Posted on May 30, 2018 at 07:19Hello everyone, i am using stm32F429ZI nucleo board and i want to implement mqtt over LWIP,i am able to send connect request and publish dummy data on mqtt server but after the keep alive time socket error occurs, i ha...
Posted on July 04, 2018 at 00:30With STM32F40x-ZG, I want to run OTG_FS and UART1. But I found that the OTG_FS_VBUS line is shared with USART1_TX line for the device. Does it mean that only one of them can run while the other is disabled ?Or can th...
Posted on June 26, 2018 at 10:03Hi everyone,I'm working on an STM32F1 platform. I have a problem with the LSE crystal. I'm using this one ABS07-120-32.768kHz-T by Abracon. The problem is with temperatures below 5�C. I made some calculations accordin...
Posted on July 02, 2018 at 22:12Hi,I am working on Nucleo-144 ADC, trying connect ADC pin to read. From RM0351 Reference manual, there are 3 ADC while the Nucleo-144 user manual has pin like ADC12_IN8, ADC123_IN1.What's those means - ADC12, ADC123? ...
Posted on July 04, 2018 at 02:05Hi,I uses ST-LINK CLI command '-P <file> 0x20000000' to load data file to sram. When the load isfinished, the MCU is alsorested.It is possible to use st-link CLI to download the data to the on chip sram without reset ...
Posted on June 19, 2018 at 18:29 I am trying to configure the TIM2 to act as an up/down counter as describe in Encoder mode 1 or 2. I have the circuit set up to connect PB8 to a count signal and PB9 as a direction signal. I have am having an iss...
Posted on July 03, 2018 at 17:03I cannot communicate my mpu6050 with nucleo-F103RB board via I2C interface. Here is my code, maybe someone could explain me what is wrong.&sharpinclude 'stm32f1xx.h'I2C_HandleTypeDef hi2c;UART_HandleTypeDef uart;void ...
Posted on June 05, 2018 at 13:25I believe I do not violate any forum policy here. I do not want anyone to break any secrets here.I am a hobbyist & STM32 enthusiast but I have never seen any real products where the STM32 was embedded (besides Sony Sm...
Posted on May 09, 2016 at 22:33I want to use CH1 and CH2 in encoder mode and also CH3 in input capture mode, all this using one timer (TIM3). Is it possible? I didn't found any warnings in datasheet. I looked at the block diagrams but I'm not sure a...
Posted on June 30, 2018 at 03:32Used latest STM32 Cube MX to generate an empty project where MCO2 suppose to output to pin PC9 using PLL2 as a clock source. However, no output happens on PC9. If I manually change MCO2 clock source in RCC_CFGR regist...
