#stm32f4-discovery

[myzharbot]

Finally the sonar module PCB is ready to be sent to service to be CREATED. Me and Mauro Soligo have chosen a name for it: RoboDiscovery-F4. We also decided to dedicate a website also to this project: www.robodiscovery.com is coming.

Features:

2 strips to fit STm32F4-Discovery board

Zigbee ready

16x muxed connectors for HC-SR04 sonar sensors

16x RGB leds to monitor the status of each sonar

I2C barometer

1x RS232 Serial Port

1x RS485 Serial Port

1x BMP085 Barometric Pressure Sensor with icnluded Temperature Sensor

USB or external power

Motor Control interface: 2 Encoder connectors + 2 PWM outputs

The full project with Schematics, Firmware (not yet complete) and Gerber files, is available on Github inside “LLU” folder:

With Mauro Soligo from katodo.com we are creating a support card for STM32F4-Discovery to handle up to 16 modules sonar (HC-SR04) for robotics applications. MyzharBot will use only 4 sonar sensors, but larger robots will be able to leverage the power of the new board.

As usual the board is openhardware and the schematics are now available on github.com under LLU module with the full firmware that is still in beta testing. The firmware will be based on the new STm32CubeMX tool that make the development for STm32 MCUs very very fast!

The board will not only be able to drive 16 sonar sensors, but will have 16 RGB leds to monitor sonars functionality, it will use the accelerometer present on the STM32F4-Discovery and will have plenty of other functions… stay tuned.

Why hello there, ADF7021.

What's awesome and sitting on my desk?

Lua (more properly eLua) running on an STM32F4 Discovery board. Flash image clocks in at ~584k.

It's 1987. You're in Sears. You know a few words of BASIC, and there's an Apple 2 demo unit.

I have matured somewhat, and now meter them out in controlled bursts as needed; this one has a nice staircase effect.
