Posted on September 25, 2016 at 10:27Hi.I have to reduce system clock from 72 MHz to 48 MHz. Input frequency is 16 MHz from external oscillator. I could achieve 48 MHz in two ways:1. With PLL PREDIV = 2 and PLL MUL = 6 or2. with PLL PREDIV = 1 and P...
Posted on September 24, 2016 at 14:58I have several stm32f746g disco mb1191b-02, and they are beautiful!I recently purchased stm32f746g disco mb1191b -04, but for my application slows down a hundred times. Keil compiler. How to make it work fast?
Posted on September 24, 2016 at 17:57 Am trying to run USART by getting to write in the E-Terminal of CodeLite to interract with my STM32F4 However, i get no response when i the main method is called....here is my main method.... #i...
Posted on September 24, 2016 at 11:37hiI'm using nuclei-f446re and LoRA communication module.recently, i tried to send 0x00(null).but i can't.so i tried all all code send using LoRA comm module to another module. The result was not successful.Not se...
Posted on April 07, 2014 at 12:39 Hi. I successfully configured my STM32F103VC custom HW to use a rotary encoder by following the code suggested in this forum. So first of all: thank you! When I wrote ''successfully'' I mean that the cou...
Posted on September 11, 2016 at 16:41I am experimenting with FreeRTOS and the HAL layer using an STM32F4 DISCO board.I have two threads. One reads from the serial port and send the byte read, in a message to a second task.The second task, blocking ...
Posted on September 24, 2016 at 01:37Hi there,I got an issue recently when I was trying to set up the I2C speeds for STM32L476RG. I can set it up for an approximate value but never get the exact one. For example, I want to achieve 100 kHz while I ca...
Posted on September 24, 2016 at 00:16I am building a testboard with a 100pin 407VGT in it. There is no room for USB on it. After reading the HW manual I still don't know what is a correct/best programmer connector to use. There are 6 pins in Discove...
Posted on September 23, 2016 at 20:00I am losing my mind, I start cubemx, installed stm32L4 library, configure the clock HSI , as this board has no HSE, GPIO and SPI, choosed MDK 5, I generate the code, and try to test GPIO using Hal api, nothing h...
Posted on September 23, 2016 at 18:33Hi everyone! I'm having some difficulty getting variables to be declared in external SRAM. I'm using a STM32L4. If I do address casting like the FMC example project for the eval board in the library code I can...
