I need to get the PulseIn function to work on the Photon. I started trying to fixing the errors, but I fear it might be a bigger problem than just getting it to compile due to timing differences in the Photon? It is @timb code that I am using. There have been discussions by @peekay123 around the …

would LOVE to have a working PulseIn function for the Photon. The following compiled for the Photon, but results were inconsistent at best and more likely random. I successfully use this code (less the PIN_MAP declaration in the first line of the function) for the Spark Core at present. unsigned lo…

Yeah, stuck at same error here. I am working on a Photon remote control stream parser, and I was trying to use a pulseIn function. I know the functions referenced belong to a STM library, but don’t know which is the right one for the photon and where I could find the sources (.h and .cpp).

This is the one which worked well for me on the core : Rockvole/indoor-air-quality-dashboard/blob/master/libs/ShinyeiPPD42NS/function_pulseIn.h /* Copyright (c) 2014, Timothy Brown All rights reserved. Redistribution and use in source and binary forms, with or without modification, …

Yeah, but still I am getting the same errors: ../../../build/target/user/platform-6/libuser.a(remocon.o): In function `pulseIn(unsigned short, unsigned char)': remocon.cpp:70: undefined reference to `GPIO_ReadInputDataBit' remocon.cpp:77: undefined reference to `GPIO_ReadInputDataBit' ……

What other #include statements had you put in your code for this piece to compile?

I have never got it to compile on the Photon, only the core.

K. So I did a bit of Google searching and found this: uint8_t GPIO_ReadInputDataBit(GPIO_TypeDef* GPIOx, uint16_t GPIO_Pin) { uint8_t bitstatus = 0x00; /* Check the parameters */ assert_param(IS_GPIO_ALL_PERIPH(GPIOx)); assert_param(IS_GET_GPIO_PIN(GPIO_Pin)); if ((GPIOx->I…

So, good news is this code really works. In the Photon. Yes. That’s what I’ve got. Photon. Not Core. I have rigged pin D4 of my Photon with an IR receiver . Then I’ve successfully entered some serial debug messages to know if my code was parsing serial bits into integer values. Looks like I’ve got s…

Still stuck at this, I found it is really hard to debug IR codes when the processor resets itself from time to time with no apparent reason given. Maybe I’ll open up a topic for requesting that someone writes a port of the IRremote library for the Photon.

Good news, I’ve just realized (through a compilation error in my project - “duplicate definifion of void ReadInputDataBit() function” that the particle leprechauns have implemented this STM32Fxx GPIO function for the photon, as long as STM32_Pin_Info* HAL_Pin_Map() as well. Perhaps soon we’ll have …
