The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi,I have a STM32L476RG board and I try to execute the following program, obtained from this web http://www.microdigitaled.com/ARM/STM_ARM/Code/Ver1/Chapter02/Program2-1.txt which is for a different Nucleo 64 board (STM32F446RE)/* p2_5.c Toggle Green...
Hello, I am attempting to transmit a simple CAN message between two STM32F469I discovery boards. I am using the official STM32F4 github as reference found here: https://github.com/STMicroelectronics/STM32CubeF4/tree/master/Projects/STM324x9I_EVAL/Exa...
I am new to ARM processor and I need to know what are the header files required in main.c for programming the above MCU in C by just accessing its registers (and manipulating bits) as explained in RM0390 (REFERENCE MANUAL for STM32F446xx) ?NOTE: I am...
Posted on July 02, 2018 at 11:00Hello,I am using an STM32F042 controller. I have to send a wake-up pattern followed immediately by 5 bytes (@10400 baud) from my device. Wakeup pattern: 25msec LOW followed by 25msec HIGH5 byte sequence: 0xC1, 0x11, 0...
Dear all,for my application I need to store some user settings in the internal Flash and be able to modify/read them during execution. I have been succesfully familiarising with the Erase/write ans read functions with no particular struggle. Now I wa...

While preparing slides for students about timers in STM32F7 microcontrollers, I came across several inaccuracies in the description of their work presented in the STM32F7 reference manual RM0410 rev 4. The following sentence can be found in the menti...
I have been told that the STM32F103C8T6 has 4 SPI peripherals, including the 2 SPI peripherals and the USART peripherals. Though upon browsing the reference manual in the USART section, it seems as if it has to use start/stop bits, and therefore can'...
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...
