Hi,   I'm working on STM32F407VG board. Try to get USB Host CDC working. I'm able to get enumeration working. The data can be sent to device. But the data is wrong. For example, "Hello"(48 65 6C 6C 6F) is send from Host. But the device received "00 00 00 00 A7".   Here is the GPIO init: GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9 | GPIO_Pin_11 |… (Show more)

There were questions on how to read UART data using DMA in efficient way when you don't know how many bytes you can expect.   U(S)ART peripheral can work very good by using RXNE (Receive Not Empty) for each byte separatelly. In this case, every received byte is manipulated by CPU by jumping to appropriate UART interrupt service routine. To allow… (Show more)

Hello, I'm evaluating the SPBT3.0DP2 as a replacement for an AMBER AMB2300 module, which is used in a RS485 to Bluetooth converter device designed around 2007. This converter is used to communicate an Android mobile phone application with an automation controller. The Android application emulates a serial terminal, behaving like an old Televideo… (Show more)

Hi, i have working HID example with me. But i was trying to integrate CDC class in the existing HID class. I am using cubemx code. After initializing and flashing i got the error as "Device Descriptor Request Failed" .   I am confused to initialize the USB driver for HID and CDC as well at the same time.   Is it fine if i initialize the code… (Show more)

I don't know if there's a non-forum place to send CubeMX bug reports, so I'm putting it here.   I found this when generating a CubeMX project for the STM32L452 with the I2C ports created using LL code..   In the I2C initialization code, at the end of the MX_I2Cx_Init() function (where "x" is the I2C port number) there is a line:… (Show more)

I found only more requests of the same in this forum and no answers. Using Hall sensors for motor control is most typical today. 6-step BLDC code example provided in X-CUBE-SPN8 is sensorless only. There are driver files in X-CUBE-SPN8 package specifically made for Hall sensored control (stm32f4xx_hal_tim_ex.c and stm32f4xx_hal_tim_ex.h) but no… (Show more)

Hi,   i have a very strange behaviour on my STM32L433CCTx.   Im am configuring the ADC with STM32Cube FW_L4 V1.10.0 to measure multiple channels. As long as i configure 5 or less conversions in the regular conversion group, everything works out fine, i start conversion with HAL_ADC_Start_DMA() and get my results after HAL_ADC_ConvCpltCallback… (Show more)

No matter the license, you ST.M. are co-owner of all the applications generated by CubeMX. I think the price of using the CubeMX generator is a little bit too high. Let the programmer generate his own license on the code, as any IDE software does. Not as an addition, but the main and only license the programmer decide.    You have the drivers… (Show more)
