Posted on March 19, 2015 at 13:09 Hello, I am using STM32F0 HAL Drivers to access external EEPROM 24C64 with STM32F The functions I am using areHAL_I2C_Mem_Write/Read but the communication is not always successful. Also it worked while using smd...
Posted on August 27, 2015 at 12:18Hello there,Trying to handle USB connection / disconnection event I realize that in stm32l1 usb api, there are no call to HAL_PCD_ConnectCallback neither HAL_PCD_DisconnectCallback as there are in STM32F4 !The sessi...
Posted on August 31, 2015 at 15:31Hello to all,I'm trying to implement a printer class for the USB. Currently I'm using the STM32F4 Discovery.I already have working the detection of the printer (EPSON CX5600) , reading the ID, etc.What I cant make w...
Posted on August 02, 2015 at 13:43Hello all! I use STM32F4Discovery (embedded code based on HAL v1.6.0) paired with libusbk. To switch on/off the isochronous IN transfer over EP2 i send commands (control transfer) to EP0. The maximum size of EP2 pac...
Posted on October 16, 2013 at 21:03Hello everybody,I am stuck during these last days with my STM32F429i-DISCO.I tried to use it as USB device, CDC class as a VCP.I have configured the as USE_USB_OTG_HS, USE_EMBEDDED_PHY.Configure the HS_ISR, Enable ...
Posted on August 28, 2015 at 17:09Hello everybody,I'm using USB CDC in my project with STM32L151CC, and I got little issue with the USB Library.I know that the MAX SIZE of EP0 buffer to transmission is 64 bytes.In my debugs, I could send 1 byte, 2 b...
Posted on August 28, 2015 at 11:06Hi. I am using STM32F070CB with libraries STM32F10x_L1xx_F3xx_USBL(v4.0.0) and STM32F0xxSPL(v1.1.0) to implement custom HID to implement simple hello world(PC sends 64 bytes and MCU sends back the same 64 bytes)The ...
