![]() ![]() ![]() This should be given properly by Gnd-Gnd, Vcc-Vcc, Sck-Sck, MISO-MISO, MOSI-MOSI, RST-RST.Ģ) Check whether the power to the ISP Programmer and micro-controller are correctly supplied. Many times Gnd,Vcc,Sck,MISO,MOSI,RST connection does not match with each other. This can be solved by checking the connection between Serial ISP Programmer and Micro-controller. 7 segment LED display is very popular and it can display digits from 0 to 9 and quite a few characters like A, b, C., H, E, e, F, n, o,t,u,y, etc. This article is about how to interface a seven segment LED display to an 8051 microcontroller. from port 1 to port 0).Ĭompiler, and load flash of hex file againġ) Main reason for this error could be wrong connections.
