Hi team,
customer use TCAN4550, can read/write register via SPI and read the ID1 confirm that the communication is ok, also can configure device work in normal mode or sleep mode.
While, they use the reference code of sllc469b.zip ,sent the data to TCAN4550, find can't receive the data.
could you give some comments here? thanks.
Hi,
TCAN4550-Q1 is configured By using Init_CAN() function from main.c of sllc469b.zip,
so data rate is 500K.
Communication process as follows：
MCU send 8 byte data, the device(USBCAN-II) can't receive 8 byte data.
send code as follows:
void TestCanSend(void)
{
TCAN4x5x_MCAN_TX_Header header = {0};
uint8_t data[8] = {0x12, 0x13, 0x14, 0x15,0x55, 0x66, 0x77, 0x88};
header.DLC = MCAN_DLC_8B;
header.ID = 0x18EA0091;
header.FDF = 1;
header.EFC = 0;
header.MM = 0;
header.RTR = 0;
header.XTD = 0;
header.ESI = 0;
TCAN4x5x_MCAN_WriteTXBuffer(0, &header, data);
TCAN4x5x_MCAN_TransmitBufferContents(1);
}
The above code runs once per second
Modes of Operation and Pin Configuration Registers (address = h0800) is 0xC80004A0
