STC15F204EA 白光T12控制器
作者： goodcode
0-500℃ 0.000-16.748mv
单片机ADC参考电压等于VCC约5v
代码中按照放大器269倍增益计算既在500度时4505.212mv
只要放大器满足此条件可以用别的也可以改变电路
关于布线
建议预留P30,P31用来升级调试
*ADC只能在P1.0-P1.7之间
T12_CTRL不能变更连接
DPY_A-DP尽量安排在一个完整的端口
DPY_DIG最好安排在相连的端口
编码器本来是想用中断做驱动 但是204EA版有bug 外部中断不可用 所以可以修改到其它端口
当然能动最好了:) 有需要变动的我重新编译固件
正常版本最近一两天放出
电路可能存在bug 希望高手指正
已知D4虚焊可能烧掉单片机IO或单片机, 这部分可以改3r33输出8v 然后7805或者串二极管到mcu
8v给lm358供电
设计可控温度在150-450℃
有自动冷端补偿
