Here is the pattern I have been trying to generate for a 8×8 matrix display such that each led being lit represents a particular count:

00000001

00000010

00000100

00001000

00010000

00100000

01000000

10000000

10000001

10000010

10000100

10001000

10010000

10100000

11000000

11000001 and so on….. until all the bits become 1.

I was able to shift the the bits from right to left, such that 0x01 becomes 0x80, but how do I hold the MSB in its place and start shifting a new bit from LSB(from right side) as described above?

void MAX7219_SendData(uint8_t address, uint8_t data) {
    uint8_t txData[2] = {address, data};
    MAX7219_CS_Low();
    HAL_SPI_Transmit(&MAX7219_SPI_INSTANCE, txData, 2, HAL_MAX_DELAY);
    MAX7219_CS_High();
}

I use the above function to talk MAX7219 IC via SPI.
