  • Publication number: 20240048405
    Abstract: In an embodiment a method for operating a processing system includes programming, by a microprocessor during a CAN FD Light data transmission phase, a control register of a Serial Peripheral Interface (SPI) communication interface of the processing system in order to activate a master mode; generating, by the microprocessor during the CAN FD Light data transmission phase, a transmission CAN FD Light frame; storing, by the microprocessor during the CAN FD Light data transmission phase, the transmission CAN FD Light frame to a memory; and activating, by the microprocessor during the CAN FD Light data transmission phase a first DMA channel so that the first DMA channel sequentially transfers the transmission CAN FD Light frame from the memory to a transmission shift register in the SPI communication interface.

  • Patent number: 11853252
    Abstract: A processing system includes a transmission terminal configured to provide a transmission signal, a reception terminal configured to receive a reception signal, a microprocessor programmable via software instructions, a memory controller configured to be connected to a memory, a serial communication interface, and a communication system. Specifically, the serial communication interface supports a CAN FD Light mode of operation and a UART mode of operation. For this purpose, the serial communication interface comprises a control register, a clock management circuit, a transmission shift register, a transmission control circuit, a reception shift register and a reception control circuit. Accordingly, the microprocessor can transmit and/or receive CAN FD Light or UART frames via the same serial communication interface.

  • Publication number: 20230300001
    Abstract: In an embodiment a processing system includes a sub-circuit including a three-state driver circuit, wherein the three-state driver circuit has a combinational logic circuit configured to monitor logic levels of a first signal and a second signal, and selectively activate one of the following switching states as a function of the logic levels of the first signal and the second signal: in a first switching state, connect the transmission terminal to the positive supply terminal by closing the first electronic switch, in a second switching state, connect the transmission terminal to the negative supply terminal by closing the second electronic switch, and in a third switching state, put the transmission terminal in a high-impedance state by opening the first electronic switch and the second electronic switch.

  • Publication number: 20220286319
    Abstract: A circuit includes a first and a second memory, a processor and a timer. The processor generates a sequence of bits encoding a CAN frame and processes the sequence of bits to detect a sequence of PWM periods. The processor stores values of a first parameter of the PWM periods into the first memory, and values of a second parameter of the PWM periods into the second memory. The timer comprises a first register which reads from the first memory a value of the first parameter of a current PWM period. The timer comprises a counter which increases a count number and resets the count number as a function of the value of the first register.

  • Publication number: 20170370609
    Abstract: The invention relates to a counter flow enthalpy exchanger (1) having a parallelogram-shaped central part (11), whose ends in the flow direction through the exchanger it is joined by end parts (12, 13), which become narrower in the direction from the central part (11), whereby in order to separate the flow of the heat-transfer medium in the direction from the inner space to the outer space are arranged contour identical and with respect to the flowing medium sealed vapour-permeable lamellae (10) with shaping means for generating turbulent flow, whereby every two adjacent lamellae (10) form one interplate flow channel in the central part (11) one interplate flow channel. The lamella (10) is made as a one-piece self-supporting moulding common to the central part (11) and the end parts (12, 13), whereby it does not have a reinforcing support grid.
