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...
Posted on September 23, 2016 at 11:06Hi, I am using STM32469I-Evaluation board (384KB SRAM and 2MB flash), Cube MX version 4.16, SW4STM and AC6 tool chain version 1.8v (32bit OS) and ST-Link V2.1 debugger (firmware version V2.J27.M15). I have create...
Posted on September 23, 2016 at 12:07Hi to all i have this problem, i have a STM32L152RE with a temperature Sensor, this sensor use 1-wire protocol,the data is codifing with pulse width, lather the mcu start the connection the sensor give the 40 bit...
Posted on September 23, 2016 at 12:26APB2 clock: 100Mhz ADC clock: 100/4=25Mhz Data resolution: 12bit One conversion time = 15/25 = 0.6us, 6 conversion is 3.6us But in real environment when i test on device i got the result: 6 conversations = 1.8us ...
Posted on September 22, 2016 at 09:39hi guys im currently working on the STM32407G-DISC1, the goal is RTC usage. HWlib is HAL. Below i posted the RTC related code. I did check both the CubeMX autogenerated code as well as the F4 RTC example as we...
Posted on September 22, 2016 at 19:04Hello, latest device headers for F2/4 still don't define FLASHSIZE_BASE as headers for L1/2/4 and F0/1/3/7 do. Please consider to add. Thanks
Posted on September 23, 2016 at 08:56 Hi. Mypurpose is receive data from usart and write it into file in SD card. I use SDIO 1wire and STM32cube MX. this is my code #include ''stm32f4xx_hal.h'' #include ''fatfs.h'' SD_HandleTypeDef hsd; HAL_S...
Posted on September 19, 2016 at 10:54Hello! I use a basic timer 6 to make a simple delay. Here is my code:#define DELAY_TIME 10#define PB2_ON() GPIOB->BSRRL = GPIO_Pin_2#define PB2_OFF() GPIOB->BSRRH = GPIO_Pin_2//Config PortB_P...
