As soon as I add USART initialization, SPI starts sending data using LSB and receiving with MSB(as it was intended) bit order.SPI init code:/* SPI configuration */ SPI_DeInit(); /* Initialize SPI in Slave mode */ // SPI_Init(SPI_FIRSTBIT_LSB, S...

We develop electronics for controlling multiple stepper motors and use the L6470 as drivers. Radiators with fan cooling mounted on the chip of the driver (above). The current does not exceed 2 amperes. Radiators remain cold.The problem is that driver...

Posted on June 10, 2011 at 14:50Hey! I'm trying to make sensorless BLDC control unit on STM8L15xxx MCU. High-side switches of drive circuit are opened by logical ''1'', and low-side - by logical ''0''. So I need to perform six-step trapezoidal com...
