Posted on August 26, 2016 at 23:46 In a CubeMX (lastest version now) generated project CDC_Transmit_FS resp. USBD_CDC_TransmitPacket do not work reliable. On every few request there are no data readable on host from the device (/dev/ttyA...
Posted on December 29, 2017 at 22:50Hello,i am working on a design which uses a stm32f427 device, and 3 external adc chips.The ADC chips have 3 pins, SDO, SCK and CS.The SDO,SCK wil be shared from the STM32F4 with all 3 chips, the 3 chip select sig...
Posted on December 29, 2017 at 20:43Dear community,I just started to learn stm32 trying to forgive about AVR.The problem I faced with is I can not force my STM32F103C8T6 to read pin PB0. I`ve read both Datasheet and RM0008, I saw the examples of ano...
Posted on November 14, 2015 at 11:22 Hello, I'm trying to communicate with a STM32f4x9 EVAL board and a STM32F429-Discovery board via CAN Bus, I am using MCP2551 transceiver IC for Discovery board, I know that CAN1 is being used by LCD an...
Posted on September 02, 2014 at 23:13Hi:I am using STM3221G-EVAL board. The board has a couple of switches to select the Boot source.Boot related jumpersBOOT 0 BOOT 1 Boot source 0 1 or 0 ...
Posted on December 29, 2017 at 05:27Hi.I'm trying to use 'Boot from Embedded SRAM mode' in KEIL MDK.Where can I find reference example of 'Boot from Embedded SRAM mode' with STM32F103 ?
Posted on December 29, 2017 at 17:10Hi everyone. I have kinda dumb question...In reference manual and in libraries I am using I see that STM32F407VGT6 has ADC1, ADC2, and ADC3.But when I check the ping definition table it shows ADC12, ADC123 and ADC...
Posted on December 29, 2017 at 02:58Dear All,As I know, STM32Fxxx CPU support 3 types boot mode by selecting the Boot pins.1.Boot from main Flash memory.2.Boot from system memory3.Boot from embedded SRAM.But I want to know how to place the code to t...
Posted on December 29, 2017 at 12:16I'm trying to write a code to send data with I2C using DMA. While looking for appropriate 'Transmit complete' event I've dig into STM32Cube_FW_F1_V1.6.0 sources, to be specific into stm32f1xx_hal_i2c.c's HAL_I2C_M...
Posted on December 28, 2017 at 11:36What is the reason for ST microelectronics to have different I2C modules in STM32 mcus ?Stm32f303 and Stm32f092 has the same I2C, but stm32f446 has another I2C, and Stm32f103 has the third type of I2C. #i2c #stm32
