If authorities are warned in advance, they will be more cautious and inform drivers in advance. This is to prevent accidents because the snow may reduce visibility for drivers and pedestrians. There should also be proper signs to indicate to drivers that they are approaching a road plate like “road plate ahead,” “bump,” or “caution: road plate ahead.” If road plates are used during the winter, it is important to notify local authorities of where they are. The edges must be marked so that the plate is visible for drivers and cyclists. make sure to shift the address of nucleo if the i2c master using 7-bit i2c address format (i.e. If needed to counteract the uneven roadways, the plates must be countersunk. NUCLEO-F042K6 NUCLEO-L432KC NUCLEO-F446RE. Usually, this means that the plate extends beyond a foot in order to meet that requirement. Captive Panel Hardware- Screws, Retainers, Decorative Panel.
In this way, if you have two sensors on your application board, you can connect them to the same I2C (SDA and SCL) lines, since they will have different I2C addresses. It is necessary that the road plate extend beyond the gravel of the construction site onto solid ground. Yes, you can choose the two of them indifferently, by connecting the SDO pin either to GND (resulting in the I2C address 0xD5), or to Vdd (resulting in the I2C address 0xD7). It is usually made of asphalt and other filler substances (called bitumastic material) and it is a safety measure to make sure the plate is not too abrupt in the middle of the road which could be hazardous. Until yesterday it worked normally I was trying to communicate wit a hcsr04 sensor (ultrasound proximity sensor) with i2c since it was supported and I definitely messed up the pin config (I believe so because that's the only logical explaination). When the steel plate is installed and becomes a road plate, a tapered ramp is used to connect the roadway with the edges of the steel plate. Additionally, a material that increases friction may be used as another safety measure-especially for motorcyclists and bicyclists. The amount of anti-skid coating used is usually dictated by federal, state, or local requirements. Anti-Skid coating is often applied to plates that will be used as road plates so they are less slippery. If multiple steel plates are used as road plates during construction, it is important that they are welded together at their longitudinal seams to make sure that they do not detach from one another which would be very dangerous. No success.Important safety measures are required for the safe use of road plates to ensure that they are properly installed, properly skid-resistant, and properly marked to reduce hazards for cars, trucks, motorcycles, and bicycles. I also tried the same procedure with a custom F103RC board.

BR, Jan MCUExpresso (MCU Expresso) March 4, 2022, 5:42pm 4 Dear Jan, Yes, you are right, wrong P/N. In fact, you can use the same pin names (A0, A1, etc.) when programming in Mbed. Nucleo-F446RE i2c GPIOExpander Keil Studio MbedOS 6.15.1 Check wiring and pull-up resistors. Here is the top-left side: You’ll see that the pin assignments is very much like the Arduino UNO.
With a scope, I probed every pin on the board. The ST Nucleo F103RB page on the Mbed website contains information about the Arduino header pins of the board.

Sensor is OK (with my Arduino Mega and other AVRs, the sensor works as it should).Īfter much trial and error, I took another Mac I had, fresh install of MacOS (10.13.6), fresh install of Arduino (1.8.5), used board manager to get the latest stm32unino (2018.7.2) and tried i2c_scanner. I tried both PB6/PB7 and PB8/PB9 to no avail. endTransmission always returns error 4 (other error). I am using a Nucleo F103RB and a si7006 humidity sensor with the recommended 100nF cap (VDD-GND). bin-file I could identify which core and version I used?Īnyway, I2C doesn't seem to work now.
Since I didn't constantly test I2C between every update, I don't know exactly when it broke. If you are completely new to the STM32 Nucleo64 Development Boards, do check out this Nucleo64 Review video to understand the basics of this board before you proceed further.

I got it working good in March (if I remember correctly), but not after a board and/or Arduino IDE update. Nucleo64 Development Boards are low cost and easy to use platform for professional developers as well as for hobbyist. Hello! I am trying to get I2C working with my Nucleo F103RB board.
