Dear Members,How can I get exactly 1Hz interrupt from TIM3 ?I use STM32F4 Discovery and looking at TIM_TimeBase Example, but I can not get exactly 1Hz yet...ThanksCode :TIM_OCInitTypeDef TIM_OCInitStructure; __IO uint16_t CCR1_Val = 54618; __IO uint...
HiI am working on Redesign project. The existing controller is STR912FAWx. In this controller, CAN protocol has CAN_IDR register to identify the message objects causing the interrupt.Similarly, in STM32F4 do we have CAN message object to identify the...
Hello, I'm using STM32F7.I want to save data on F7 memory, where is not delete after reset. My data may has 1-2KB size.Anyone can tell me how to do that?I read and found that i can do with no init ram, but I can not find any tutorial or documents rel...
I was going to use the following code to protect the code for STM32F103, but functions that write OB (Option Byte) are not defined in the SPL structure.
I am using STM32H7 for about 2 years with stable HW an SW .after some SW change I found strange behavior .If the debugger is connected and I flash the application using ICD "ST-Link Ver3" the micro-controller boot normally.but the micro-controller ha...
I have a STEVAL STWINCSV1 board with an STM32L4R9 chip connected to my computer via USB. I am trying to use OpenOCD to flash a new image. I am using the command `openocd -d -f board/stm32l4discovery.cfg` to try to open a connection to the board. Here...
Dear All,Board: Nucleo - H745ZI-QWhat am I trying to do ?I am using to measure pulse width of an signal using input capture mode of timer 2 channel 1. Then multiply that width by two and wait for that much time and generate an output pulse using outp...
Hello,there's a user button on that board. I'd like to attach this button to an interrupt handler.I have to enable this button for interrupts. It should be done by setting some bit in some register called SETENA0 or maybe SETENA1 or something like th...
For STM32F103 part, please advise whether COO Taiwan have different body marking and without "ARM".
Hello,i'm trying to use UART with STM32F767ZI Nucleo board. I'm using the following simple code (the essential parts):/* USER CODE BEGIN PV */ uint8_t a[] = {0x81, 0x00, 0x00, 0x00, 0x00}; uint8_t b[] = {0x00, 0x00, 0x00, 0x00, 0x00}; uint8_t error[]...
