Hi Vlad and people, Now I have connected 2 max 7219 CNG chip, with 2 5 digit common cathode display, and following the connection as simvim page, and only works the display number 1, Im triying to see com1 act and standby frecuencies in 2 5 digits displays, but I dont know what happend now, please if you can help me.
I dont know if have any problem with max7219cng chip and unsable digits, or ISET resistor (try with some types of values).
to answer this question.
How do you connect the second display? They both should be configured to different outputs.
I use 2 diferent pins for differents outputs, for example pin 30 and 31 to CLK pin in 7219, DIN and LOAD its the same for both...
PLease Vlad, if you can post a schematic for 7219CNG chips, the config parameters I'll be very greatful Thanks!! check your mail, I sent to you a G1000 pcb board :)
