error compiling for pico

[tonluc123]

Hello, I tried to run example as is with no change at all with arduino ide and got:

C:\Users\PC\Documents\Arduino\libraries\CST816S\CST816S.cpp:27:10: fatal error: FunctionalInterrupt.h: No such file or directory 27 | #include | ^~~~~~~ compilation terminated. exit status 1 Error compiling for board Raspberry Pi Pico W.

Arduino: 1.8.19 (Windows 10), TD: 1.56, Board: "Raspberry Pi Pico W, 2MB (no FS), 133 MHz, Small (-Os) (standard), Disabled, Disabled, Disabled, Disabled, None, Pico SDK, Worldwide, IPv4 Only, Default (UF2)"

Any ideas of what is happening with the cpp file ? Thanks Lucas

OK. in CST816S.cpp you'll see:

attachInterrupt(digitalPinToInterrupt(irq), tp_isr, FALLING);

with tp_isr being:

static void tp_isr() { tp_event = true; }

This means: when the pin labeled "irq" does from high to low, call the interrupt routine tp_isr(). tp_isr() sets the variable tp_event.

This attachInterrupt probably needs to be modified for a pico.

I have seen a similar report for this issue with your answer that this lib only supports esp's and I was wondering if there was any progress from you or anyone else concerning this issue. Sorry for this, I understand that you guys do all the job and we use your lib's without any struggle. My struggle is with a gc9a01 from waveshare that happens to use this chip. Lucas

I'm using this library on stm32 and Chinese stm32-lookalikes.

You could try going from interrupt to polling. in cst816t.cpp: in void cst816t::begin: comment out the line with: attachInterrupt(digitalPinToInterrupt(irq), tp_isr, FALLING);

in bool cst816t::available()

• add: tp_event = !digitalRead(irq); between "uint8_t dta[6];" and "if (tp_event && !i2c_read..."

The main thing is: when the pin "irq" goes down, read the registers of the chip.

Hi Koen, No luck with those changes but I managed to make it work with this: (bottom of the page) https://forum.pjrc.com/index.php?threads/issues-with-cst816s-controller-libraries.73180/ Lucas

OK.

IIRC, the "NONE" is if you poll the controller but the screen hasn't been touched since the last poll.
