求助arduino pro mini
本帖最后由 Kevin.L 于 2017-7-3 17:44 编辑
各位大神帮帮忙!我是新手。前面入手了两块mini Pro 板子, 使用ftdi 的 ft232rl 下载器,有六路接口,都是匹配的。连线正确,程序上传时显示
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x70
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x70

插电时led闪烁,证明BootLoader 也没问题, 接口只显示com4,板子选对了的,线连对了编程器选的是默认的 avrisp mkii, 网上说要下载时reset一下,我连了dtr,下载时板载led闪烁,说明被reset了,不知道哪错了,各位大神救救我!!
连线图发出来再看一下,另外Pro mini 有5V和3.3V两个版本,你选的是哪个?
PS:尝试一下Arduino UNO 这个版型,看看行不行 我的是5v,用mega2560试了,没问题,但mini就是不行,用的是ipad,不太方便回图 手动复位一下吧,dtr复位不太稳定 试很多方法发现还是手动复位成功率高,当出现“上传”字样时,马上按下复位,成功率在80%以上 编程器是选arduino as ISP,RST那个线换一个脚位连,板子上好几个RST pin.
