So we are checking a solution based on STM32F4 family (in this case) ARM MCU.We have found an Application Note (AN) for the In-Apllication Programming (IAP) for Ethernet, UART and even USB, but nothing for CAN Bus. In the AN there is a statment that ...
Hi,I want to use input capture mode to detect event at every edge (STM32F407 Discovery board).I have toggled the LED (Connected to PD12) using Timer4 Channel (TIM4_CH1) Output compare mode. It's working. The output of LED is given to PD13 to count th...
Hi,Does ST have any Mcu with 32-bit lptimer or 32-bit wakeup timer ?Or there is any plan to do that in near future :)Thanks,
hi I should read the value of the angle of the encoder as5048a via spi, the register has address 0x3fff, a 14-bit register, I tried in several but I failed, can you help me? I use a f401 !! thanks
hello, I am using L031K6 nucleo-32 board.for using low-power-comparator, I want to use VREF for input.before using, I did measure the internal reference Voltage by ADC.L031K6's VREF have internal connection with own ADC VREF channel,so without hardwa...
I'm using STM Cube MX and Keil IDE in order to program my NUCLEO-F334R8 board, the problem is that I have to press the rest button every time I connect the USB port in order to start the main program, What am I configuring wrong? What can I do to fix...
The datasheets for the interface characteristics of each peripheral state "VOS level set to VOS1" which is the 400MHz option. But no information is given on if any of the peripherals derate if you use the slower speed and power VOS options. Would ...
I am working on an existing embedded firmware application on an STM32F746ZG that requires we add one more (9 total) UART. There is an existing ST application note AN4457 based on the STM32F401RE that looks to be a perfect match for my requirements. ...
Hi, I am wondering if there is any possibility to display the variable representation in the table as a character instead of e.g. uint8_t?Perhaps there is some possibility of displaying char strings. This option would be very helpful when working wit...
Hello,I have a general question about the CPU speed an instruction caching. I have worked a lot with 8bit AVR µC that typically run up to 16 MHz. It is always clear how fast an assembler code will run and when which command is executed and how long i...
