lp tool多功能工具 3 | * lptool使用stm32f401cc做主控。利用其所有io，还有复用了几个io！以实现daplink,cdc串口，mscU盘，电流和电压检测，预留spi和iic的下载和调试功能，还有2个io。 4 | * 开源电路图(禁止用于商业)，提供boot loader(bin文件)，app地址偏移0xc000.进入bootloader模式按着key1键开机，电脑出现U盘符号，把app文件复制到U盘内即可，app文件需经过lptool.exe软件处理后。 5 | 6 | ### 使用说明 7 | * 注：按键1是模式切换按键 8 | * lpttol存在多种模式 9 | 1. 不使用usb连接到电脑。（lptool自带电池） 10 | * 按key1开机后是电流检测模式 11 | 2. 使用usb链接到电脑。 12 | * 1.daplink模式，可使用cdc串口，屏幕不刷新，保证mcu给dap独占 13 | * 2.daplink与电流监控共存。 14 | * 3.pc端监控电流模式。 15 | 16 | * 电流监控使用说明 17 | 18 | 0. 引脚图请看文章下面的[对外输入输出io]图片 19 | 1. 如需从工具中获取电源，那么请用短接帽把T1与_3.3V,或T1与_BAT短接。 20 | 2. 外界电源(不要超过18V)，T1电源正，GND电源负 21 | 3. 把T1接待测目标电源正，T2接待测目标电源负即可 22 | 23 | 24 | ### 参数说明 25 | * stm32f401cc:frequency 84M,flash 256KB,RAM 64KB,ADC 2.4MSPS,USB 26 | * 电流监控范围：1ua~3A 27 | * 1ua~3ma 范围内精度1ua 28 | * 3ma~3A 范围内进度1ma 29 | * 采集速度1K 30 | * 外挂128Mbit flash 31 | * 0.96寸 80*160 tft。(pcb兼容1.14寸tft) 32 | * 对外供电：电池电压和3.3V（与mcu独立供电），5V(连接usb) 33 | 34 | ### 对外输入输出io 35 | ![](https://github.com/lgtbp/lp_tool/blob/master/image/io.png) 36 | * 正面照片 37 | ![](https://github.com/lgtbp/lp_tool/blob/master/image/tool.png) 38 | 39 | ### [淘宝连接](https://item.taobao.com/item.htm?spm=a2oq0.12575281.0.0.22e91debeNCAao&ft=t&id=610408572525) 40 | ![](https://github.com/lgtbp/lp_tool/blob/master/image/tb.png) --------------------------------------------------------------------------------
