In STM32F437 data sheet it says VDDA - VREF+ < 1.2 V.Is that a "global" limitation or just a working limitation?If VDDA is 3.3V and VREF+ is 0V, can that harm the chip, or is it just that the conversions don't work right?
Hi all,I am using the Delay function as follows.static void Delay(volatile int d) { d = d*20; while (d--) asm volatile("NOP"); }However, sometimes when adding printf code, Delay function becomes slow.So, when I analyzed the cause, I was able to...
I'm having trouble making use of SDRAM (external device memory) on the STM32H743 EVAL2 board. Specifically, I'm trying to make use of FMC SDRAM Bank 2 (Region: External Devices) to store a large array. Here are code snippets that I have added/modifi...
Hi, I'm curentlly in the process of switching to a STM32L412 from an STM32F3 on a custom design and I'm having an issue with the UART bootloader. The bootloader worked as intended on the F3 chip but on the L4 chip I can't write to the chip. Everythin...
Posted on March 19, 2017 at 21:42I have the STM32F407 Discovery board running with LWIP. I am able to ping the board and get replies.I now want to get a Web Server running on the board. I used CubeMX and Enabled LWIP_HTTPD on the HTTPD configuration...
Hello. I am developing a custom board with STM32F405. I want it to work as custom HID device. The board must connect to the PC through an already existent driver software. I tested he board with the Keyboard and Custom HID device examples in the pack...
hello,I am using ADC for data acquisition using 46 uSec. I would like to do some calculation every 4 samples. I am using timer to trigger Adc reading. Can I use osMessageQueue in ADC complete conversion call back function to put 4 new adc reading int...
Hi,I have a custom board with STM32F746 MCU and XPT2046 touch controller (Clone of TI TSC2046E). They are connected on SPI2 (no other devices on this bus), running at ~210Kbit/s.I couldn't get the touch controller to work correctly, so I've connected...
I'm developing on Linux and I would like to find a c++ library that simulates the behavior of the stm32 micro controller's family. I'm looking for something similar to simavr. is there something like that?
I am using STM32H750VB for my project. I am unable to configure parameters for MODBUS communication. When I activate Modbus communication using CUBE MX .I have attached the screenshot of the problem and also my cube version. I want to configure the b...
