Hello,
in your code you have point = point + 3/4
point is a byte and 3/4 in integer maths will be 0.
I've changed your example so that it uses a counter and simply doesn't output every fourth pulse.

The HC-12 look interesting, I might get myself a few to have a play with.

Re: Who uses cheap 433Mhz modules?
I had great success using these and they have built in detection to ensure that the data is valid before presenting it on the receiver. https://www.rfsolutions.co.uk/radio-modules-c10/alpha-c80 Unfortunatley the smaller modules at least seem to be end of life, I think in part because things like thi...

Re: FAT SD Card Data Logger
Hello, I've found what might be causing the problem. The RMC message that contains the data validity flag is usually $GPRMC but in this case it is $G N RMC. I've updated the component to allow for this and hopefully that should solve the problem for you. The other messages all seem to be ok so finge...

Re: FAT SD Card Data Logger
Hello, What are you using as your power source for the GPS? Could it be that the current is too low and this is causing your first module to give unreliable data and your second module not to boot up at all? With projects like this I have used Li-ion and Lipo cells with a lot of success. I've also u...

Re: Error message with I2C slave and 32MX220
Hello,
I'm afraid we do not currently support the I2C Slave on the PIC32 range of devices. It's something I can look into for you if you need this functionality.

Re: FAT SD Card Data Logger
Hi George,
What speed is you crystal on your board? If this doesn't match the setting in the Flowcode project options then this could be the cause of the problem.
Does it ever start logging with the L76X, i.e. tell you the data is accurate?

Re: ESP32 OLED display via SPI
Hello,
Pins GPIO34 to 39 are input only and so are not capable of digital output. Can you reconnect the display to other Pins, e.g. on PORTA or PORTB 0 to 1.

Re: IR sensors with flowcode 9
Hello,
Many thanks for letting us know on this one, sorry it took a while for us to replicate and then find the cause but this has now been resolved in the latest v9 and v8 updates.

Re: IR sensors with flowcode 9
Hello Andrew,
Many thanks for letting us know I am now in the process of investigating this one for you. There seems to be some kind of problem relating to the choice of MCU target which may or may not be causing the problem.

Please can you post your flowcode project file and I'll have a look at this for you. The gps output should be fairly standard but i will check the file you sent to make sure.

Re: Improvements for RS232 serial component
Hello Fernando, Thanks for the suggestions. The use of a FIFO buffer would rely on the interrupt being switched on behind the scenes. I beleive this is how Arduino do it, it's certainly something we can consider adding as it would simplify things for a user not used to adding their own interrupt. If...

Hello Fernando, No sorry at the moment v8 cannot simulate the RXInt, a workaround is to call the macro as part of your main program loop. You can use the IsSim component to decide if you are in simulation mode or not. In v9 we have more capability to allow us to do this via new simulation API comman...

Aha well done glad you got it working. In our bootloader firmware we check to see if a voltage on an input pin used as a USB detect pin is present when starting.
