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...
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...
can anyone help me to know the reason for this unusual behavior or what am I missing here.
