I have two STM32H743 processors which are connected by USART ports. We have to transmit data between these 2 µPs and have no other ports left (SPI or so) which could be used instead.I initialized the 2 USARTs using STM32CubeMX with the identical sett...
I need to program a large array of STM32F730s from a single master STM32F730. ST seems to have lots of applications notes on using bootloaders to pull code into these devices, and also on using STM-LInk to push code in. But what I need to do is pus...
Hello,I think I tried almost everything. I couldn't find an easy portable way of overriding weak exception handlers when I write my handlers in ASM.If I declare and export function in ASM it is simply ignored and weak one is used. Two ways I found of...
Hello, How to read data from slave in 1 line rxonly. I have this set up STM3f446re board as master and arduino uno as slaveMaster and slave are connected through only 2 lines. MISO and NSS. Master will be in rxonly mode and slave sends data to master...
Posted on June 23, 2018 at 12:13Hi,I'm trying to use the example code from cubeV.10 PWR-?PWR_STOP2_RTC.The only code I added was after the SYSCLKConfig_STOP() function I added Init for LED 2 and turning it ON till the 5 sec delay then OFF...
Hi,asking help for a behaviour that i was not able to find in previous discussions.i'm using for the first time this value line microcontroller :STM32L010K4T6 ,other production details printed on case are GQ20T VG CHN74815.I im using it on an empty P...
HelloI would like to boot my bank 1 or bank 2 card by activating / deactivating the BFB2.I created a program to flash an LED, I put the code in bank 1 at address 0x08000000 by flashing the LED at a certain frequency and then I put the same code but c...
Hello all,I work with the board stm32F746G discoI try to create a master/slave timer. I use the timer3 to master and timer2 in slave.I would like count every second with timer3 and for each trigger on timer3 i would like launch timer2 for a delay of ...
Hello,I am using an STM32L4R5VIT6 board in which I am programming it with Atollic TrueSTUDIO using the debugger and Jlink connectiong. When I am running the debugger, it suddenly stopped working for me and the console reads:Connecting to J-Link... J...
Posted on April 12, 2018 at 20:07Hi to all,I am encountering a problem, concerning the DAC of the stm32L476. I only want to use the DAC with a constant value but with DMA, so that I can use the CPU during that operation. Without DMA the DAC works as...
