIO pins can be driven from 5V devices...But how about connecting a 5V bus transceiver? Is that also save?Or better to use a level shifter in between?Reason for asking: Project involving SN75160/161 bus transceivers ...
Hello, I have two boards: STM32F74G-DISCO and STM32f407VGT6 They are connected with CAN bus, but the connection is not working. On the picture in attachment is my schema. I think that my code is okay, but I am not sure about schema. I have two transc...
hi, I am working on a stepper motor driver with stm32f407. Facing a challenge in generating exact number of steps for driving the motor. Now what i have done is, i shorted a pwm generating pin with input capture and stops the pwm generation once the ...
Our Security requirement is Device with Secure Boot with Image authentication using Public Key / Certificate. But We could not find any st device which supports asymmetric authentication.
I am working on the Nucleo F429ZI, and I'm working on a dual bank configuration, and I have a function that erases the flash of the other bank and loads in a new user application. I'm wondering if there's an easy way, or available function call, to f...
Hello.I work with STM32L433CC and have the own bootloader that is placed at 0x08000000. It starts and jumps to 0x08002000. There is the main application.It seems that the application works proper. UART Tx with DMA works fine, UART Tx with DMA too and...
Hello everyone,as the title says: Is it possible to use the backup register with an external battery so on power off the data persist. And also use the backup SRAM but on power off the battery should not be used here and all data will be lost.We woul...
Hi guys,Probably the question has been asked one million times but being new on this site, i did not find any clue. My problem is using STM32F446 on SPI1 with DMA2 addressing a device (ADIS16488) in 16bits SPI in mode 3. Polling works perfectly but s...
