Code question

[stef9998]

Hey mattdibi, first of all thank you for your work.
I am planing to build a wireless numpad to use with the same receiver as the redox, which is why I am trying to understand the code.

So I was wondering, if this 10 in the Code is just MATRIX_ROWS

redox-w-firmware/redox-w-receiver-basic/main.c

Line 123 in a193645

nrf_drv_uart_tx(matrix, 10);

And should thereby be replaced with nrf_drv_uart_tx(matrix, MATRIX_ROWS);?
