Assistance with 2 small Microchip projects We have 2 projects written for PIC16F18346. One reads push button input from (14) 8-bit shift registers and lights 112 LEDs via Maxim LED drivers, both over SPI, and the other project implements a PID servo loop to control two small DC motors on "flying faders". Both projects send/receive control commands to a host over RS485. Both projects are working and complete. These two firmware... 6 C 编程, 工程, 电子, 微控制器, 电機工程, 嵌入式软件, 印制板布局, Arduino, 通讯工程, 电路设计 Apr 20, 2018 今天6天 22时 $424
