Max7219.. Simple question

[sodeaf]

I am using a 20x2 with max7219.. I have the CLK, DATA, and LOAD connected directly from chip to chip.. No resistors in the line, or resistors from the lines to ground or 5 vdc.. Is this correct? Should I tie any of these lines high or Low with a resistor? Or install any in the lines it self?

It is working fine, but for future stability I was wondering if I should add resistors..

Thanks
Steve

They are all inputs on the MAX7219, so direct connection is fine. However, you may want to tie LOAD (/CS) high (10K to +5v) to avoid false signals finding their ways onto the displays under obscure circumstances that may or may not apply in your software/circuit design (the PICAXE output pins being made inputs for a period of time, startup immediately after power on etc)
