Re: VL53L0X1 Showing only High Repeated Number

Thank you for your reply. Yes you are right, I reconfigured my program for the UNO and it worked but only on short range. I also boot loaded an Attiny85 at 16MHZ and it worked on short range not long, I do not know why.

VL53L0X1 Showing only High Repeated Number

Hi everyone, I am working with the VL53L0X1 component. As per the attached program I am only getting the value 7903mm from the module. The component is set to long range. I tested other modules and I got the same result. I looked at the forum and no solution for my problem. I am using an Attiny84 ch...

Re: AJ-SR04M Returning 9999 while using the AJ-SR04M Component

Martin, the program works very well. This will further my understanding of Data Arrays. I will now be able to use the conversion block in my programs.

You are always such a great support for us.

Thank you very much and everyone for your great help.

Regards,

Re: AJ-SR04M Returning 9999 while using the AJ-SR04M Component

Hi Martin, you are amazing, I have done a lot of flowcode over the years but this is the first time I have to read and convert data of this kind from a UART. Great work. I will test it tonight and let you know. This helps me to understand the String manipulation at greater level.

Regards,

Re: AJ-SR04M Returning 9999 while using the AJ-SR04M Component

Hi Martin and everyone, I was able to use Martin's idea and wrote a program that worked just fine for my application of water level reading. Martin, I have worked with the AJ-SR04M on the #2 mode. That is the one that sends Hex data through the UART at 9600 baud. The data is 4 bytes. Start byte, MSB...

Re: HexToDecimal

Thank you everyone for your replies. Sorry, I could have written more details. I started this thread in the embedded projects and I should return there as it is regarding the AJ-SR04M ultrasonic module. I will ask the question there and make myself clearer.

HexToDecimal

Hi everyone, I search the forum and could not find a way to convert HexToDecimal, function or otherwise that I could use while reading UART data. IE: receiving bytes and convert so I can read Hex data and convert it to a usable form. Does someone have a solution? Thank you for your help. Regards, Pi...

Re: AJ-SR04M Returning 9999 while using the AJ-SR04M Component

As usual a great thanks to your Martin and the others for your replies and work. I knew this was the problem but I was not going to change to component internal code. So the best is to look for another sensor or use a variation with a resistor on R19. I was aware of the R19 function but hopping I co...
