1. Assemble the whole flash and eemprom files make uno.hex
2. Backup the current flash & eeprom values make uno.bak
3. Erase the whole MCU Flash make uno.era
4. Upload the new firmware using the hex file generated make uno
5. Set the appropiate MCU fuses make uno.fuse
6. Clear files (except backup) make uno.clr

好像还要一个叫 value 的 word

可能的文件 amforth-5.9/lib/forth2012/core/values.frt

amforth-5.9/avr8/lib/forth2012/core/avr-values.frt 定义了 Evalue i2c 需要它

cvalue 定义一个 byte 的变量，在 RAM 中。

eeprom-buffer.frt 包含 words of Ebuffer:

步骤：

1. u0 marker.frt
2. u0 builds.frt
3. u0 bitnames.frt
4. u0 synonym.frt
5. u0 ms.frt
6. u0 motor_shield.frt

对于 ada-shield v2

• 先安装 forth 环境 /home/atommann/forth/amforth-5.9/appl/arduino
• u0 builds.frt u0 avr-values.frt # for Evalue u0 i2c-twi.frt # for i2c u0 i2c.frt u0 eeprom-buffer.frt u0 ada-shield.frt
• 今天在 往 funduion 上传数据时 居然区分大小写？

  ==================================== pwm_a digital.3 \ PWM pin for motor_a OC2B PD3 pwm_b digital.11 \ PWM pin for motor_b OC2A PB3

  pin_dir_a digital.12 \ forward == 1, reverse == 0 PB4 pin_dir_b digital.13 \ forward == 1, reverse == 0 PB5 ====================================

Evalue

• http://amforth.sourceforge.net/TG/recipes/EEPROM.html
• Note Evalue was called simply value in revisions earlier than 5.3. Eallot was Ealloc and did leave the start address of the allocated memory region.
• 注意 Evalue 在版本 5.3 以前被称为 value. Eallot 以前叫 Ealloc， 并且 Ealloc 会把分配的存储顺区域的起始地址放到堆栈上。 (怪不得 ada-motor.frt 上要用 drop 指令)
• 指令 forward 1000 0 m-run 前进 参数： 1000: 是速度, 范围 0 to 4095 (0x0 to 0xfff) 0: 0#电机, 范围 0, 1, 2, 3

  backward 1000 0 m-run 后退

  release 0 m-run release 1 m-run 释放

  At least there are four reasonable commands:

  forward 800 1 m-run (speed 800 mandatory) backward 800 1 m-run (speed 800 mandatory) hold FFF 1 m-run (the motor is blocked with a power depending on ‘speed’ (here FFF). 刹车

  release 1 m-run (the motor is powerless)

  AT+BAUD=38400,0,0 38400, 8N1 修改模块的 baudrate

  step 0: hciconfig

  step 1: [atommann@atommann ~]$ sudo hciconfig hci0 up

  step 2: sudo rfcomm bind 0 07:12:05:03:51:03 1

  可以看到 /dev/rfcomm0

  如果 /dev/rfcomm0 不工作, 可以执行 hciconfig hciconfig hci0 up
