STMPE610 Library

[karl567]

Please, where can I find the STMPE610 Library for my mikroPascal PRO Compiler (v6.2.0)?

Hi,

Currently, porting of this library for dsPIC compiler is in our plans.

Filip.

Hi,

thank you for your answer. Could you please specify how long the porting will take? Or could you provide a preliminary version of the library? Currently I am working on a project with STMPE810 and it would be very helpful to for me to go on.

Regards,
Karl

Can you share the stemp810 registers initialization values? I own the mx7mmb and can not get a steady touch reading.

Hi,

Are you interested in some specific registers ?
Many of them are used by the library, it will be difficult to list them here.

I am interested in the driving strength and timing registers. The touched point jumps quite a lot.

The other board I own, the green mx7mmb (with ADC touch) is very steady.

This is the actual code:

Code: Select all

    if (STMPE610_get_version() == 0x811) { // chip ID
        write(STMPE_SYS_CTRL2, 0x00); // turn on clocks!
        write(STMPE_ADC_CTRL1, STMPE_ADC_CTRL1_12BIT | (0b110 << 5)); // 124 clocks per conversion
        write(STMPE_ADC_CTRL2, STMPE_ADC_CTRL2_3_25MHZ);
        write(STMPE_TSC_CFG, STMPE_TSC_CFG_4SAMPLE | STMPE_TSC_CFG_DELAY_500US | STMPE_TSC_CFG_SETTLE_500US);
        write(STMPE_FIFO_TH, 1);
        write(STMPE_FIFO_STA, STMPE_FIFO_STA_RESET);
        write(STMPE_FIFO_STA, 0);
        write(STMPE_TSC_I_DRIVE, STMPE_TSC_I_DRIVE_50MA);
        write(STMPE_INT_CTRL, STMPE_INT_CTRL_POL_HIGH | STMPE_INT_CTRL_ENABLE);
        write(STMPE_INT_EN, STMPE_INT_EN_TOUCHDET | STMPE_INT_EN_FIFOTH | STMPE_INT_EN_FIFOFULL);
        write(STMPE_TSC_CTRL, STMPE_TSC_CTRL_XYZ | (1<<4) | STMPE_TSC_CTRL_EN);
        write(STMPE_INT_STA, 0xFF); // reset all ints
        return (1);
    }

Code: Select all

TOUCH * STMPE610_read (TOUCH *touch) {
    if ((read_byte(STMPE_TSC_CTRL) & STMPE_TSC_TOUCH_DET) == 0) {
        touch->x = -1;
        touch->y = -1;
    }
    else {
        if (read_byte(STMPE_FIFO_SIZE) > 0) {
            touch->x = ((COORD)read_word(STMPE_TSC_DATA_X) - 172) / 8;
            touch->y = ((COORD)read_word(STMPE_TSC_DATA_Y) - 280) / 13;
        } else {
            return (0);
        }
    }
    write(STMPE_FIFO_STA, STMPE_FIFO_STA_RESET);
    write(STMPE_FIFO_STA, 0);
//    printf("%d ; %d\n\r", touch->x, touch->y);
    return (touch);
}
