In RM0008 Technical Reference Chapter 15, TIMx_ARR was introduced in counting mode. Meanwhile, two other registers: preloaded and shadow register, were also mentioned. However, in the TIMx register Map, Preloaded and shadow registers were not mention...
I'm trying to perform signal filtering with STM32F407VGT. I've set up the ADC and DAC to work synchronously, triggered by a timer at 42kHz, and using DMA. The idea is to process half of the buffer while ADC is filling the other half. However, even wi...
In the RM0008, Figure 120 on page 379, it says "as soon as the CEN bit is written to 1, the prescaler is clocked by the internal clock, CK_INT. " as shown below. However in the figure, the CK_CNT appears 2 cycles after the CEN bit became 1. Given t...
Could anybody help me to figure out the exact meaning of PWREN bit in register RCC_APB1ENR?I could not find any comments in the STM32 programming reference mannual.Thanks,Troy
HiI'm trying to create a bootloader for STM32F746G-Discoboard firt before create my own board. I have read AN2606 and AN3155 to create it by UART but also found this https://github.com/ferenc-nemeth/stm32-bootloader. I'm a little confused about what ...
Hican you please check the stm32h743_753_lqfp100.ibs model from the en.stm32h7_ibis.zip archive? I have a problems simulating SI on the rmii interface, most likely because of this output model: io8_i2c_ft.Right now there is only two ic with direct rm...

i want to use timer in one pulse mode is there any sample code for TIMER OPM mode.
I'm working on a course and until now all my examples worked fine using HSI as the system clock. But now I'm trying to get an ST7735 screen attached to SPI to work. The screen screen seems to require its hexadecimal instructions bitwise and the param...
Hi, I would like to know how to flash a program to my STM32L053 Nucleo board, for now after each power cycle I need to download the program via a debugger to the board, is how do I flash the program to the board ?
