Posted on July 17, 2017 at 09:17 Hi All, I would like to read a resistive touch screen with a STM32F407 micro butwithout a driver chip. For that I should change the pin functionality at run-time. First I set the configurations like below: ...
Hello everybodyI was trying to store some data into flash and every time the erase page failed, the write completed if the memory was empty.I then found out that the erase is working until I send something over the CAN ( receive seems to not trip it)...
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 ...
