Re: Video Tutorial on Roboplus Mobile & BT-110A Module
Cannot yet comment on the BT-110A's as we haven't gotten any in the lab yet, but the CM-530 is quite nice with an STM32 (ARM Cortex-M3) and an onboard FT232 for USB to UART communication (no more USB2Dynamixel needed). Any problems with the CM-530's FT232 being powered off the battery/adapter, or is yours newer than ours?
The beta version they shipped us requires a bit of modding to which I still have not gotten around. It still works well enough without 'fixing' and I get the feeling I will end up 'breaking' it when I try to move (not just remove completely) an SMD inductor so the FT232 will be powered from USB instead of the battery. As is, anytime you flip the power switch it disconnects the USB UART connection and you must wait for it to reconnect after re-powering the CM-530 (very annoying when debugging). On the bright side, that constant disconnecting/reconnecting when working with embedded-C provided the incentive to build a very basic hardware checker/firmware pre-loader (prints out debug info similar to the robotis firmware and waits for you to press the START button before moving on to run the user program). Also has basic functions for easily using the HaViMo2; controlling all LED's, external port pins, and the buzzer; and reading all of the external port ADC pins, buttons, and the microphone. If anyone is interested, all the source code is on the Robotis Gallery site as an attachment to a HaViMo2 article.
