sir, im new to quectell …im doing project on m66 and pic microcontroller…i want to communicate with microcontroller pic16f877a via uart ports …i installed eclipse, qcom, qflash, M66_OpenCPU_GS3_SDK_V2.0_Eclipse…next what should do next ?( where do i program, program references , free codes etc,)…
Hi Mohan ,
you don’t need the eclipse SDK to communicate to module , you can use UART interface of module to communicate with your MCU and then using AT command you can communicate to module .
Please note GPIO level of Module is 2.8V level so you need to have resistor divider circuit while communicating to MCU working on 3.3V . Please refer HD document .
hello ratan ,thx for ur reply…
tell me …am i need to do this ? write the c program using command sentences, directives given in open_cpu document …with the help of examples given in open_cpu and compile using gcc_compiler and need to upload program in q_flash
Hi Mohan ,
you need not to do this all .
you need to write c code in your MCU , there your MCU will send AT commands to module and get response from module over UART .
you will write UART peripheral handling for MCU to control module .
OpenCPU code is not applicable at all .
Thank you
Ratan
