Posted on September 18, 2017 at 18:20I have noticed that STM32F7 microcontroller generates a digital noise (see the figures. It is not from transmission lines and bursts are repeating every 16ms) on the 5.0V supply voltage. I have observed this usin...
Posted on November 29, 2017 at 00:00NUCLEO-L432KC I2C3 issueI am using two STM32 L432KC board to test I2C functions. It works fine with both master and slave using I2C1 with pin PB6 (SCL) and PB7 (SDA). But I can't make it work on one side use I2C3 ...
Posted on November 23, 2017 at 01:16I just started with the X-NUCLEO-IDB05A1 board which has the SPBTLE-RF BlueNRG-MS RF module.I would like to focus on the 'Client mode' for this project. Have downloaded the 'STM32CubeExpansion_BLE1_V3.2.0\Project...
Posted on June 30, 2017 at 04:39Hi，I use CubeMX 4.21.0 to generate FreeRTOS+LWIP code on STM32F746GZ Nucleo board. The problem is when I ping the board, It will reply after pinging 2 times. See below capture:Did anybody ever meet this problem?
Posted on November 28, 2017 at 13:07 MCU: STM32F777II I am facing a very strange problem with receiving data from a UART where the data reception stops after few minutes like after >10 minutes, where initially it works pretty fine.The RX channel ...
Posted on November 28, 2017 at 06:16Hi.I have a question. I am using STM32L051 and I am wondering about the state of BOOT0 pin. When power is first applied, the boot mode can be proceed from the status of BOOT0 pin and nBooT1 After that, I wonder wh...
Posted on November 27, 2017 at 23:10Can someone please direct me to a comprehensive explanation of Multiprocessor communication using a USART. I have reviewed paragraph 31.5.7 of RM0385 and still have questions.Thank You
Posted on November 28, 2017 at 16:53Dear all,I have configured ADC - 1 channel with DMA to retrieve data. It all works fine. Now, I am trying to use the same ADC (ADC1, DMA2_Stream0) to use 2 channels (channel 12 and 13). uint16_t ADC_Value[2] = {0,...

Posted on November 27, 2017 at 09:22Dear all.I measured ACD input increasing the voltage by 10mVdc. but, there are non-nonlinear points.As the datasheet, ED and EL are +-1.5LSB and +_2LSB. It seems that my measurement result is bigger than them.Coul...
