I am using a STM32F401RE board and I want a timer interrupt to trigger every minute. I have tried it using timers. Here is my code: main.c TIM_HandleTypeDef htim10; int main(void) { HAL_Init(); SystemClock_Config(); // Some other code MX_...
Hi,I am using DMA to transfer the conversion of two injected channels of the ADC module (registers ADC1_JDR1 & ADC1_JDR2) to a buffer in ram. The conversion is started by software (JSWSTART).Since the transfer is for two consecutive records, I have s...
Hi, i'm trying to measure capacitance using a single GPIO pin ( found an article online a guy used this method to calculate the diode reverse current so i'm guessing its possible to measure capacity aswell). Firstly i use the pin as output and charge...
Can't program STM32F407 because address is not supported for SWD/JTAG port.Hello, I am trying to begin developing drivers for the STM32F407VG. I am using Atollic TrueSTUDIO as IDE. For loading the programs to the board I am using Exteral Tools config...
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...
