2、CPLD-------QUARTUS7.0
3、运行CDM_Setup.exe安装FT245的驱动程序
4、插上USB线，电路上电后，会提示自动安装驱动程序，如果安装成功，可以在设备管理器中看到Altera USB-Blaster
4、运行MProg3.0_Setup.exe，将altera.ept文件烧入FT245RL的内部EEPROM（FT245BM是在外部94LC46中）
5、打开QUARTUS，就可以在下载器中发现USB-0（USB-BLASET），正常下载了-1, schematic----- AD6 .7 2, CPLD------- QUARTUS7.0 3, run CDM_Setup.exe driver installation FT245 4, plug in USB cable, power circuit, it will automatically prompt install the driver, if the installation is successful, you can see in Device Manager Altera USB-Blaster 4, run MProg3.0_Setup.exe, the file will be burned into the FT245RL altera.ept internal EEPROM (FT245BM is in the external 94LC46) 5, open the QUARTUS, you can download the device found USB-0 (USB-BLASET), the normal download Platform: |

Description:
The purpose of this project is a simple and easy to use USB <> CAN bus interface. Heart of the circuit is an Atmel AVR ATmega162 microcontroller which controls the Communication between FTDI FT245BM USB to parallel converter and Philips SJA1000 Stand-alone CAN bus controller.
The SJA1000 is memory mapped into memory space of the AVR, which reduces data and address line handling and increases data transfer speed.
An FT245BM handles all USB communication and provides data transfer from and to PC application. An extra EEPROM can store the multi device template for the FT245BM.
A Philips PCA82C250/251 works as CAN controller interface.
Firmware is written in C, compatible to latest compiler version WinAVR. Platform: |
