Problem: i2c with DMA
To exchange data with my display I am using the i2c protocol. I decided to exchange data with the DMA but I have problems. Without DMA everything works perfectly. Communication does not go well with Dma. The configuration is the default, and the only...
Does the default location of NVM database interfere with enabling readout protection on BlueNRG-2?
Enabling readout protection on the BlueNRG-2 requires programming the last two words of flash to some value other than all 0xFF's. These two locations are 0x1007FFF8 ans 0x1007FFFC. The default standard memory map for the BlueNRG-2 places the NVM reg...
BlueNRG-2 low level radio code: how to deal with received packets with crc error
I am trying to program BlueNRG-2 device with low level radio APIs. Every time a packet received with crc error, the time schedule of the communication is disrupted, since the time is random for packets with crc error. I wonder how to disable the inte...
What is the maximum audio sample rate of the BlueNRG application?
In the BlueNRG example application the maximum sample rate is 16KHz. Is it possible to increase it without compressing the samples further (just increase the BLE bandwidth)?
Is this USB-OTG design correct? It does not work for me and I do not know why
Hello, I look for solutions for a problem that I have.I am designing a USB-OTG stage for the STM32F469ZIT6 microcontroller.What I'm looking for is that through a pendrive with standard type A connector can automatically load a .bin application.The pr...
nucleo_f401re.h of X-Cube-BLE1 software pack not found
Hi,I am exploring X-NUCLEO_IDB05A1 with STM32F401RET Nucleo, and I'm following Tutorial 7 – Using the X-Cube-BLE1 software pack (UM1718) , I'm getting build errors in console. Errors like:..\Src\app_x-cube-ble1.c:37:27: fatal error: nucleo_f401re.h: ...
How to use the Arduino Connectors with the STEVAL-STLCX01V1 with the STEVAL-STLCS01V1 MCU
Hello.I want to use the Arduino Connectors on the STEVAL-STLCX01V1 board.I know that i need to use the GPIO functions (in the "stm32l4xx_hal_gpio.c" library):void HAL_GPIO_Init(GPIO_TypeDef *GPIOx, GPIO_InitTypeDef *GPIO_Init) void HAL_GPIO_DeInit...
