Adding a new write characteristic and notification characteristic
Hello! I created a new project in CubeMX and activated the BLE so as to work with P2P Server profile. I want to add new characteristics besides the standards ones: write and notification. I saw videos of ST Workshop (how to modify profile and add fun...
DMA misunderstanding (burst, data alignment, FIFO)
While I was reading a book about DMA I came up with some questions. I tried reading AN4031, RM0090 with no better luck in understanding.The problem has to do about bursts in DMA. The questions are theoretical and there is no source code to follow the...

Hi folks,i recently tried to migrate my SSD1306-I2C-display driver using DMA from "STM32Cube FW_F1 V1.6.1" to the latest "STM32Cube FW_F1 V1.8.0".The driver uses HAL_I2C_Mem_Write_DMA(..) routines and worked just fine on the old Cube firmware. Now wi...
3x CAN with STM32F7
I plan to use an STM32F7 to adress three different CAN-Buses. As the spec sheet says there are 3 available I don't see a problem. However the reference manual talks about a dual and single CAN Bus architecture with CAN2 being the slave of CAN1. Is it...
